No. Mimicry is when an organism pretends to look like it is harmless. For example the walking stick looks like a stick but it is not harmless.

What does the word writing process mean?
Yes, first you need to pick a topic. The next step is to research the topic. After this is you have to go through your research and begin to orginize it. You then write the rough draft, edit it, and finalize it. Sometimes you might want to do two or more rough drafts. In literal terms, it can be considered a process, much as the process of breathing keeps you alive. Writing is not quite as autonomous as breathing, but it is just as natural and necessary. Let me explain: The steps of breathing can be explained in technical terms. Something like a signal goes out from the brain indicating the need for more oxygen and the exhalation of CO2. The diaphragm expands and contracts in response, causing the lungs to expand and contract, taking in air and expelling waste gases. By the repetition of this process, we continue to live. Writing is similar to the extent that it is a natural drive or instinct. More accurately, it is an expansion of that drive or instinct. Humans must communicate. Communication is interaction with other humans or personalities. The loss of this interaction causes the loss of sanity. Humans seek to interact with and connect to those around them from the minute of their births. Emotive emissions turn to verbalized noises, becomes word sounds, becomes words, then sentences. At about the same time children begin making word sounds and words, they also begin expressing themselves visually. Doodling and drawing become part of play activity. This becomes transformed into the graphic expression of writing. We write what we speak. Writing has rules just as the spoken word does. We learn the rules of writing much as we learn the rules of speech, by mimicry, by modeling, and finally by experimentation--we strike out on our own and play with it. So, writing is a process as far as it is similar to every other biological process of our bodies. Teaching it as a process however is a mistake and does a disservice to the learner. Think about it this way, would you have the ability to walk right now if your parents had explained it to you and expected you to just perform? How can any other natural "process" be any different?

Direct-seeded (DS) culture has become increasingly important in rice cultivation. The scarcity of rural labour coupled with escalating production costs constitute the main reason for the shift in DS rice culture and its rapid and eventual adoption from transplanting. In Malaysia, wet seeding is normally preferred. The economic incentives for adoption of wet seeding were provided for by its labor saving feature as exemplified by 1-2 man day/ha vis-a-vis ca. 20 man day/ha in the transplanting rice culture. A cardinal and perennial constraint in wet-seeded rice is weed infestation, requiring good field drainage and judicious water control for satisfactory crop establishment and weed control. Farmers practising wet seeding normally use higher seeding rates, spent more on herbicide-based weed control. Some of the factors influencing weed prevalence in rice fields include the rice culture system, soil moisture regime, crop rotation, cropping pattern, land preparation and tillage regimes, light, soil temperature, fertilizer application, rice cultivar and seeding rate, as well as weed control technology. Farm surveys assessing the magnitude and extent of weed infestations in rice-growing areas are an important step in formulating an appropriate control package. Prior to 2000, the dominance of Scirpus grossus and Marsilea crenata, were registered in major rice granaries in Malaysia although Echinochloa spp. (principally represented by E. crus-galli var. crus-galli, E. crus-galli var. formosensis, E. oryzicola,and E. colonum), Leptochloa chinensis, Fimbristylis miliacea and Sphenoclea zeylanica were highly prevalent in all seasons since 1995. The rice weed flora in the new millennium were dominated by measurable and parallel increase in infestation and population density especially the four most widespread and abundant weed recalcitrant and millennial species, viz. weedy rice (WR) or Oryza sativa complex, L. chinensis, E. crus-galli complex and Ischaemum rugosum, were consistently observed. Similar trends were also observed in Vietnam, Thailand, Sri Lanka, Korea, and the Philippines. We believe that this phenomenon resulted from continuous practice of DS culture leading with continuous season-mediated accumulation of seed bank of the named weed species. It is reasonable to argue that this might be due to no selective herbicide being available to control WR, perhaps the farmer's inability and reluctance to manually control this weed at the early stage of crop growth was possibly due to crop mimicry. On the contrary, grassy weeds like E. crus-galli complex and L. chinensis can be controlled by selective herbicides such as cyhalopfop-butyl, quinlorac, molinate, propanil, fenoxaprop-ethyl and bispyribac-sodium if applied correctly. The continuous prevalence of WR calls for effective measures against the scourge aligned with other grassy weeds as the primary target of control. Crop losses due to weed competition vary with the duration of weed infestation. Integrated approach based on critical period (CP) for weed management in DS involving indirect- and direct control measures should be adopted. Sympatric weed species emerging with rice crop plants have an adverse effect on crop yields. Crop losses due to weed competition vary with the duration of weed infestation of the crops. Rice crop is likely to experience yield reduction unless it is kept weeds free during the CP of its growth duration, the phenomenon otherwise referred to as the CP of weed competition. Based on the predicted Logistic and Gompertz response curves the CP for WR control based on 5% yield loss was estimated from 16 to 53 days after sowing (DAS) in DS culture, or from 12 to 60 DAS under mixed weeds situation. To ensure weeds are suppressed during CP, pre-emergence herbicides are normally applied before or after crop sowing and these herbicides must have residual activity to control weeds at CP of weed competition. If early post-emergences are used, it should be applied at the onset of CP. If weeds still persist, late post-emergence herbicide treatments can be instituted at mid CP of weed competition. Manual weeding where necessary should be carried out during CP. Due to crop mimicry of WR, manual weeding is cumbersome in WR-infested fields. Alternatively, rouging of WR panicles must be done after CP to reduce seed banks of the ensuing crops. Choice of appropriate crop establishment technique is an important step towards good agricultural practice in rice culture. Water seeding (pre-germinated rice seeds broadcast onto standing water) appears to provide a valuable alternative to the usual wet seeding culture, and this leads to improved weed control besides providing good crop establishment. Standing water used for puddling is not drained, but conserved in the field. The presence of standing water during rice establishment significantly reduced grassy weeds particularly WR and some sedges. A major limitation of this method is seed drift, but this can be avoided with proper land preparation with the following pre-requisites, viz. the land must be flat and level; and leveling must be done with furrows during final tillage for better water distribution; minimize straw residue; use extra seed rate (30% of the normal seeding rate); use pre-germinated seeds; fields must have clear standing water maintained at 5-10 cm depth; seed treatment (with growth regulator if necessary) to ensure better establishment, and the bunds are strong and not permeable. The choice of crop establishment method should be based on WR population in the previous season. If WR infestation in the previous season is less than 5 panicles/m2 conventional wet seeding technique can be practiced. This method of rice culture can be adopted if land is thoroughly prepared to reduce WR seed bank. In situations where WR populations exceeded 6 panicles/m2, water seeding technique is highly recommended. This calls for the use of certified rice crop seeds devoid of WR. Through water seeding, water can be saved, reducing unnecessary wastage compared to normal wet seeding. In the latter practice, standing excess water need to be drained before the pre-germinated seeds can be sown. A field scale exploratory study to evaluate the impact of continuous water seeding technique in an area heavily infested by WR (at 117 panicles/m2 with usual wet seeding), registered 90% reductions in WR populations (35 panicles/m2 in the first season of water seeding and 8 panicles/m2 in the ensuing season) resulting in nearly 100% increment in rice yields.
What is it called when an organism looks like another organism that is poisonous?
mimicry
Out of which part of life does the mimicry come from?
Mimicry is when an organism copies another organism, for its benefit. It is a part of evolution. An example is how certain moths mimic the appearance of owls, to deter predators.
What is mimicry in animals?
Mimicry in animals, is when an insect will act as another insect, in appearance and/or behavior, to avoid detection from predators. Batesian Mimicry is when a harmless organism mimics a harmful organism in order to trick predators. Examples of this would be the Scarlet King Snake, and The Eastern Coral Snake.
What is the difference between Batesian mimicry and Mullerian mimicry?
Batesian mimicry is when a harmless species or a species that is prey to predators (some textbooks might use the word 'palatable', which means savoury or tasty) copies a harmful species or a species that is not prey to other predators (unpalatable, which means unsavoury, not tasty). On the other hand, a Mullerian mimicry is when TWO (or more) harmful or unpalatable species mimic each other. These animals usually mimic each other's appearances but mimicry can also extend to behaviour. For example, say we have two frogs. One is poisonous and uses aposematic (warning) coloration by being bright blue. One is harmless and bright blue. This is a case of Batesian mimicry. But if both frogs are poisonous and bright blue, this is Mullerian mimicry.
Do rabbits mimicry?
no. mimicry is when one organism mimics another to survive. a rabbit mimics the snow, witch is not a living organism.
Is mimicry a noun?
Yes, the word mimicry (mimicries) is a singular, common, abstract noun; a word forthe act or art of copying or imitating closely, often forentertainment; theresemblance of one organism to another or to an object in its surroundings for concealment and protection from predators.
How do you use mimicry in a sentence?
The Viceroy Butterfly uses clever mimicry of the Monarch Butterfly to deter predators.
What is aggressive mimicry?
A form of mimicry in which predator closely resembles another organism on which mimic preys.
Why does the presence of mimicry reflect how interactions shape community structure?
Mimicry limits the ability of predators to find food.
What does mimicry mean in the science term?
In evolutionary terms, mimicry is the similarity of one species to another that provides benefit for one or both species. This can include similarities in things like; appearance, behaviour or scent. An example of this is a harmless butterfly which mimics the patterns of a poisonous butterfly so that predators stay away. This form of mimicry is known as Batesian mimicry.
What is the pattern mimicry?
Mimi can give predators and prey a survival advantage
What is it called when one organism imitates the traits of another?
most do so by colour example: milk snake, has red and black touching coral snake, has red and yellow touching Little rhyme to help remember red and black, your ok jack red and yellow, your a dead fellow
