Yes and No, some seahorses are poisonous to keep their prey away and some seahorses are not poisonous.
Aquatic plants help to oxygenate the water - replacing the oxygen that's used by the fish - and the decaying fish waste.
aquatic plants live in water because they cannot survive on land
well oxygen dissolves in the water and makes it dissolved oxygen and so they still take in regular oxygen just mixed with water
life is not all aquatic some lives are terrestrial and others are aquatic
terrestrial- lives or grows on land
aquatic- lives or grows in water
Advantages:
Sustainable Fishing
Higher yields (no Anaerobic Gill Disease) due to freshwater paths
No waste Food due to auto feeder and Infrared Technology
Each Generation Artificially selected to only obtain fish with highest possible yield and disease resistance, increasing yield.
Can be genetically modified to have a 10 fold size increase, and can be made to grow on less nutrients and be more disease resistant.
- Increased growth of fish in hatcheries, due to artificially fertilizing eggs, leading to higher chance of fertilization, as in the wild only 10% of eggs are fertilized.
Disadvantages
- High doses of antibiotics used, leading to bio-accumulation in humans that consume it
- Indoor Hatcheries lead to bio-accumulation of Heavy metals
- Large amount of freshwater used in indoor hatcheries, which means with out an on-site recyclers process is very expensive
- unknown consequences of genetic engineering
- Outdoor Hatcheries leads to competition between wild fish and farmed fish (even though still in nets, food, oxygen and space is still being consumed)
- Environmental impact of large wastes concentrated in one area
- Easy for disease to spread due to low spatial equality, leading easy transmission from host to host.
- Small spaces leads to fin and tails being damaged due to rubber with nets or walls of hatcheries.
Aquatic plants provide food and habitat for many animals such as fish and waterfowl. They provide soil stability, and keep ponds and lakes from eroding.
Rooted aquatic plants can be found in areas with lower sunlight exposure. This is because the plants are used to having limited light because they're used to being in the water.
If the goldfish is big enough and the guppies small enough, yes the guppies could well be eaten by the goldfish.
Also, guppies should never be with guppies are guppies are tropical fish and goldfish are coldwater fish.
An aquatic plant is a plant that lives in freshwater. Some can live submerged in the water or live floating on the water. Other live on the floor of the pond or lake or wherever it is. They can also live in between drifting. Examples would be lily pads are floating however, aquatic ferns live at the floor. They can live in salt water like the ocean or regular water like a pond or lake.
'A plant that grows partly or wholly in freshwater whether rooted in the mud, as a lotus, or floating without anchorage, as the water hyacinth.' From Answers.com
A marine plant is a plant that lives in seawater.
It means that the plant does not reproduce by means of traditional flowers and seed is not formed within a closed ovary of the flower.
Examples of non-flowering plants are: ferns and mosses which reproduce by means of spores, as well as gymnosperms which produce seed in "naked" ovaries (cones).
Because Hydrilla being an aquatic plant absorbs water from free surface of entire plant body and need not to conduct water through xylem tissue.
An aquatic plant bubbles because it releases oxygen bubbles. The oxygen bubbles float to the surface of the water and get released in to the air.
Sunlight doesn't travel very far through water so a plant needs to be near enough to the surface to photosynthesize.
when an aquatic (water) plant has to adapt to it's environment to survive some examples are: (there are many) adapted coloration to different intensities of light doesn't have the tissue in the stem that strengthens it-is entirely supported by water bladderwort can trap its food via. a small "bladder" underneath it that traps small aquatic animals stronger anchoring roots hope this helps :)
Feet. They crawled from land to water.
Huge leaves with humongous surface area.
In freshwater pollutant testing, various species of Daphnia are used.
(Daphnia magna and Daphnia pulex being most common). Specimens are added to the sample, and then the amount of time until death is one of the many ways they are used to identify the presence of and concentrations of various chemicals. These results are compared with results of similar tests in a lab environment.
