What else can I help you with?
How is the size of an organism related to its position in a food chain?
Generally, larger organisms are higher up in the food chain because they are apex predators that predate on smaller organisms. As you move up the food chain, energy is transferred and stored, so larger organisms can sustain themselves by consuming a larger quantity of smaller organisms. Larger organisms also usually have fewer natural predators to keep their populations in check.
Similarities of human and dog digestive system?
Both species have the same organs as the other in their digestive system: mouth, esophagus, stomach (in cows, the part of the four-chambered stomach that have similar digestive enzymes to a human's is called the Abomasum), liver, spleen, pancreas, large and small intestines, colon, rectum, anus, etc.
Increasing concentrations of toxins in organisms as you move up the food chain is called?
biomagnification. This process occurs when toxins accumulate in organisms at higher trophic levels due to the consumption of contaminated prey or food sources. Biomagnification can have harmful effects on top predators in the ecosystem.
How are organisims are classified from simple to complex?
Organisms are classified as simple if they only have one cell such as bacteria, and complex organisms have multiple cells that function together to keep the organism alive and maintai homeostasis.
As ddt moves up the trophic levels in food chains its concentration?
increases. This is known as biomagnification, where organisms higher up in the food chain accumulate higher levels of DDT due to consuming prey that have ingested or absorbed the chemical. This can lead to harmful effects on top predators due to the higher concentrations of DDT in their bodies.
When would have a greater variety of organisms a phylum or a family?
A phylum would have a greater variety of organisms compared to a family. Phylum is a higher taxonomic rank that includes a wide range of organisms with more characteristics in common, while a family is a lower taxonomic rank that includes closely related species within a particular genus.
Is bioaccumulation a noun?
Yes, bioaccumulation is a noun. It refers to the gradual accumulation of substances, such as pesticides or heavy metals, in living organisms over time, resulting in higher concentrations in the organisms than in the surrounding environment.
What characteristics that all organisms share?
Cellular activities such as aqueous absorption of raw materials are shared by all living organisms. They are created, grow, reproduce, die, and are consumed or decompose. Other than that, there are no common characteristics between bacteria, complex plants, and higher animals.
Which level of classification contains organisms that are most closely related order or family?
Organisms within the same family are more closely related than those within the same order. Family is a higher classification level than order, so organisms within the same family share more recent common ancestry.
Why are there fewer organisms higher on the energy pyramid?
There are fewer organisms higher on the energy pyramid because energy is lost as it moves up the food chain through consumption and metabolism. This results in less energy available to support higher trophic levels, leading to a decrease in the number of organisms at each successive higher level.
Why do endothermic organisms have a higher BMR than ectotermic organisms?
Endothermic organisms have a higher Basal Metabolic Rate (BMR) because they rely on internal heat production to maintain their body temperature. This requires more energy expenditure compared to ectothermic organisms, which rely on external sources of heat to regulate their body temperature. Additionally, endothermic organisms have higher metabolic demands due to their higher activity levels.
Why are higher levels of biodiversity good for ecosystem stability?
The higher the biodiversity, the higher the number of species, and the lower the rate of extinction. A decrease in biodiversity means a single species will become extinct and this will have a negative impact on other organisms for all organisms in an ecosystem are connected.
What happens when the number of organisms is an environment is higher than the carrying capacity?
then the organisms must compete for living space The population will decrease.
What is the relationship between family, genus, and species in the classification of organisms?
In the classification of organisms, family is a higher taxonomic rank than genus, and genus is a higher rank than species. Organisms that belong to the same genus are more closely related than those in the same family, and organisms in the same species are the most closely related.
Why mycorrhizae is important for higher plant?
Because mycorrhizae are symbiotic micro-organisms, providing nirogen to the higher plants by nitrification.
Is a rose eukryotic or prokaryotic?
All the higher organisms are Eukaryotes, so do ROSE
Are there differences between major groups of organisms to how fast they respire?
Yes, there are differences in respiration rates among major groups of organisms. For example, mammals generally have higher respiration rates compared to plants or reptiles. This is influenced by factors such as metabolic rate, body size, and environmental conditions.
