whats a species niche?

Question

yeahhh...

Answer 1

A niche would be the sum of all the species' roles/function in the ecosystem. It's not just the species' "profession"; the niche includes the species' address, community involvement etc.. You can imagine how difficult it is to pin this one; scientists/people can only take describe a small aspect of this totality at a time. I remember reading the niche defined as a "multidimensional hypervolume".

Answer 2

Many populations of animals can live in the same area because each species fills a specific role in the community. This role is called a niche. What an animal eats, and where it eats are also part of its niche. Giraffes can live in the same area as gazelles because they eat different plants and don't compete with each other. Dung beetles bury the feces of these animals and lay their eggs in it. The hatching grubs feed on the feces. The buried feces also fertilize plants, which in turn feeds the gazelle and giraffe. Each plant and animal has its own niche in the ecological community, and is important in some way to the survival of the other.

There are limiting factors in an environment which determine whether an organism can live in a particular environment. Limiting factors on land include temperature, water, light, competition, and soil. Every organism needs certain requirements for its survival.

Most organisms can survive if the temperature is within a certain range. The freezing condition of the tundra has resulted in animals with thick fur, lots of body fat, and small ears. Animals in a desert will have large ears, like the elephant, to disperse body heat. Animals in the desert have developed adaptations to keep sand out of their ears and nose.

The amounts of sunlight and rainfall are also limiting factors for both plants and animals. Both affect plant growth. Which plants grow in a biome determines which animals inhabit that biome. For example, grey squirrels, which feed on nuts, are found in woodlands, but not in deserts where nuts aren't found.

Competition results when two different species try to fill the same niche. This usually results in one species displacing another species, or the extinction of one of the species.

Answer 3

A niche is where a species fits right in. It's a place where the conditions are ideal for its thriving, and (usually) where it also helps the conditions there in return.

That's where the saying "carved out a niche for himself" comes from.

Answer 4

Where they fit in well and like what they are doing.
