<h3>What is Niche?</h3>
An organism's functional place in an ecosystem is known as its niche.
The biotic elements, which include living components like animals, plants, and fungus, as well as abiotic factors, influence the niche, which is more precisely referred to as the "ecological niche". Abiotic variables are the non-living elements of the environment, including the availability of water, sunlight, and other resources like food and other nutrients.
The distribution and abundance of these elements, as well as how a creature interacts with and changes them, determine its niche within an ecosystem. For instance, when resources are plentiful, a population increases, yet by doing so, the population increases the amount of resources available to predators.
