ivanzaharov [21]

Answer:

E) ecological niche

Explanation:

Every species on the planet, be it a bacteria, animal, or a plant has its own ecological niche. Basically, the ecological niche is the position and role that an organism is occupying in the environment. Further, this means that it is a combination of all the activities of the organism, how it uses the biotic and abiotic factors in the environment it leaves, how it finds food and how it feeds, its shelter, reproduction, the manner in which it survives. All of that sums up the species and its role in the environment, thus its ecological niche. There are countless ecological niches, as there are millions of different species, all of which have their own way of living, feeding, reproducing, interactions with the biotic and abiotic factors, resulting in numerous unique ecological niches.
