<h2>Answer:</h2>

A heterotroph is dependent on autotroph or other heterotroph for its energy whereas Autotrophs are dependent on Sun for their energy.

<h2>Explanation:</h2>

Based upon the nutrition mode, the living organisms are classified as autotrophs and heterotrophs. The organism which has the ability to prepare its own food are called heterotrophs, whereas the organism which is dependent on autotrophs and other animals are called as heterotrophs.

Basically plant are called as autotrophs as they prepare their own food with help of sunlight, and water due to the presence of chlorophyll by process called photosynthesis.

Animals and human beings are called as heterotrophs as they don't have ability to prepare their own food and in turn is dependent on plant and other animals.

In an ecosystem, why can only one species fill an ecological niche? (Site 1)

Anastaziya [24]

Answer:

Only one species can fill an ecological niche because each niche is destined exclusively for each species, since its structure, physiology and behavior determine it.

Explanation:

An ecological niche is the way in which each species relates to its environment, to other species and takes advantage of the resources available for its development, being an exclusive and individual characteristic of that species.

The ecological niche is a concept that many consider abstract, since it is unique for a species. Each species has a physical structure, functioning and behavior that differentiates it from the others, which leads it to occupy a certain place within an ecosystem, which would be its ecological niche.
