Question

The role of organism in ecological system is known as:

A. Habitat

B. Herbivory

C. Niche

D. Interaction

Answer 1

Hint: Each Organism plays a role in its ecosystem. The term niche is used to describe the role an organism or population plays within its community or ecosystem. It encompasses all relationships that the organism (or population) has with its environment and with other organisms and populations in its environment.

Complete answer:

In order to answer this question let us known about different terms given:

• Habitat is the type of natural environment in which an organism lives.

• Herbivory is a practice of organisms wherein they only consume plants and not meet.

• Niche is the role of a species in a community, including the type of food it eats, where it lives and how it reproduces etc.

• Interaction is communication or direct involvement with something. The Organism does not have a role in it.

Thus, the correct answer is option (C), i.e., Niche.

Additional information:

In ecology, a niche is  the match of a species to a specific environmental condition. It describes how an organism or population responds to the distribution of resources and competitors and how it in turn alters those same factors. For example, a garden spider is a predator that hunts for prey among plants, while an oak tree  grows to dominate a forest canopy, turning sunlight into food. The role that species plays is called its ecological niche. It includes more than what an organism eats or where it lives.

Note: Based on the interactions of species with the physical and biological world, niches  are of three types that are spatial or habitat niche, trophic niche and multi dimensional niche. Thus, the concept of ecological niche is widely used by the ecologists to understand how the communities are related to their specific environmental conditions.
