The role an organism fulfills in the place where it lives is called what?

• A. Niche
• B. Population
• C. Habitat
• D. Environment

Answer: (A)

The main idea here is what ecologists call an organism’s niche—the role it plays in its ecosystem and how it makes a living there. A niche includes what the organism eats, how it obtains energy, how it interacts with other organisms (like predators, prey, or competitors), when and where it does these things, and how it affects its surroundings. This is the job or function the organism has in that specific place.

Habitat is the physical place where an organism lives, like a forest, a pond, or a desert. Environment refers to the overall surroundings and conditions, including both living and nonliving factors. Population means the group of individuals of the same species living in an area.
