Niches and Community Interactions

Why can't two species occupy the same niche and habitat at the same time?

• Because of the interactions that shape the ecosystem.

• They can unless they require different abiotic factors.

• Because of the competitive exclusion principle.

• They can unless they require different biotic factors.

Which of the following is a biological aspect of an organism's niche?

• the water in the area

• the way it gets its food

• the amount of sunlight

• An organism makes "money" by working in its niche.

• A niche is a "company" that the organism has to work in.

• A niche is a "factory" where organisms build things.

• An organism can "make a living" and survive in its niche.
