Habitat and Niche

Habitat and Niche

Key Concept: Every organism has a habitat and a niche. 

Multiple Choice

Are these frogs experiencing competitive exclusion? Explain.

• This is an example of competitive exclusion because the frogs are in the same community, competing for the same limited resources.

• This is not an example of competitive exclusion because the frogs are not in the same community, competing for the same limited resources.

• This is not an example of competitive exclusion because the frogs are different colors.

• This is not an example of competitive exclusion because the frogs have adapted to share the resources.

Multiple Choice

• home; habitat

• habitat; abiotic factors

• abiotic factors; biotic factors

• habitat; ecological niche

Multiple Choice

What are the three parts of an organism’s ecological niche?

• Three parts of a niche include food type, abiotic conditions, and behavior.

• Three parts of a niche include food type, biotic conditions, and behavior.

• Three parts of a niche include shelters, abiotic conditions, and behavior.

• Three parts of a niche include food type, abiotic conditions, and biotic factors.

Multiple Choice

What does the principle of competitive exclusion say will happen when two species compete for the same resource?

• They will share the food equally

• One species will always eat first the the others have to wait their turn.

• One species will be better suited to the niche and the other species will either be pushed into another niche or become extinct.

• In a year they will adapt and become more competitive, and retake their territory.
