Ecology: Resource Partitioning and Habitat Partitioning

Play an AI-generated podcast conversation about this lesson

What is the main purpose of resource partitioning in an ecosystem?

To increase the population of keystone species

To promote interspecific competition for limited resources

To divide resources to avoid interspecific competition for limited resources (correct)

To reduce the number of species in an ecosystem

What is an example of habitat partitioning in anole lizard species found on the island of Puerto Rico?

Different species of lizards have different lengths of proboscis

Different species of lizards occupy different areas of habitat such as forest floors and trees (correct)

Different species of lizards consume different parts of a food resource

Different species of lizards live in different ecosystems

What is the characteristic of keystone species in an ecosystem?

They only influence the population of other species in an ecosystem

They are not critical for the overall structure and function of an ecosystem

They have a low impact on the ecosystem relative to their population

They have a high impact on the ecosystem relative to their population (correct)
