Question

1. in madagascar, several species of lemur eat bamboo, but each species specializes in one part of the bamboo—one species eats mature bamboo stalks, one species eats bamboo shoots, and one species eats leaves. this is an example of

resource partitioning.
speciation.
competition.
niche partitioning.

Explanation:

Resource partitioning refers to the division of limited resources by species to help avoid competition in an ecological niche. In this case, different lemur species are dividing the bamboo (a resource) into different parts (stalks, shoots, leaves) to consume. Speciation is the formation of new species. Competition would imply more direct struggle over the same resource part. Niche partitioning is a broader concept that can include resource partitioning but also other aspects like spatial or temporal partitioning. Here, the key is the division of the resource (bamboo) into parts, which is resource partitioning.

Answer:

resource partitioning.
