Question

A woodpecker drills a hole into a tree and then abandons it. Another species of bird then uses this hole to build their nest. The woodpecker is:

a) A pest
b) A keystone species
c) An allogenic ecosystem engineer
d) An autogenic ecosystem engineer

Answer 1

The woodpecker in this scenario is an autogenic ecosystem engineer, meaning it creates or modifies its own habitat and benefits other species.

Step-by-step explanation:

The woodpecker in this scenario is classified as an autogenic ecosystem engineer. An autogenic ecosystem engineer is a species that creates or modifies its own habitat, which then benefits other species. In this case, the woodpecker drills a hole into a tree, creating a cavity that another species of bird uses for nesting.
