Question 37

The small insectivorous birds Creepers and Nuthatches both feed on the trunks of trees of the same species in the same mixed conifer/broadleaf forests, but one hunts exclusively moving up the trunk and the other moving down the trunk. This is an example of resource partitioning.

True

False

Question 38

Counter-current gas exchange is analogous in avian reptiles (birds) and ray-finned fishes (actinopterygii).

True

False

Answer 1

1. The small insectivorous birds Creepers and Nuthatches both feed on the trunks of trees of the same species in the same mixed conifer/broadleaf forests, but one hunts exclusively moving up the trunk and the other moving down the trunk. This is an example of resource partitioning. This statement is TRUE. This method of division of resources among closely-related species is not only beneficial to both but also keeps one species from being punished to extinction.
2. Counter-current gas exchange is analogous in avian reptiles (birds) and ray-finned fishes (actinopterygii). This statement is FALSE.
