1. White-breasted nuthatches and downy woodpeckers both eat insects that hide in the furrows of bark in hardwood trees. The downy woodpecker searches for insects by hunting from the bottom of the tree trunk toward the top, whereas the white-breasted nuthatch searches from the top of the trunk down. These hunting behaviors best illustrate which of the following? Competitive displacement of resources for the downy woodpeckers

Exploitative interaction, resulting in declined diversity

Competitive mimicry that will result in reduced resources

Coordination of resources, allowing for access to both species

2. As prey populations increase slightly in size, predator populations will at first

decrease greatly

decrease slightly

increase greatly

increase slightly
