Several species of warblers can live in the same spruce tree ONLY because they

• have different habitats within the tree.

• don’t eat food from the tree.

• occupy different niches within the tree.

• can find different temperatures within the tree.

When two species of cattails are grown together, they grow at different water depths and coexist.  When grown alone, they grow at similar water depths.  Which of the following is best demonstrated by the data?

• natural selection

• character displacement

• resource partitioning

• ecological succession

Which of the following populations is most likely to go extinct?

• a very small population in an unstable environment

• a moderate-sized population of r strategists

• a large population with lots of genetic variability

• all would be equally likely to go extinct

A good way to estimate the population size.

• mark-recapture

• count everyone of them

• satellites

• cameras

How many types of survivorship curves are there?

• 1

• 2

• 3

• 4

In the woods, there are hawks and robins. They both try to occupy the same niche by competing for worms as the only source of food in that same area at that same time. The hawks outcompete the robins, and the robins are forced to leave that area. This is an example of:

• Mutualism

• The competitive exclusion principle

• Commensalism

• Neutralism
