Exam 15: Predation

According to the Red Queen hypothesis,

A parasitoid

A plant may be able to compensate for the loss of leaves by increasing the rate of ________ in the remaining leaves.

Herbivory does not affect a plant's ability to survive.

Some plants are able to attract beneficial insects that act as predators on the herbivores of that plant.

Which of the following is considered a nonlethal effect of predation?

Some animals acquire their toxic chemical compounds from plants that they consume.

Under the marginal value theorem,when patch quality is equal,what other factor is expected to influence the time a predator spends foraging in a patch?

The concept of ________ energy is the basis for models of optimal foraging.

A type III functional response is the most commonly reported for predators.

The net outcome of predator-prey interactions in the basic Lotka-Volterra models is that

A true predator is a species that

Grazers and browsers are true predators.

Most animals live in a relatively homogeneous environment in which the spatial density of prey does not vary much.

As prey species evolve more effective means to avoid being caught,predators evolve more effective means to capture them.

Pursuit hunting requires minimal search time.

If defoliation of trees is complete,the leaves that regrow are often larger than the original leaves.

It is difficult to quantify the consequences of a specific behavioral choice on the probability of survivorship and reproduction.

Animals that are boldly colored or patterned to warn potential predators possess warning coloration or ________.

The movement of predators into areas of high prey density is a type of numerical response referred to as a(n)________ response.
