Exam 14: Predation

A true predator is a species that

When predators come together in areas of high prey density,it is referred to as

If you are stranded on a desert island,which prey should you avoid consuming?

Which of the following is functionally a true predator?

Which of the following is an example of cryptic coloration?

Quantitative inhibitors in plants are toxic secondary compounds,often causing herbivores to avoid their consumption.

In a graph that plots prey population (Nprey)on the x-axis against the number of predator offspring produced per unit of time on the y-axis,the slope represents the

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

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

One explanation for the shape of the Type II functional response is that predators develop a search image for prey after they have encountered them.

Pursuit hunting requires minimal search time.

All three of these species are harmful.This is an example of

The increase in a predator's reproduction in response to an increase in the consumption of prey is known as the predator's ________ response.

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

________ is the consumption of one living organism by another.

This figure shows that

Carnivores can have an indirect,positive effect on plants by reducing populations of herbivores.

When a predator drives down a prey population to a low abundance,it will often

________ is a deliberate form of hunting with a quick attack.

The response of a predator's consumption rate to prey density is a key factor as to whether a predator can regulate a prey population.
