Ecological dominants are typically the top predators in a community.

Because their absence may have negative repercussions for population control and resource use for the whole community,lions on the African savanna are identified as a keystone species.

A flea is considered to be a predator on a dog.

Keystone species are:

Many plant species produce flowers of a certain color and shape to attract honeybees.These plants produce nectar,and the bees transport pollen from one plant to another while searching for nectar.This is an example of:

The term "niche" is usually limited to a description of the physical surroundings in which a species is normally found.

An interaction in which one species benefits and the other is not affected is classified as:

Two ways that one species obtains its nourishment at the expense of another are predation and ________.

The number of prey species is one of several factors determining the number of predators that can live in an area.

Organisms in communities may be important factors in the evolution/adaptation of other organisms in the community.

Which form of biological succession occurs in an area where most life has been destroyed,but fertile soil remains?

After succession,a stable group of species that persists over long periods is referred to as a:

Generally speaking,the term for the process by which two species drive each other's evolution is:
