Identify the key term described. The relationship that results when organisms in an environment rely on each other for resources
Identify the interaction used to describe each type of interdependence among organisms. The red-billed oxpecker (a bird) eats ticks off the fur of an impala (a type of antelope). The oxpecker receives food and removes the ticks from the impala.
Given the relationships identified above, determine what would happen to the populations under the following circumstances. If the Impala population decreases, what would happen to the oxpecker population?

Both species benefit.
Tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human.
A change in one species that results from a change in another species with which it interacts
Titan triggerfish move large rocks in the ocean to find food. In return, smaller fish are able to eat because the moved rocks expose food. The titan triggerfish are not affected.
If the triggerfish population increases, what would happen to the small-fish population?
