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.
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.
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?
If the triggerfish population increases, what would happen to the small-fish population?
