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?
Identify the interaction used to describe each type of interdependence among organisms. Having too many fish in a pond can limit the amount of food and space available.
How are species introduced to new ecosystems? Check all that apply.
The cheetah population depends on the gazelle population for food.
