Identify the interaction described below. One organism benefits while the other is killed.
Two species need the same resource, which is limited.
An owl catches a mouse and eats it for dinner.

Remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals.

Identify the interaction described. One species benefits and the other species is neither harmed nor helped.
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?
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.
The cheetah population depends on the gazelle population for food.
Both species benefit.
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.
Given the relationships identified above, determine what would happen to the populations under the following circumstances. If the cheetah population decreases, what would happen to the gazelle population?
One species benefits and the other species is harmed.
Humans release carbon dioxide that plants need; plants provide oxygen that humans need.
If the triggerfish population increases, what would happen to the small-fish population?
