The organisms in an ecosystem interact in many ways to survive. For example, a rosebush, aphids, beetles, spiders, and orioles all interact in a rosebush ecosystem. The diagram below shows how these organisms interact in a partial food web.

Remora fish can attach themselves to larger aquatic animals, such as whales. When the whales eat, the fish detach themselves and eat leftover scraps of food. These fish do not harm or help the whales.
What is the ecological relationship between the remora fish and the whales?

competition

commensalism

parasitism

predation

Which of the following statements best describes how an increase in the size of a mammal population could be related to a large surplus of food?

With an abundance of food, adults now outnumber predators.

With enough to eat, more females are healthy and the birth rate increases.

Since there is no competition for food, most individuals develop mutualistic relationships.

Since they no longer need to hunt, some males increase their territories and cause other males to move away.
