In a forest ecosystem, wolves prey on deer, and deer browse on young saplings. If a disease dramatically reduces the wolf population, what is a likely consequence of this trophic cascade?

The deer population will also decrease.

The number of young saplings will decrease.

The wolf population will quickly recover on its own.

The population of birds in the forest will increase.

If a new disease caused a sharp decline in the Moon Jelly population, what would be the most probable immediate effect on the other populations mentioned?

The zooplankton population would increase due to reduced predation.

The Walleye Pollock population would also decline due to the disease.

The zooplankton population would decrease.

The Walleye Pollock population would immediately increase to fill the niche.

Both populations would increase as they switch to a new food source.

The Moon Jelly population would decline, but the Pollock would be unaffected.

Both populations would face stress and likely decline due to food scarcity.

The Pollock would begin eating the Moon Jellies to survive.

When a single species' population grows uncontrollably without affecting other species.

The process where changes in the population of a species at one trophic level cause a series of effects through other levels of the food web.

A direct competition for territory between two predator species.

The seasonal migration of a species from one ecosystem to another.
