Ecology Review 2 Quizziz

Many years ago, a volcanic eruption killed many plants and animals on an island. Today the island looks much as it did before the eruption. Which statemnt is the best possbile explanantion for this?

• Altered ecosystems regain stability through the evolution of new plant species

• Destroyed environments can recover as a result of the process of ecological succession.

• Geographic barriers prevent the migration of animals to island habitats

• Destroyed ecosystems always return to their original state

A fire burns an oak forest down to bare ground. Over the next 150 years, if the climate remains constant, this area will most likely

• remain bare ground

• return to an oak forest

• become a rain forest

• become a wetland

What impact do the amounts of available energy, water, and oxygen have on an ecosystem?

• They act as limiting factors

• They are used as nutrients

• They recycle the residue of dead organisms

• They control environmental temperature

As succession proceeds from a shrub community to a forest community, the shrub community modifies its environment, eventually making it

• more favorable for itself and less favorable for the forest community

• more favorable for itself and more favorable for the forest community

• less favorable for itself and more favorable for the forest community

• less favorable for itself and less favorable for the forest community

Nutritional relationships between organisms are shown in the diagram below. The mouse population would most likely decrease if there were

• an increase in the frog and tree populations

• a decrease in the snake and hawk populations

• an increase in the number of decomposers in the area

• a decrease in the amount of available sunlight

In the diagram below, what does X most likely represent?
