Where should students place a water collection container to determine the effect of runoff from the football field? Options: In the ground near the sprinkler, In a gutter that flows to a nearby pond, Directly under the sprinkler, Suspended directly above the sprinkler.

Back

In a gutter that flows to a nearby pond

If the grasses in each ecosystem are attacked or killed by a disease, which ecosystem will most likely survive? Options: The prairie ecosystem, because fewer organisms eat grass; The tundra ecosystem, because there is a variety of producers; The prairie ecosystem, because there are fewer top predators; The tundra ecosystem, because it has more herbivores.

Back

The tundra ecosystem, because there is a variety of producers.

Front

How does biodiversity contribute to the sustainability of an ecosystem?

Back

A variety of plant and animal species allows for more survivors of a natural disaster.

Front

Which ecosystem would be most sustainable if all the grasses died from severe drought? Options: The forest ecosystem is most sustainable because there are more top predators, The grassland is most sustainable because most of the animals can eat other organisms, The forest ecosystem is most sustainable because most of the animals can eat other organisms, The grassland ecosystem is most sustainable because there is less competition for food.

Back

The forest ecosystem is most sustainable because most of the animals can eat other organisms

Why is biodiversity important in an ecosystem?

Back

It leads to sustainability, which enables it to withstand a disturbance
