The grasshoppers would thrive as the plants become more resilient.

c)

The plants would grow stronger, providing more food for the grasshoppers.

d)

The grasshoppers would migrate to find better food sources in other areas.

4.

In a grassland ecosystem, lions eat gazelle and gazelle eat grass. If there were more lions what would happen to the grass population and why?

a)

The grass population would decrease because there would be more gazelle

The grass population would increase because there would be less gazelle to eat it.

c)

5.

A fish tank is in a classroom. The students make the AC very cold. This makes the water in the tank colder, after a few days, the tropical fish in the tank die.

A change in an abiotic factor (water temperature) affected biotic factors (fish populations).

b)

A change in a biotic factor (fish) caused the water temperature to decrease.

c)

A change in decomposers caused producers to disappear.

d)

A change in predators caused more oxygen in the fish tank.

6.

8.

A local government wants to protect a forest that is home to many species, so they plant new native trees in empty areas of the forest, make clear rules that limit hunting of top predators and work with nearby farmers to reduce pollution and soil erosion flowing into the forest streams.

What is a strength of this solution?

a)

It leads to higher pollution levels in the streams.

b)

It promotes biodiversity and ecological balance by protecting the trees so more animals have a home and limiting hunting so that animals do not become extinct.

c)

It encourages overhunting of local wildlife.

d)

It increases deforestation and habitat loss.

9.

A local government wants to protect a forest that is home to many species, so they plant new native trees in empty areas of the forest, make clear rules that limit hunting of top predators and work with nearby farmers to reduce pollution and soil erosion flowing into the forest streams.

What is a possible challenge with this solution?

a)

Resistance from local hunters and farmers to new regulations and practices.

b)

Limited access to forest areas for recreational activities.

c)

Higher costs for farmers to implement new practices.

d)

Increased wildlife poaching due to lack of enforcement.

10.

A local government wants to protect a forest that is home to many species, so they plant new native trees in empty areas of the forest, make clear rules that limit hunting of top predators and work with nearby farmers to reduce pollution and soil erosion flowing into the forest streams.

What is one way to improve this solution?

a)

Encourage more farming near the forest edges.

b)

Plant non-native trees to diversify the forest.

c)

Increase the number of hunting permits issued.
