Select one:

Marine ecosystems serve as vacation destinations.

Marine ecosystems are home to algae and other photosynthetic organisms.

Marine ecosystems store large amounts of carbon.

Marine ecosystems are a source of fish and seafood.

There would be few species of insects.

The insect populations would be small.

The insects would be living in few habitats.

Select one:

species diversity.

genetic diversity.

type diversity.

ecosystem diversity.
6.Which statement about the impact of biodiversity loss is FALSE?
Select one:

As biodiversity is lost, humans lose ways to get clean water.

As biodiversity is lost, animals in ecosystems lose their homes, but humans are not affected.

As biodiversity is lost, humans lose access to foods and medicines.

As biodiversity is lost, ecosystems become more likely to break down.
7.A town is in a hilly area with rich forests. People of the town harvest timber and sell it. Over time, parts of the hills become barren.

What are some risks caused by this?
Choose all that apply:

The town will have problems finding fuel for the winter.

There may be more landslides.

The air quality of the town may get worse.

There may not be enough timber for future generations.
8.Which statement accurately describes a benefit to humans from ecosystems with high biodiversity?
Select one:

Ecosystems with high biodiversity are less likely to attract people who like to hike, camp, and fish.

Many species of plants produce chemical compounds that could be used to treat diseases.

Natural environments provide more food than controlled environments like farms.

Living in natural environments make people more resistant to diseases.
9.Wetlands are ecosystems that form around rivers. A city on a river relies on the river for its water. The city has many wetlands upstream. Some people get fish and a variety of other animals from the wetlands.

What will be some of the effects of removing these wetlands and building farms in their place?
Choose all that apply:

The water quality of the river will drop.

People will have a fewer options for food.

The water quality of the river will get better.

People will have more food.
