Chapter 5 Review

A factory releasing pollutants into a watershed would have a negative effect on...

• the amount of space for crops

• the amount of rainfall

• the direction of the flow of a river

• the local pond organisms

The drink mix in our watershed model represented

• pollution

• surface runoff

• conservation of water

• condensation of water vapor

Pioneer species are involved in the first stages of succession, and climax communities are involved in the final stage.

• True

• False

Weeds and grasses grow before other plants because

• they can grow in nutrient poor soil

• they need a lot of water and the soil has water

• they grow well in the shade

• they need the trees to provide roots

The ecosystem with the least sustainability will be the one that

• has a moderate temperature and moderate amount of rainfall

• has limited plants and animals

• has the greatest biodiversity

• has many producers and consumers

The habitat with the most sustainability is the one with

• the fewest animals

• the most rainfall

• the greatest biodiversity

• the greatest number of a single species of grass

Horned lizards have thick skin to prevent water loss and they burrow to escape the heat. Which biome would you find them?

• tundra

• savannah

• boreal forest

• desert

Most desert plants ave spines. How does this adaptation help them survive in a harsh environment?

• the spines capture water

• the spines will make it rain

• the spines make it colder

• the spines will protect the plant from animals that want to eat it

You observe earthworms in a microhabitat in your schoolyard. All of the following are ways that this microhabitat support the organisms that live in it except -

• it has oxygen that the plants produce for the worms to breath

• it has carbon dioxide that the worms release for the plants to absorb

• it has rock that the worms eat for energy

• it has a source of light for the plants to make food

The negative effects do tornadoes have on an ecosystem?

• rising flood waters that destroy crops

• high wind speeds that uproot trees

• extreme cold that causes ice

• high winds that cause wide spread fires
