Food provides animals with the materials and energy they need for growth, warmth, and motion. Plants get material for growth mostly from air and water, and obtain energy from sunlight.

Producers provide food to consumers because ―

• many animals prefer eating plants to eating meat
• plants can easily make food from soil and water
• animals cannot produce their own food
• plants are more abundant in ecosystems

Brown trout consume (eat) more tadpoles when the fly larvae reduce in number (decrease).  This proves...

• Diversity increases as organisms decrease
• Losing an animal is good for ecosystems
• Changes in ecosystems create new organisms

In this tundra food web, if grasses were removed what would happen to the sustainability of the ecosystem?

• There would be an overpopulation of arctic hares and lemmings.
• Polar bears would move to a new ecosystem
• The ecosystem would collapse because it lost its main producer
• Wildflowers would die out from the ecosystem

Define ecosystem stability

• a healthy ecosystem with factors that stay mostly stable

• a healthy ecosystem with factors that fluctuate between great and terrible

• an unhealthy ecosystem with factors that stay mostly stable

• an unhealthy ecosystem with factors that fluctuate between great and terrible

A rain forest ecosystem is characterized by high biodiversity and a warm/rainy climate. How might this impact the ecosystem's sustainability if the ecosystem is damaged by a catastrophic event?

• The ecosystem, because it has few plant and animal species, will experience low sustainability, not allowing it to recover

• The ecosystem, because it has many plant and animal species, will experience high sustainability, allowing it to recover

• Biodiversity does not have an impact on an ecosystem's sustainability
