• Consumer

• Heterotroph

• Producer

• Predator

If producers in an ecosystem have 10,000 kilocalories of energy, how much energy would be stored by the primary consumers?

• 100 kilocalories

• 1,000 kilocalories

• 10,000 kilocalories

• 100,000 kilocalories

What is a food web made up of?

• A single food chain

• Only producers and decomposers

• Multiple interacting food chains

• Only predators and prey

What is biodiversity?

• The total number of predators in an ecosystem.

• The variety of all types of organisms living in a given area.

• The amount of energy transferred between trophic levels.

• The process of organisms making their own food.
