Cycles Review

Why are cycles in ecosystems important?

• They explain how energy moves through trophic levels of an ecosystem.

• They describe how the adaptations of organisms change based on environmental pressures.

• They chart how biotic changes destroy unstable ecosystems.

• They show how certain elements and matter move through the environment and are continually used and recycled.

What must happen for organisms to be able to use nitrogen?

• Nitrogen-fixing bacteria must convert nitrogen into a form for plants to absorb.

• Nitrogen must be converted to oxygen for organisms to use the gas.

• Denitrification makes nitrogen usable by plants.

• Nitrogen must be dissolved in water to be used.
