Which statement correctly describes biogeochemical cycles?
- They show how matter moves through both biotic and abiotic portions of an ecosystem.
- They show how matter and energy move between organisms and the earth.
- They show how energy moves through the earth's hydrosphere, lithosphere, and atmosphere.
- They show how matter and energy flow between the earth and the sun.

The carbon and nitrogen cycles each include a step in which an element is "fixed." What does this mean?
- It is taken from the atmosphere and turned into a usable form.
- It is washed into a larger body of water.
- It is released from dead plant and animal tissue by decomposers.
- It is broken down from exposed rocks by weather.
One fixation happens during photosynthesis; the other happens in the bacteria in roots of some plants.
