This tortoise is eating cactus on a sunny day. Is carbon moving into the air, moving out of the air, or both?

• Carbon is not moving into the air; it is only moving out of the air.

• With this information, there is no way to know for sure.

What will happen if a drought causes the population of grass to decrease?

• The population of decomposers will decrease because there are less organisms dying.

• The population of owls will not be affected because they are predators who do not eat grass.

• The population of mice will decrease because there will be less food available due to the drought.

• The population of grasshoppers will increase because they will find a different, better food source.
