Cycles in Ecosystems

All living things use energy and release gas as a waste product. What cycle explains the curculation of these gases?

• Water Cycle

• Oxygen-Carbon cycle

• Nitrogen cycle

The ___________ cycle is a continuous circualtion between the soil, organisms, and the air.

How do animals get nitrogen that is stored in the soil?

• They are unable to

• Bacteria change the nitrogen into a gas that the animals can breath

• Plants absorb the nitrogen from the soil and animals can eat the plants

• Animals can eat the soil and absorb the nitrogen through their digestive system

We've learned that plants use sunlight, water, and carbon dioxide to make their own food and release oxygen. How can animals complete the oxygen-carbon cycle?

• Animals take in the oxygen, but do not release gas as they use energy

• Animals take in carbon dioxide and use it to make food

• Animals take in oxygen and release nitrogen as waste

• Animals take in oxygen and as they use energy, carbon dioxide is released as waste.
