Crash Course: Classmate Edition: Energy cycles

Goal: Learn how matter/energy cycles through ecosystems.

The Cycles

• There are 3 different cycles.• Water Cycle• Carbon Cycle• Nitrogen Cycle

Water Cycle• The water cycle is series of gases (water vapor), liquids (water), and solids (ice).• It starts as water on the Earth’s surface where it evaporates.• Then it turns into vapor which is the rain in the clouds. Then when it precipitates the

water falls as rain, snow, hail or sleet onto the land and oceans. • Then it repeats, thus the water cycle.

Carbon Cycle• The carbon cycle is where oxygen and carbon dioxide are transformed.• Carbon can be transformed from burning fossil fuels, photosynthesis and

respiration.

Nitrogen Cycle• The nitrogen cycle is when nitrogen is released from objects.• The nitrogen in dead animals, soil, and dead plants is released by decomposition

by decomposers and bacteria.• Plants take up the nitrogen from the soil and animals eat the plants.• Animals use nitrogen in DNA.• Nitrogen is also released into the atmosphere when lightning strikes.
