Crash Course: Classmate Edition: Energy cycles

1. Crash Course: Classmate Edition: Energy cycles Goal: Learn how matter/energy cycles through ecosystems.

2. The Cycles • There are 3 different cycles. • Water Cycle • Carbon Cycle • Nitrogen Cycle

3. 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.

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

5. 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.

7. TEST TIME? • In the water cycle what is the process liquid goes through to become a gas? • What is one of the ways that nitrogen is fixed so that organisms may use it? • How does a plant get carbon dioxide from living things? • What is the process in which carbon in fossil fuel is return to an ecosystem? • What biome contains the earth’s most carbon? A. Ocean B. Taiga C. Grassland
