09.22.17 How is carbon taken out of the atmosphere? I can describe and depict nutrient cycles.

1. Check Packet Assignment 2. Cycles Key Details 3. Cycle Drawings

Water Cycle Liquid water returns to the atmosphere through evaporation and transpiration. Condensation is when water vapor becomes liquid again and returns to Earth from precipitation

When water returns to the ground from the atmosphere, it is called A: Evaporation B: Condensation C: Precipitation D: Transpiration E: All of the above are involved in water leaving the atmosphere

Nitrogen Cycle Needed for plants to build cells Cycled through air by nitrogen fixing bacteria Returned to soil from animal waste, animals dying

The most important aspect of the nitrogen cycle is: A: Provides fresh nitrogen for the air B: Without it plants would not be able to grow C: Helps with the water cycle D: Animals need nitrogen to eat E: All of the above

Carbon Cycle Carbon dioxide cycles through plants and animals Plants use CO2 in photosynthesis and give off O2 Animals use O2 and give off CO2 Reduction of plants, and increased pollution increases carbon in the atmosphere (global warming)

The carbon cycle is important because: A: Plants need it do photosynthesis B: Animals need the carbon cycle for breathing C: Global warming is affected by the amount of carbon in the atmosphere D: Plants and animals use each other’s products E: All of the above are part of the carbon cycle

Use your notes, packet and book to help! Due Monday Now – Use the text to draw the carbon cycle and either the water or nitrogen cycle. *** Include at least 7 labels in each cycle. Use your notes, packet and book to help! Due Monday The Carbon Cycle: Draw and label the path of Carbon through the environment The water cycle: Draw and label the path of water through the environment The Nitrogen Cycle: Draw and label the path of Nitrogen through the environment
