The Carbon Cycle The Carbon Cycle The Carbon Cycle * Carbon is an element found in all living things. Four ways carbon is recycled is described here. The oxygen cycle can be thought of having two sides or parts. One is photosynthesis during which green plants take in carbon dioxide and water and give off oxygen as waste. and the other is respiration which uses oxygen and give off carbon dioxide and water as waste. Oxygen Carbon Dioxide Sugar Water Water Carbon Dioxide – Oxygen Cycle Sugar 2. Carbon is also stored in dead organisms. Bacteria and fungi decompose dead organisms and help return carbon to the atmosphere. 3. Additionally, carbon can be trapped in fossils and limestone deposits for millions of years. It is slowly released through the process of weathering. 4. Fossil fuels also store carbon for long periods of time. The carbon atoms are only released when these fuels are burned. Abiotic factors help to determine what plants and animals can live in a certain environment. Abiotic factors- nonliving things in an environment such as water, light, soil and temperature Biotic factors- living things The Water Cycle Transpiration water evaporates from plants Condensation Condensation Precipitation Accumulation Respiration liquid water becomes water vapor (gas) Water turns from gas (vapor) to liquid Water falls from the sky Runoff Evaporation Animals release water vapor * * *
