6d. Know how water, carbon, nitrogen cycle between abiotic resources and organic matter in the ecosystem and how oxygen cycles through photosynthesis and respiration. Key Terms Abiotic Factors: ____________ parts of an organism’s environment; temp, moisture, light, and/or soil The Water Cycle Water moves between the _________, atmosphere, and _________. The Water Cycle Water molecules enter the atmosphere as water vapor, a gas, when they evaporate from the ocean or other bodies of water. The process by which water changes from a liquid form to an atmospheric gas is called ________________. Water can also enter the atmosphere by evaporating from the leaves of plants in the process of __________________. The Water Cycle Water vapor condenses into tiny _____________ that form clouds. The water returns to Earth’s surface in the form of precipitation. Water enters streams or seeps into soil where it enters plants through their roots. Nutrient Cycles The Carbon Cycle Carbon is a key ingredient of __________ tissue. Biological processes, such as photosynthesis, respiration, and decomposition, take up and release carbon and oxygen. Geochemical processes, such as erosion and volcanic activity, release ___________ __________ to the atmosphere and oceans. Nutrient Cycles Biogeochemical processes, such as the burial and decomposition of dead organisms and their conversion under pressure into coal and petroleum (fossil fuels), store carbon underground. Human activities, such as mining, cutting and burning forests, and burning fossil fuels, release carbon dioxide into the atmosphere. Nutrient Cycles Nutrient Cycles The Nitrogen Cycle All organisms require nitrogen to make proteins. Although nitrogen gas is the most abundant form of nitrogen on Earth, only certain types of bacteria can use this form directly. Such bacteria live in the soil and on the roots of plants called legumes. They convert nitrogen gas into ammonia in a process known as ________________ _______
