Biogeochemical Cycles

Water Cycle Complete the video and then answer the questions provided below. Use the terms given below to label the followingwater cycle. Precipitation Evaporation Condensation Run off Transpiration Precipitation Run off Evaporation Condensation Transpiration Match the parts of the water cycle with their correct definition Condensation Water in the atmosphere forms clouds Evaporation When the water moves from a liquid form to a gas form (From lakes and oceans into the atmosphere) Transpiration Special term used for when water evaporates from plants Run Off Water that is not absorbed by the ground Precipitation When water falls to the ground in the form of rain, snow, sleet, etc Carbon Cycle Complete the following video and then answer the questions below. Classify the following factors involved in the carbon cycle as - biotic (living) vs abioitic (non-living). Biotic Plants Animals Decomposers Abiotic Sun, Soil Water Atmospheric Temperature Carbondioxide and Oxygen gas Fossil fuels (coal oil) Use the terms given below to label the following carboncycle. Photosynthesis Respiration Combustion Decomposition Photosynthesis Respiration Decomposition Combustion Nitrogen Cycle Complete this video and then answer the questions below. Identify the role of the following organisms in the Nitrogen Cycle. Organisms Role Nitrogen fixing bacteria Bacteria that converts atmospheric nitrogen (unusable form) into ammonia (usable form) Nitrifying bacteria Bacteria that converts ammonia into nitrates that can serve as nutrients for plants. Denitrifying bacteria Bacteria that converts unused nitrates back to atmospheric nitrogen (unusable form) Plants Absorb nitrates through roots and use it to synthesis proteins. Animals Consume plants (producers) to obtain proteins. Decomposers Break down dead organisms and nitrogenous waste, releasing ammonia into the abiotic environment.
