Ecosystem Cycles Project Ecosystem Cycles Project Purpose: to understand the parts, functions and the interrelatedness of the nitrogen, carbon and water cycles. Directions: make a concept map that includes all 3 cycles. Make sure the arrows are easy to Follow. Colors and animations are a plus. You can be done as a cut and paste the pictures given or provide or draw your own Purpose: to understand the parts, functions and the interrelatedness of the nitrogen, carbon and water cycles.

Objectives Objectives Describe how the primary carbon cycle processes of photosynthesis, respiration, decomposition, ingestion and combustion transport and transform carbon, water and nitrogen compounds as they move throughout the Earth's Biosphere and Geosphere; Identify the four major carbon reservoirs and explain how carbon can move from one reservoir to another; Describe the effects of negative and positive feedbacks on the carbon cycle system. Describe the effect of solar radiation on the water cycle Describe the impact of the food web on the cycles How do bacteria influence the recycling of nitrogen Know the different forms N can take in the cycle Describe how the primary carbon cycle processes of photosynthesis, respiration, decomposition, ingestion and combustion transport and transform carbon, water and nitrogen compounds as they move throughout the Earth's Biosphere and Geosphere; Identify the four major carbon reservoirs and explain how carbon can move from one reservoir to another; Describe the effects of negative and positive feedbacks on the carbon cycle system.

Biogeochemical Cycle Project Bacteria fixate nitrogen Precipitation Absorbption Diffusion Run off Aquifers Ingestion Food web Photosynthesis Respiration Combustion Decomposition Peptide bond Ammonification Herbivores gain nitrogen from plants Nitrification Assimilation Fixation Denitrification Transpiration perspiration Plants absorb fixated nitrogen to bind with carbon Nitrogen binds with carbon to form peptide bond Excretion Evaporation condensation Plants form proteins to make their tissues Carnivores gain nitrogen from other animals Omnivores gain nitrogen from both plants and other animals Organism croaks Organism’s body is fossilized and converted to fossil fuels Lightning fixes nitrogen
