1. 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

2. 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

3. 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
