NUTRIENT CYCLES Nutrients are chemicals that organisms need to survive. Example – All organisms need Nitrogen to make protein NUTRIENTS must be RECYCLED.

The Chemical Cycles. Unlike energy, matter can be recycled. The Water, Carbon, and Nitrogen Cycles are the three main ways matter is recycled in the environment.

Humans and the Carbon Cycle – Respiration releases __________ into the air. – Burning fossil fuels releases CO 2 into the atmosphere. – Burning of wood.

VIII. Cycles in the Environment

A. Carbon Cycle 1. Originally thought that the Earth was 95% carbon dioxide a. Plants and bacteria removed it and replaced with oxygen b. Today about .04%

2. Living things are the most important 2. Living things are the most important to the carbon cycle (made of carbon) a. Photosynthesis 1. H2O+ CO2+light C6H12O6+ O2 b. Respiration 1. C6H12O6 + O2  H2O + CO2 + energy

3. Most carbon is tied up in living organisms a. Also in oceans b/c its easily dissolved b. Rocks also have a lot c. Some as coal, oil, and natural gas 4. Other sources of atmospheric carbon is through burning of fossil fuels and volcanic eruptions

B. Nitrogen cycle 1. Everything needs N in order to make amino acids so they can make proteins 2. Most things cannot use gaseous N 3. Only specific types of bacteria are capable of “fixing” it into useful forms 4. Several steps are involved in the process

a. N-fixing bacteria converts N into NH3 (ammonia) 1. Legumes have colonies of these bacteria in nodules on roots b. Other bacteria make nitrite and nitrate out of ammonia c. Nitrate is used by plants to make protein

d. Animals get nitrogen by eating plants e. Animals and plants die and are consumed by decomposers 1. Ammonia is a by product of decomposition f. Can remain in the soil or go back into the air to start the process over
