biogeochemical cycles

Question 1

what is biogeochemical cycles

Answer 1

set of reaction where an element passes from one environment to another in a infinite recycling loop.

Question 2

what are the cycles

Answer 2

carbon cycle
phosphorus cycle
Nitrogen cycle

Question 3

what are the main steps of the carbon cycle

Answer 3

1. photosynthesis: plants capture CO2
2. dead organisms and waste products: decomposes releasing CO2 and CH4
3. Fossil fuels: buried under sediment for years.
4. animal respiration: Carbon ingested returns to atmosphere as CO2
5. Ocean uptake: CO2 dissolves in water
6. Factory emissions: man made sources -not part of natural cycle.

Question 4

photosynthesis reaction

Answer 4

6CO2(g)+6H2O(l)+solar energy—–C6H12O6(s)+6O2(g)

Question 5

cellular respiration reaction

Answer 5

C6H12O6(s)+6O2(g)—6CO2(s)+6H2O(l)+energy
