photosynthesis- converts solar energy to chemical energy by absorbing sunlight
-Inputs- 6H20---->6C02 (light energy)
-Outputs---> CH12O6 (glucose) 602
-Light reaction inputs: H20, ATP, NADPH
-Light reaction outputs: 02, ATP, NADPH
-Chemical formula : 6CO2 + 6H20---->C6H1206+602
-Chloroplast : chlorophyll containing organelles found in the cells of green plants, they capture light energy and convert it to light energy
-Light Dependent Cycle: light energy is converted to chemical energy in the form of ATP, resulting in the splitting of water and the release of oxygen.
-Calvin Cycle: simple sugars are formed from carbon dioxide using ATP and hydrogen from the light dependent reactions (stages)
-How is light transformed into chemical energy? The light is captured by the chlorophyll in chloroplasts of plant cells.

Laws

tanyalozano001 — 2016-12-14 03:49:13 UTC

1)Law of Conservation of matter - Matter is neither created or destroyed
2)Law of Conservation of energy - Energy is neither created or destroyed
3) Law of Conservation of mass - mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. (the mass of the products in a chemical reaction must equal the mass of the reactants)
4) How is energy equal to matter? Energy can be transformed into massive particles, and mass can be transformed into energy

Carbon Cycle

tanyalozano001 — 2016-12-14 03:57:58 UTC

- cellular respiration is the process where mitochondria breaks down food molecules to produce ATP (the three stages include: glycolysis, the citric acid cycle, and the electron transport chain)

Food Web Energy Pyramid

tanyalozano001 — 2016-12-14 04:38:25 UTC

- only 90% of energy available is lost during the transition, 10% is passed onto the next

Bottom- 100%
2nd - 10%
3rd- 1%
Top- 1%

Bottom:
-autographs
-producers
-produce own food <- plants
-sun gives energy

2nd level:
-herbavors
-heterotrophs

3rd level:
- secondary consumers
-carnivors/ omnivoirs
-fish, human, squirrels, snakes

Top:
- tiertiary consumer

Decomposers- break down matter from dead organisms (include: worms, bacteria, fungi
