ecology
food chain
producers
-make their own food
-contain chlorophyll to absorb light to convert carbon dioxide and water into glucose
-
-begins with producers
-generally no more than 4 levels
-food chains are linked together to form a food web
energy transfer
-sunlight is main energy source
-energy flows from sun to first trophic level
-chlorophyll in producers absorb light and transfer it to chemical stores of energy in food
-only 10% of energy in the chemical store of food is passed from one trophic level to another
-90% of energy is transferred to the energy store of the environment directly or undirectly as heat
carbon sinks
-area that stores carbon from the atmosphere for a long period of time
-stores more carbon than it releases
forests
-large amount of carbon compounds are produced and stored in trees when they absorb carbon dioxide during photosynthesis
-
-
global warming
-
greenhouse effect
-carbon dioxide forms a layer over earths surface and traps heat within the atmosphere
-causes global warming
-
carbon cycle
-carbon in nutrients is recycled in ecosystems
-ensures a continuous supply of carbon dioxide for plants to carry out photosynthesis to make carbon compounds which is a store of chemical energy
-allow energy to flow through the ecosystem as chemical stores of energy in carbon compounds
-regulate amount of carbon dioxide in the air
