Organisms in their Environment

can be carried out by green plants and algae

chlorophyll--> absorbs the suns light energy

PHOTOSYNTHESIS-

carbon dioxide + water ---> glucose + oxygen

process for photosynthesis- 

1) carbon dioxide is taken into the leaves + water taken up into the roots

2) chlorophyll traps the light energy

3) energy is used to convert the carbon dioxide and water into glucose (sugars)

LIGHT- lack of this would slow down the rate of photosynthesis as light provides energy for this process.

TEMPERATURE-  if its cold, the enzymes do not work as efficiently and will slow down the rate of photosynthesis

CARBON DIOXIDE LEVELS- if these levels are too low, there will be less photosynthesis

the glucose produced by photosynthesis may be:

• converted into insoluble starch for storage
• converted into fats and oils
• used to produce cellulose
• used to produce proteins

mineral elements-

• nitrogen-- nitrates-- protein/ amino acid
• magnesium-- magnesium ions---making chlorophyll

physical factors that may affect the distribution of organisms-

• temperature
• availability of nutrients
• amount of light
• availablility of water
• availability of oxygen
• availability of carbon dioxide
