Roles of Plants in the Environment
• Photosynthesis
• Nitrogen fixation
• Producers in food webs
Photosynthesis
• Process by which plants
make energy for
themselves
– Happens in chloroplast
of cell
• Chlorophyll- pigment
found in chloroplast
• Take in carbon dioxide
from the atmosphere
• Release oxygen
Nitrogen Fixation
• Bacteria on roots of plant change nitrogen in
the air into a useable form for other organisms
– Most organisms cannot use atmospheric nitrogen
Producers
• Plants are producers in a food web- they
produce food for the consumers
• Basis of food webs and chains
• All consumers rely on producers
• Producers are the limiting factor to how large
a population of consumers can get
