1. Microorganisms (Bacteria) In Ecosystems
Write a summary of how microoganisms contibute to each of these aspects of the ecosystem!
Converting Nitrogen:
Nitrogen fixation (nitrogen-fixing bacteria)
Making nitrates: Nitrification (nitrifying bacteria)
Denitrification (making gas-denitrifying bacteria)
Decomposition
Decomposition:
Decomposers recycle matter so other living things can use it in the future! 
Energy doesn’t get recycled; it goes in one direction-away from the sun
Microorganisms
(Bacteria)
In Ecosystems
Disease:
Some bacteria are parasites and cause disease!
This can weaken populations.
Sometimes, beneficial bacteria can help by competing for resources with “bad,” or pathogenic bacteria.
Photosynthesis:
Some bacteria can capture solar energy and convert it into chemical energy!
