Presentation transcript:

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! (Carbon SINK) Cyanobacteria
