Soil
(i) De composer bacteria help in decomposing matter in the soil. (ii) It helps to maintain fertility in soil. (iii) Bacteria like cyanobacteria help in nitrogen fixation.
Removing the forest vegetation increases soil erosion. That soil is washed out into waterways when it rains, increasing the particulate matter in waterways.
how plentiful are bacteria in water and soil
Soil bacteria are the natural soil microorganisms that break down soil components into plant food.
By keeping waterways open?
Yes bacteria changes an environment.
Some components of the physical environment include: 1. Water 2. Natural Vegetation 3. Landforms/Rocks 4. Weather and Climate

When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use. Other types of bacteria are able to change nitrogen dissolved in waterways into a form that allows it to return to the atmosphere.
