1. Free nitrogen in the air. 2. Bacteria fixing nitrogen. 8 Decomposers breaking down waste. 9. Bacteria releases nitrogen.
Most organisms cannot use free nitroben. Nitrogen fixation by bacteria provides a compound that organisms can use.
TRF= many species, constant temperature, a lot of precipitation. Desert,= few species, extreme temps, and very little precip.
nitrogen cycle
First more erosion will occur. Slowly secondary succession will occur and young saplings will emerge, then eventually trees
In the grassland, large grazing animals keep young trees from growing. The tundra lacks rainfall is is too cold for trees.
When a species moves into a new area, it must compete for resources. If the new species cannot find its niche, it will die.
Suppose loggers cleared a large area of boreal forest. Describe the natural changes that would occur in the area over time. Use some science vocabulary.
