Document Summary
There have been 5 mass extinctions (wiping out a certain species off the planet) and a. Environmental consequences: result of, unintended consequences, acid rain, ozone depletion, climate change, ozone is getting thinner because of the gases we create, acid rain caused by the burning of fossil fuels, conscious manipulation, deforestation, hydro dams, agriculture.

Conversion of solar energy through living organisms: hierarchical trophic levels, each level is called a trophic level.
