Depletion of ozone leads to ecosystem health risks www.nasa.gov
Carbon Cycle Temperate rainforests store vast amounts of carbon, both above and below ground.
Carbon Cycle Brazil’s rainforests re-cycle carbon faster than any other ecosystem.
Carbon Cycle Today, the earth’s atmosphere is accumulating CO 2 faster that it can be sequestered. vrs Carbon sink Carbon stink
Carbon Sinks: 1. Marine viruses and phytoplankton 2. Forests 3. Coral reefs
Carbon Cycle The earth’s “core” temperature is rising

Ecosystem Ecology Chapter 54. Ecosystem ecology emphasizes energy flow and chemical cycling. An ecosystem consists of all of the organisms in a community.

Causes of the Greenhouse Effect 1 Energy from the Sun beats down on the Earth. 2 Some energy is reflected into space, the rest enters the atmosphere.
Biogeochemical Cycles A biogeochemical cycle is how animals obtain useful inorganic and organic materials, use them, and return them to be recycled.
