Biogeochemical Cycles: Oxygen Carbon Sulfur Nitrogen Phosphorous Calcium
Oxygen Cycle Brazil’s forests produce 40% of the earth’s atmospheric oxygen
Oxygen Cycle Image obtained from http://www.accessexcellence.com/AB/GG/photo_Resp.html
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
Nature Is “Re-shuffling” The Deck As The Environment Changes
Science Times - Tuesday, September 28, Extinction by Infectious Disease Because o the introduction of Culex pipiens and Plasmodium gallinacium (bird.
MATTER CYCLING IN ECOSYSTEMS Nutrient Cycles: Global Recycling –Global Cycles recycle nutrients through the earth’s air, land, water, and living organisms.
ECOSYSTEMS AND ENERGY FLOW CH 55 Energy flows through ecosystems while matter cycles through ecosystems.
Chapter 3 Nutrient Cycles.
Biogeochemical Cycles. Objectives: Identify and describe the flow of nutrients in each biogeochemical cycle. Explain the impact that humans have on.
Biogeochemical Cycles. Biogeochemical: Chemical elements and molecules that cycle through the Earth’s systems and provide the building blocks for life.
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.
1 Web Search What are coral reefs? How are they formed? 2 Image Search Find a map that shows the areas of the world where coral reefs can be found.
Biogeochemical Cycles A biogeochemical cycle is how animals obtain useful inorganic and organic materials, use them, and return them to be recycled.
1. Review- By what two processes is water cycled from land to the atmosphere Sequence- Describe one way in which water from Lake Superior may make one.
Air pollution – Local and Global Concerns Many atmospheric pollutants are naturally occurring compounds. What are the key human activities that cause levels.
Cycles of Matter. What is the function of the water cycle? It moves water from Earth's surface to the atmosphere and back. What are the three processes.
