Go to: http://shrt.st/v6z
Then to the Links where there are four sections.
For each section investigate at least 2 sites and provide 3 sentences on their content.
Carbon Cycle - how does carbon cycle in the environment?
•
•
•
•
Carbon cycle - good basic information on how carbon cycles.
The Carbon Cycle - NASA's Earth Observatory site does an amazing job of describing how the carbon cycle works.
What Goes Around Comes Around - a very well-written essay on the carbon cycle.
Fish Excretions Help Fight Climate Change - yup, you heard right - fish feces is good for the climate.
Nitrogen Cycle - how does nitrogen cycle in the environment?
•
•
•
•
Nitrogen cycle - good basic information on how nitrogen cycles.
Of Microbes and Men - a very well-written essay on the nitrogen cycle.
The Nitrogen Cycle - NASA does a great job of explaining the cycle as part of their soil science page.
Nitrogen Cycle Animation - watch the nitrogen cycle in action.
Phosphorus Cycle - how does phosphorus cycle in the environment?
• Phosphorus cycle - good basic information on how phosphorus cycles.
• Phosphorus Cycle - the Environmental Literacy Council provides excellent information.
The Effect of Climate Change on Species - natural cycles can be greatly disrupted when the climate changes:
• Birch Trees To Edge Out Aspens In Warming World - explains why birch will drive out aspens in Northern forests.
• Research Shows How Pollutants Affect Tree Growth - how does increased carbon dioxide affect tree growth?
• Climate Change and Birds - egg laying, migration and many other factors are changing.
Carbon Cycle
1. 3-15% of the Oceans’ calcium carbonate comes from fish.
2. This calcium carbonate comes from “gut rocks,” also known as fish feces
3. Carbon is the fourth most abundant element in the universe
Nitrogen Cycle
1. About 78% of the Earth’s atmosphere is nitrogen
2. Nitrogen availability can affect the rate of key ecosystem processes, including primary production and decomposition
3. The atmosphere is the largest source of nitrogen
Phosphorus Cycle
1. Phosphorus does not exist in the atmosphere
2. When there is excess phosphate, algae can sometimes bloom because of excess nutrients
3. Phosphates move through plants and animals quickly, but the process is incredibly slow through rocks and minerals
The Effect of Climate Change on Species
1. Experts predict that concentrations of carbon dioxide and ozone gasses will double in the next 100 years – at least the
rate we’re going
2. In the future, climate change will greatly impact birds, possibly leading some to extinction.
3. Rising carbon dioxide levels make trees grow faster than they normally would – carbon dioxide acts as a fertilizer
