|
What is the main energy source for the Biosphere? |
The Sun |
|
Primary Source of Increased Atmospheric Carbon Dioxide |
From when humans extract and burn fossil fuels |
|
Process of Nitrogen Fixation |
Once atmospheric nitrogen has been fixed into nitrates, it is assimilated by green plants, some of which are eaten by animals and released as waste. Some goes to gas and then is released into the atmosphere |
|
Pros/Cons of Biofuel |
Pros: Offer new markets for farming industry Cons: Takes more energy to produce than it provides Effects of land use change and energy are not taken into account |
|
Reason Coconut palm trees are widely dispersed |
Coconuts can float in the oceans for months or years without losing their fertility. They then wash up on beaches and colonize |
|
Short Term Effects of Wildfires |
The composition of the biota is changed, and if the fires occur more frequently, the change may be more than temporary |
