Detailed explanation-1: -Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.
Detailed explanation-2: -What is the link between fossil fuels and climate change? When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 1C.
Detailed explanation-3: -Answer and Explanation: Carbon as carbon dioxide, an abiotic factor, enters the biotic realm of an ecosystem through photosynthesis by either plants or photosynthetic microorganisms.
