Greenhouse gases(also known as GHGs) are gases in the earth's atmosphere that trap heat, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals.
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases.
The original source of phosphorus in a terrestrial ecosystem is soil microorganisms. soil becomes deficient in phosphorous leading to ecosystem retrogression. phosphorous can be found in our body, it builds strong bones and teeth. hope it helps!
