Plants increase the viability of life on Earth. They are the bases of every food chain. They give their energy to consumers and herbivores. They produce oxygen for other living creatures. They even produce food and shelter for many of us.
<span>Plants breathe in carbon dioxide and breathe out oxygen. Animals breathe in oxygen and breathe out carbon dioxide. So they support each other. </span><span>Plants are at the start of every food chain. </span>
The length of LM is twice as the length of QR and the length of MN is twice as the length of RS. By Pythagorean theorem, the length of LN is twice as the length of QS. Then, .
The temperature begins to increase with altitude in the stratosphere. This warming is caused by a form of oxygen called ozone (O3) absorbing ultraviolet radiation from the sun.The overlying mesosphere does not absorb solar radiation, so the temperature decreases with altitude.
