establishes the temperature balance of the sea/surface on Earth. Radiated energy does not‚ however‚ have unhindered access to and from space. The atmosphere surrounding the earth also carries the ability to absorb radiation‚ and since the atmosphere has a lower temperature than the surface‚ it absorbs more energy than it emits back into space. Thus‚ energy absorbed by the surface and re-radiated back into space is captured by the atmosphere and remains there. This is known as the Greenhouse Effect‚ and there

are organisms that have a limited ability to control their body temperature. Their cellular activities generate little heat. Their body temperatures rise and fall with ambient temperature changes. Most organisms are ectotherms.
