<span>Organisms
that expend energy to regulate some or all of their internal conditions are
known as regulators. Regulators are organisms that can control their internal
environment regardless of external environmental change. Regulators achieve this
by homeostatic mechanisms and it requires a lot of energy. Examples of
regulators are mammals and birds</span>

<span>The process by which a plant absorbs energy from the sun is, as you know, photosynthesis.
Remember the Law of Conservation of Energy - when energy is transferred,
it is neither created nor destroyed but rather takes a new form.
In this case, the plant takes energy in from the sun (through sunlight,
which transfers through radiation) and "leaves" the plant after the
process has occurred in a form of potential energy - the oxygen produced
in this process has potential energy.</span>
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
