Describe how energy and homeostasis are related in living organisms.

Explanation:

Energy and homeostasis are related in living organisms because we need energy in order for our systems to stay balanced and work to keep our bodies in

All organisms must intake sufficient energy on a sufficiently regular basis to fulfill the minimal requirements of homeostasis and allowing for input energy gaps to be covered by natural energy storage mechanisms, which storage can be filled during sufficiently regular periods of excess input energy.

Cells are homeostatic; viruses are not

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
