run out and organisms would die. The amount of carbon nitrogen and oxygen on the earth is fixed‚ they can exists in different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each other‚ and you couldn’t have one without the other. Carbon is an essential component of all organic substances‚ necessary in nucleic acids‚ proteins‚ carbohydrates. The only way that can enter ecosystems is when it’s used

Seven characteristics of life In life‚ there are seven different characteristics these being; movement‚ excretion‚ respiration‚ reproduction‚ irritability‚ nutrition and growth. Below‚ I will explain each of the characteristics in detail. Reproduction means; “the production of offspring by a sexual or asexual process” (oxford concise colour medical dictionary‚ 2007). Animals and plants do this in different ways‚ animals need two parents‚ and therefore the offspring will share both of the parent’s

about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration‚ the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration‚ the production of lactate during which the muscles have a limited supply of oxygen‚ and however keep working despite this. Aerobic respiration requires oxygen
