Aerobic respiration occurs were cell use oxygen to convert glucose into energy. When you breath in,you breath in oxygen,when you breath out,you breath out carbon dioxide.

During cellular respiration,our body needs the oxygen we breath in,to get energy from the food we eat. cell uses oxygen to break down sugar.

Answer:

  • The cellular respiration occurs in two main forms or mechanisms, the first one is the aerobic respiration which obviously takes place in the presence of the oxygen,O₂ molecule. While, the second takes place in the absence of the oxygen,O₂ molecules.
  • For, the aerobic form of cellular respiration the oxygen is required to be present during the  process of  releasing the optimum amount of energy or executing of the whole process in a more proper way.
  • <u>As, the aerobic respiration is executed in the following three steps:</u>
  1. Glycolysis.
  2. The Kreb's cycle.
  3. And the electron transport chain, to which the oxygen is mandatory or required.

Describe the three types of predation and give an example of each.
uranmaximum [27]
<span>True predation is when a predator kills and eats its prey. Some predators of this type, such as jaguars, kill large prey. They tear it apart and chew it before eating it. Others, like bottlenose dolphins or snakes, may eat their prey whole. In some cases, the prey dies in the mouth or the digestive system of the predator. Baleen whales, for example, eat millions of plankton at once. The prey is digested afterward. True predators may hunt actively for prey, or they may sit and wait for prey to get within striking distance. In grazing , the predator eats part of the prey but does not usually kill it. You may have seen cows grazing on grass. The grass they eat grows back, so there is no real effect on the population. In the ocean, kelp (a type of seaweed) can regrow after being eaten by fish.</span>
