All organisms need energy to live. reason:2 when temperature is very high than organism cannot survive due to not geeting its daily food or basic requiements such as water of its body. Why organisms need energy. The series of steps where glucose is broken down to release energy begins with a metabolic pathway called glycolysis. Sexual reproduction produces offspring that are genetically unique and increases genetic variation within a species. If the supply of energy is interrupted, that system is no longer an organism, it is now an aggregate of lifeless chemicals. All organisms that perform aerobic respiration, the process where glucose and other food molecules are broken down for energy, require a regular supply of oxygen. - Lipids can be used to store energy. Why do living organisms need energy and where does this energy come from? Most carbohydrates (sugars and starches) are converted into glucose before they are broken down in the cytosol to release energy. This food undergoes the process of oxidation to produce energy. Without an. Water creates pressure inside the cell that helps it maintain shape. Therefore, living organisms need a continues energy .

Every living organism, animals and plants, need a continual supply of energy to perform the processes necessary for reproduction and survival. This process is done through a reaction called cellular respiration. 4.2.U4 Energy released from carbon compounds by respiration is used in living organisms and converted to heat. This is because the conditions inside our body must be carefully controlled for it to function effectively and survive. All organisms need energy to live. One of the activities that define organisms is that at some point in their life, or throughout it, they grow. Every cell in a living organism requires energy to live. heart outlined. For an organism to be recognized as a living thing, it must take in energy and use it to sustain life. When organisms eat food, the energy in the bonds of the food molecules becomes available to the organism for use in life processes.
