All living organisms must have the ability to reproduce. Living organisms need energy for their daily activities, and for them to be alive. Then the sun goes down, it's dark, and you die. Outline the reason why respiration releases heat. During cellular respiration oxygen is used to convert the chemical energy in sugar to a form that the organism can use. This energy is released during cellular respiration in the form of ATP. and is used: Plants don't need much energy, but they do need energy, if only to stop viruses and microbes from digesting them where they stand. Living things obtain and use energy. Why Do Living things need Energy? All organisms need energy to live. This energy is used: to drive the chemical reactions needed to keep organisms alive - the reactions to build complex carbohydrates , proteins and lipids from the products of photosynthesis in plants, and the products of digestion in animals, require energy. The amount of sunlight in an area determines what living thing can survive there. Why do living things need glucose if ATP is the molecule that cells use for energy? Answer (1 of 5): The definition of an organism is one of a dynamic system: energy in, energy out. Why don't autotrophs just make ATP and be done with it? Why organisms need energy. In order to carry out various life processes like respiration, circulation, excretion etc., living organisms need energy. Autotrophs plants capture the sun's energy and use it to make food. The food you eat and the air you breathe are made of matter. 4.6. There are many organisms that live in place where light does not reach, such as the depths of oceans or underground caves. During cellular respiration oxygen is used to convert the chemical energy in sugar to a form that the organism can use. For an organism to be recognized as a living thing, it must take in energy and use it to sustain life. Do All Organisms Show Growth?
