Organisms need energy to carry out various biological processes such as growth, reproduction, movement, and maintaining homeostasis. Energy is required for the synthesis of molecules, repair of tissues, and functioning of cells. It is also essential for carrying out essential metabolic reactions that sustain life.
The number of organisms typically decreases as you move up the food chain. This is due to energy loss at each trophic level, with only about 10% of energy being transferred from one level to the next. Therefore, less energy is available to support a large number of organisms at higher trophic levels.
Archaea can be heterotrophs, autotrophs, or even mixotrophs. Some archaea are known to use organic compounds as a source of energy and carbon, while others can produce their own energy through processes like chemosynthesis or photosynthesis.
The mitochondria need oxygen and nutrients to make energy.
We need energy so that we can walk, talk, sleep and do everyday activities. If we did not have energy we wouldn't be alive. All animals use and absorb energy. Objects don't need energy but things that want to live need energy. We obtain energy for the sun, sugar, nutrients, etc...Additional answerAll living things are really just a bunch of chemicals, and there are a considerable number of chemical reactions that take place. Most chemical reactions need energy to take place.
Plants need energy for photosynthesis, which is the process they use to convert sunlight into chemical energy in the form of glucose. This energy is essential for the plants to grow, develop, and produce food for themselves.
The sun
Photosynthesis.
They can turn energy from the sun into a form used by other organsims.
Cells
yes
i want to know the answer for my queston
chemical weathering living organsims
Hello
i have no idea
Yes, they do.
The study of microorganisms is called microbiology.
