What is the energy amount of all living things?

Answer 1

Energy cycle

A fascinating parallel between plant and animal life is in the use of tiny energy factories within the cells to handle the energy transformation processes necessary for life. In plants, these energy factories are called chloroplasts. They collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria. These produce a versatile energy currency in the form of adenosine triphosphate (ATP). This high-energy molecule stores the energy we need to do just about everything we do.

Answer 2

The energy in living things is difficult to quantify as it varies based on the organism and its metabolic processes. However, all living things ultimately derive their energy from the sun through photosynthesis or by consuming other organisms. This energy is then used for growth, reproduction, and maintenance of life processes.
