How do organisms get energy from food?

The flow of energy through living things begins with photosynthesis, which creates glucose. In a process called cellular respiration, organisms' cells break down glucose and make the ATP they need.

How do organisms get the energy they?

How Organisms Get Energy. The chemical energy that organisms need comes from food. Food consists of organic molecules that store energy in their chemical bonds. In terms of obtaining food for energy, there are two types of organisms: autotrophs and heterotrophs.

How do organisms obtain and use the energy they need to live and grow?

Living organisms must take in energy via food, nutrients, or sunlight in order to carry out cellular processes. The transport, synthesis, and breakdown of nutrients and molecules in a cell require the use of energy.
