the digestion of food is necessary for us to get energy
solar energy
Food provides organisms with necessary nutrients and energy.
Food is necessary for survival because the food contains glucose, and glucose is the only source of energy for living organisms.
Cells get energy by taking in nutrients from food.
Supplies of food, places and sources we can get food from.
The mitochondria in a cell convert food cells into energy. The cell uses that energy to kickstart necessary reactions.
photosynthesis
Digestion is necessary because for energy from the food to be released and carried into the cells in our body the food must be broken down into soluble molecules for it to diffuse into the cells. Then energy is released during respiration.
In a food chain and food web the energy is getting reused by the next level so the energy is not being created or distorted, just reused.
i think it`s sun light is necessary for it to make food
Nutrition is getting food, respiration is turning the food into energy
