Answer :
Final answer:
Organisms use different sources of energy for metabolic activities, including sunlight and consumed food.
Explanation:
All organisms use a source of energy for their metabolic activities. Some organisms capture energy from the sun and convert it into chemical energy in food. Others use chemical energy in molecules they take in as food.
Plants use energy from sunlight to make sugar and other organic molecules. Both plants and animals use cellular respiration to derive energy from the organic molecules originally produced by plants.
Animals receive their energy by consuming plants or other animals. They must eat plants or other animals to get carbohydrates, fats, and proteins and the chemical energy stored in them.
