Question

The original source of energy in food chains comes from

Answer 1

Answer:

Nearly everything eats sunshine – or eats something else that ate sunshine. The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

This process begins the flow of energy through almost all food webs. Food is sunshine stored in chemical form. Organisms use the stored energy in food to fuel all living processes. Food is organic molecules that serve as fuel and building material for all organisms. The breakdown of food molecules enables cells to store energy and to carry out the many functions of the cell and therefore the entire organism.

Answer 2

Answer:

The energy content of all food molecules can be traced back to the Sun. It is the process of photosynthesis that locks the Sun’s energy into simple carbohydrates like glucose.
