Why is the sun the ultimate source of energy for food chains and food webs?

Explanation: The sun is the ultimate source of energy for all things, as without the sun, producers could not make their own food, as no photosynthesis would happen. Other animals depend on producers as their food sources, and so if no photosynthesis happens, all producers die out, and other animals will also die.

What is the main source of energy in the food web?

the sun
The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Why is the sun the source of all energy in a food web?
