How are food chains formed?

Answer 1

food chains actually starts at the sun. the sun gives light to plants and they grow. herbivore or omnivoress eat these plants. carnivores or omnivores eat these plant eaters. all of this ends up with humans on top of the food chain. we eat everything and some eat us.

Answer 2

All food chains ultimately start with the sun as an energy source. This is often simply assumed, so can be omitted. Therefore, a plant will be the first organism in a food chain, since plants photosynthesise sunlight to produce food. As a rule of thumb, all food chains will begin with a plant that obtains energy from the sun. There are very few exceptions to this rule, such as some microorganisms which live deep in the oceans where sunlight cannot penetrate can acquire energy from sulphur compounds near geothermal ocean vents.
