Question

How did energy is transfer in food chains?

Answer 1

Energy flow in an ecosystem starts at the sun which produces all the energy needed for life. Then comes the producers, the autotrophs. These organisms harness the energy of the sun and convert it into sugars. These organisms obtain 100% of the energy they produce. The primary consumers which eat the autotrophs get the next most energy, but this is only 10% of the original energy that the autotrophs got. Next, the secondary consumers, which eat the primary consumers get nutrients, but this is only 1% of the energy that was originally in the plant. Tertiary consumers, at the top of the food chain eat secondary and primary consumers, and they only get 0.1% of the energy.

Every level of the energy pyramid, those organisms only get 10% of the energy from the previous level.
