Question

Grass obtains 10% of the energy of the Sun. When a mouse eats the grass, it gets only _____ of the Sun's energy while _____ is lost as heat.

Answer 1

Grass only obtains 10% of the energy of the Sun. When a mouse eats the grass, it only gets 1% of the energy of the sun, while the remaining 9% is lost as heat. Remember, an average of 10% of the sun’s energy is transferred, in each link of the food chain. So, the answer would be 1% of the sun energy.
