Question

In all organisms some of the energy that is taken in is____.

Answer 1

Lost to the environment in the form of heat.

Answer 2

Answer:  A) Lost to the environment in the form of heat

The chemical energy is the form of energy that is obtained from the food being eaten by the organism. This energy is converted into different forms.These include kinetic energy (required during muscular movement or contraction), electrical energy (required to transmit the nerve impulse) and light energy (useful in producing bio luminescence by the organisms). All these activities occurred due to different forms of energy, results in various exothermic reactions occurring inside the body of the organism. The product of exothermic reaction is heat energy, which is released as a by-product. This energy cannot be recycled to produce any other form of energy, that can be used again by the organisms. This energy is lost from the ecosystem.
