Question

the image below shows the percentage of energy that is available to each trophic level in an energy pyramid. which of the following best describes the flow of energy from producers to consumers in an energy pyramid? chemical energy is converted to heat energy, which is transformed into radiant energy at the top of the pyramid. heat energy flows through each level of the pyramid, until it is lost to the environment as chemical energy. radiant energy is converted to chemical energy, some of which is lost to the environment as heat. radiant energy flows through each level of the pyramid, until it is transformed to chemical energy at the top of the pyramid.

Explanation:

In an energy pyramid, producers capture radiant energy (from sunlight). Through photosynthesis, they convert it to chemical energy. As energy is transferred from one trophic level to the next, some energy is lost as heat at each level. Heat energy is dissipated into the environment at each step of the energy - transfer process in the pyramid.

Answer:

Heat energy flows through each level of the pyramid, until it is lost to the environment as heat.
