Choose the best response that describes that describes a pyramid pattern if 90% of energy lost from level to next but 10% of the energy from the lower level is passed to the higher level.

• Energy is generated at each level

• A small amount of the energy at the trophic level is passed to the next level

• Most of the energy at the trophic level passes to the next level

• An equal amount of energy is available at each other

Energy used for body processes are given off as heat and is not passed to other organisms in a usable form best explains what?

• Some energy at each level is destroyed and cannot be passed to other organisms.

• Less energy is generated by the organisms in higher trophic levels,

• The organisms at each level are less efficient at using energy than those in the previous levels.

• Energy used for body processes are given off as heat and is not passed to other organisms in a usable form.
