The correct answer is option Energy is lost at each trophic level.
In a Ecological pyramid, the energy is transferred from the producer to the consumer level. The ecological pyramid is triangular in structure, this is because the number of organism on each successive trophic level is less than the preceding one or the one below it.
The reason of this shape of ecological pyramid is on subsequent trophic level, the amount of energy transferred is only 10%. The rest of the energy is dissipated in the environment in the form of heat. As only 10% of total energy is transferred to the subsequent level, The amount of energy reaching to tertiary consumer is very less that it cannot meet the energy demand of next level.

Explanation:
Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
