Answer:
Cumulus stage
Explanation:
Most electrical storms form from stages, their first stage is cumulus:
In this stage, the sun warms the surface of the earth, this makes the heat from the surface warm the nearby air, as the hot air is lighter than the cool it begins to rise. If the air is humid, then the hot air condenses into a culumus cloud. The cloud will continue to grow as long as the hot air continues to rise.
I think the first option is the answer.
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.
