Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of lev
vovikov84 [41]

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.

If you are driving down the road, how do you know that the car is moving (think about your reference point)?
NISA [10]
If your car is changing speed by accelerating or decelerating, or changing directions by turning or hitting a bump, your body can sense these accelerations. You might be pressed against the back of your seat while speeding up or against the car door as you turn for example. If you are cruising at a constant speed, with no changes in speed or direction, you wouldn't be able to feel it. You would need to use your other senses. You could see the scenery going by through the windows, with closer objects moving by more quickly than objects in the distance. You could also hear sounds like the wind rushing by and the hum of the tires rolling on the highway.
