Question

The energy pyramid above shows a possible amount of energy, in kilocalories, available in the organisms at each trophic level in an ecosystem. Accoring to the law of convservation of energy, energy can neither be created nor destroyed. If this is true, why is there less energy in the top of the energy pyramid than there is the bottom of the energy pyramid?

Energy is lost between each trophic level as heat.

Answer 2

Well I know each level of energy loses 10% I think like the rest of the energy is used in fat (I think)
I did this in like 7th I am in 10th now so I did this a good bit ago

Answer 3

We are in the same grade... I can't recall. But thanks for your help, it gave me a bit of insight.

Answer 4

I know the answer lol

Answer 5

I am in grade 11 and both of you are right but remember that as you go up the chain the animals get bigger in size also as a result of the organisms moving, excreeting, and feeding all of which requires enegy the enegy also decreases as u go up.....eg a grass takes 100% energy from the sun it uses 10% to respire and when eaten it passes on 90%. Lets say a rabbit ate the grass and got 90% of the enery the rabbit has to run, respire and keep itself warm and also the size of the rabbit in relation to the grass means it also looses energy and so on and so forth....same also applies if the rabbit is eaten by a Hawk.....u get the idea now :)
