Does energy recycle in a foodchain?

Answer 1

As a general rule of thumb, a secondary consumer can only utilize 10% of the energy that the primary consumer yields. As you progress through the tiers, 100% becomes 10% and 10% becomes 1% until the energy distribution is so small that it is no longer relevant.

Answer 2

Energy diminishes at each step in the food chain, if you think of it like a pyramid, you would have :

1 fox

30 rabbits

500 lettuces

Energy is lost at each step, the rabbits need to eat a lot of lettuces to get the energy they need just to live, to respire, move etc. The fox then uses a lot of energy doing the same things, and needs to eat several rabbits just to get this energy. Take into account that eating something does not give all of its energy to you, as energy is lost in digestion, and you can see that at each level there is less energy present than before, for example:

500KJ

5000KJ

50000KJ

In the same pyramid as before.

Answer 3

As energy is moved across a food chain, as in one thing eating something else, the amount of energy decreases somewhere around 90% per transfer.

Answer 4

No. Energy is the one thing, above all others, that isn't maintained in different cyclical processes.
