Here the producers are the pondweed and the microscopic algae
Mayfly nymphs eat the pondweed and microscopic algae, and freshwater shrimp eat the microscopic algae
Dragonfly nymphs and brown trout eat the mayfly nymphs and freshwater shrimp
Brown trout also eat the dragonfly nymph!
Efficiency = (4KJ ÷ 100KJ) × 100 = 4%
To make new cells
No warm blooded animals loose more as their body has to be kept at a constant temperature
Some of it is inedible or can’t be digested e.g. bones and teeth, fibre and cell walls
So much energy is lost at each stage that there is not enough left to support the organisms after 4 or 5 stages
It is recycled in the soil and eventually new plants will use it
Less material and less energy is wasted this means more food can be produced
More food would be made as less energy is lost, so in the limited land space enough food would be made to go around
