All systems require energyinput
this is sunlight
Also need to input matter

destroyed
but can changeform
All outputs are examples
of

If detritus lands in field it is an input
in streams then it is an output

As you gothrough food chain you loose biomass form of

upfoodchain biomass gets lower
lose energy as you go up
