1. the producer in this web is plants. GOOD.

2.First -order consumer in this web is organic matter, nematodes, fungi and bacteria.

ORGANIC MATTER IS NOT A FIRST ORDER CONSUMER. IT IS JUST DEAD MATTER. THE ARROW POINTING TO IT IS REALLY NOT CORRECT IN MY OPINION. THE BACTERIA IN THIS WEB ARE NOT FIRST ORDER CONSUMERS. FIRST ORDER CONSUMERS EAT PLANTS. SOME BACTERIA ARE PRODUCERS, THE OTHERS ARE DECOMPOSERS.


3.The high-order consumer is Animals, Birds and nematodes.


4.Decomposers are Fungi and Bacteria.


5.They Decompose.....and give energy to Decomposers...

6.The Animals and the nematodes

7.The Animals and The Birds

GOOD
