Banning harmful pesticides that kill consumers

Answer 1

I would say banning harmful pesticides that kill consumers, Since coal and oil are not part of any cycle, they would probably lie under the earth until the end of our solar system, you can rule out answer b and c. fish and 'plant consumers' are both part of a cycle. In this case fish are mostly top of a consumers cycle and are therefore less crucial to a certain cycle. Decomposers are usually not that specific in in what they break down (In this case, they don't care if they break down fish or prawns or seaweed or whatever) so you can say fish aren't that crucial to a food chain. Using harmful pesticides will kill bugs, including bee's which are of course crucial to pollination. And these pesticides can then accumulate in birds eating the poisoned bugs. Birds are responsible for spreading all kinds of seeds etc. This would influence the composition of the ground at etc etc etc. So I'm not completely sure, but that's what I would answer
