Answer:

A.

1.) Base on the first picture, we can see a fisher man in there who uses net to catch the fishes. For me the interaction between or among organisms is either beneficial or harmful because the situation depends of what kind of fisher man he is. If he is a bad or an irresponsible fisherman then he will not bring the small fishes that possibly got caught by the net back on the swamp. Otherwise, if he is a good and a responsible fisherman then he will bring the small fishes that possibly got caught by the net he uses back to the swamp. It may bring benefit or will harm the fishes in the swamp.

2.) The interaction between or among the organisms in the second picture is beneficial. As we can see, their are ducks in their and maybe it is their habitat. For me it is okay for them to live on a swamp that they are comfortable with for them to live freely and away from those irresponsible people who will just bring them harm.

B.

1.) The interaction between or among the organisms in the first picture is harmful because there are garbages we can see on there. These garbages will give a bad effect or big damaged to our mangrove ecosystems especially to the organisms living in there like fishes. It can also damage our coral reefs.

2.) The interaction between or among the organisms in the second picture is harmful. As we can see there are a lot of living organisms on there living together. For me it is harmful because they don't belong to each other and they maybe just hurt each other. There are specific habitats for each of them.

I hope this one can help! Please correct me if I'm wrong and don't hesitate to ask me about my answer if there was a part that is not clear for you..Thanks!!
