Suggest what happens to the populations of birds that feed on fish.
Answers
Answer:
It depends upon the environment from where the fish is taken. If the place of fish is close to humans or known to them,they will obviously ruin the environment by throwing trash in it or using it for farming purposes.if they grow underwater crops they will surely protect them by any means.they will sprinkle insecticide or pesticides which prevents growth of unwanted plants or weed.
The pesticides and insecticide have some chemicals in them,which gets eaten up by phytoplankton (tiny aquatic organisms).These phytoplankton gets eaten up by zooplankton (small aquatic organisms).These gets eaten up by small fishes so the percentage of chemicals in the body of fishes increases rapidly and the birds eat these fishes also intake some percentage of chemicals with them.
Thus the chemical substances are harmful and causes major damage to the body of the bird and fishes . At last they die miserably for no reason.
Explanation:
The population of birds decreases ultimately because of humans interfering in their habitat.
Humans are serious killer. They should be alert to what their actions can cause.
That's it. Done
