A. land plants, tiny water plants
a. slug, frog, newt
b. plants, slug-insect-water fleas, frog-fish-newt, perch-fox, heron
c. water fleas, diving beetles
d. heron, perch
e. one thing that could happen if all frogs suddenly died is that there would be an overpopulation of slugs, insects, and beetles. another thing that could happen would be that foxes would only rely on getting slugs for food so the slugs would soon go extinct and the plants would possibly over populate.
hope this helps!!

Antibiotics can have side effects.
When children take antibiotics at the first sign of an ear infection, they are more likely to have vomiting, diarrhea, and allergic reactions because of the medicine. Also, antibiotics can kill “friendly” germs in the body and cause other problems like diarrhea.
Over-use of antibiotics is a problem.
Antibiotics can help drug-resistant bacteria grow. These bacteria are harder to kill. They can cause illnesses that are harder to cure and more costly to treat. This increases the risk of complications and side effects. The resistant bacteria can also infect other people.
Hope this helps
