The fertilizers used by farmers can have negative effects on aquatic ecosystems because there is every possibility that the runoffs from the fields can create an algal bloom in the nearby water body. This algal bloom can have a very negative effect on the living organisms of the aquatic body. I hope it helps.
The flooding of half part of the forest have successful separate the population of frogs in that ecosystem into two different set of frogs. This is an example of allopatric speciation, that is, the population become separated as a result of geographical barrier. This separation will make the two set of frog population to become new species. On the long run, the two species may become unable to relate sexually.

I believe the answer is comparative anatomy. It is the study of the similarities and differences in the structures of different species.

Angiosperms are the largest group of plants on earth. They account for approximately 80% of all known living plants. There are about 270,000 known species of angiosperms that live on the earth today.
