The answer is: A) They provide a source of energy

We currently generate our electricity by putting magnet on spinning turbine (the faster the turbine rotate, the more electricity that we can generate)

By creating dams, we can control the flow of water in the dam by closing or opening the dams' doors. This flow of water is strong enough to rotate the turbine to generate electricity. This is why we can say that dams provide source of energy.

mafiozo [28]

Answer:

I'm not writing your paragraph for you, but I'll give you some help on it.

Explanation:

2 animals that will compete are ants

they are constantly fighting for new territory

What happens, is that when the attackers come, the scouts for the defenders spray something (I forget what) into the air. This alerts the more heavily armed troops nearby. If the defenders win, the attacks are driven back to their colony. If the attackers win, the ants in the defending colony are either overrun and killed, or they run. If the attackers win, they find all the larvae in the nest and either kill them to stop the line together, or in some cases, eat them.

Hope this helps.
