It was used to understand something that cannot easily be seen. It was used to prove that smoking causes health problems. It was used to demonstrate a pattern. It was used to represent something big.
Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy
D, this competition effects death rates, birth rates hence effecting growth rates, in A less dense area competition would be low increasing birth rates and growth rates while decreasing death
