When the only force acting<span> on a falling </span>object<span> is </span>gravity<span>, the </span>object<span> is said to be in free fall. </span>force<span> of </span>gravity<span> is an unbalanced </span>force<span>, which causes an </span>object<span> to accelerate. Near the surface of Earth, the acceleration due to </span>gravity<span> is 9.8 m/s2.</span>

The scientific method is a process of steps in order to get a conclusion. First, a scientist will observe something. It could be really anything. Then he/she will ask themselves a question. Like how does it do that? Or why does it do that?
Then they will form a hypothesis. This is where you will ask yourself what will be the outcome of the experiment.
Next you actually perform the experiment. If the experiment comes out as your hypothesis predicted, then you accept your hypothesis.
If not, you reject your hypothesis.
Of course, in science you just don't do one experiment. You do it multiple times and even with different circumstances.
True, when succession occurs after a disaster, like a wild fire, its called secondary succession.
Secondary succession occurs when an existing population has been reduced due to a fire. So that it occurs on soil that was already present prior to the disaster.
When animals are fighting over resources the number of one animal might decrease because the other animal would've tried to kill it and stay alive
when there is competition the population size of one animal might decrease while another increases<span />
