Answer:
<em>Ecological succession</em>
Explanation:
Ecological succession can be described as a series of processes by which a climax community arises gradually in an area where there was no form of life before or the previous ecosystem was destroyed bu disasters such as fire, flood etc.
Ecological succession is of two types:
Primary succession occurs on lands where there was no form of life before. On the other hand, secondary succession occurs in lands where there was an ecosystem before which was destroyed.
Answer:
controlled experiments ( third choice)
Answer:
The scientific method is a process for experimentation that is used to explore observations and answer questions. Does this mean all scientists follow exactly this process? No. Some areas of science can be more easily tested than others. For example, scientists studying how stars change as they age or how dinosaurs digested their food cannot fast-forward a star's life by a million years or run medical exams on feeding dinosaurs to test their hypotheses. When direct experimentation is not possible, scientists modify the scientific method. In fact, there are probably as many versions of the scientific method as there are scientists! But even when modified, the goal remains the same: to discover cause and effect relationships by asking questions, carefully gathering and examining the evidence, and seeing if all the available information can be combined into a logical answer.
