Explanation:
those are the abiotic factors
<span>The absence of the predator in the experimental plots led to a rise in population of the two species hence suppressing the other species since they were the prey of the Sea stars. But when the sea stars were present, they maintained a balance in the species diversity by feeding on Mussel and Barnacle species.</span>
The explanation regarding the advantage of reproduction that represents the graph should be described below.
Advantages of reproduction:
Here the graph represents the bacteria population that should be raised as the time passes. At the time of 1st hour, the bacteria population should be 50 per ml.
In the second hour, the population should be doubled. In the third hour it should be 200 per ml and in 3 and half hours, the population should be 300 per ml. So here we can see that the population should be doubled with every hour.
