Answer:
The percentage of food consumed provides an idea regarding the accessibility of food for the organism. In case, if the percentage of food consumed is high it demonstrates that there is no competition amongst the species for the food, and it shows the success rate of that particular species.
On the other hand, when the percentage of food consumed becomes low in a specific region, it demonstrates that there is a competition for food and resources between the species, and thus, one can witness a decline in the number of the species that gets out-compete. Thus, it can be said that the number of specific species is directly equivalent to the percentage of food present.
