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.
Answer : The percentage of food gives an idea about the food availability for the species of organisms. If the food percentage is high the species is observed to be more successful; on the other hand if the percentage is low the species is found to shrink in numbers. The numbers of particular species is directly proportional to the percentage of food. Also, it shows the options of other food resources on the basis of their availability.
