A species of reptile lives on several different islands some of the islands contain a certain species of mammal while some do not on the islands without the mammal the reptile species have a carrying capacity of 240 individuals per square kilometer on islands with the mammal the reptile species has a carrying capacity of 150 individuals per square kilometer by what percent is the carrying capacity for the reptile species reduced by the presence of the mammal species

23%

Explanation:

The maximum number of individuals of a population that a particular ecosystem can hold is known as the carrying capacity of that particular population.

As the reptiles living in the ecosystems, without the mammal species, had to compete less, hence there carrying capacity was more in such areas.

There s a difference of 23% in the carrying capacity fir reptiles in the areas where the particular species of mammals were present.

240+ 150= 390

240-150= 90

90 divided by 390 and then multiplied by 100 gives 23%.
