Answer

As the python are generalist species, the food availability may not become a factor that determine the carrying capacity of python by the particular ecosystem.

Work Step by Step

The maximum population size that can be sustained in the given environmental conditions is referred to as the carrying capacity of the ecosystem. Pythons are generalists, so the food availability cannot be considered as a primary factor. A generalist species is the one who is able to survive in the wide range of the environmental conditions. The food availability does not serve as the determining factor in the carrying capacity of pythons (generalist species). The declining population of the opossums and raccoons can be an indication of high predation rate. It also indicates that some food sources are declining. However, after a certain time, the python population may decline as the food sources may become limited. So, the python population will not increase exponentially forever.
