Complete Question: 
The carrying capacity of the environment for a species is determined by: 
options: 
(a) the reproductive rate of the organism.
(b) the number of organisms of that species.
(c) the state and national wildlife laws pertaining to that species.
(d) the age distribution of that species.
(e) the limited availability of renewable resources in the environment and the environmental resistance to the biotic potential of the organism.
Answer: (e) the limited availability of renewable resources in the environment and the environmental resistance to the biotic potential of the organism. 
Explanation: The carrying capacity refers to the highest number of the species that the environment can cater for, in terms of food, space and other necessities that supports life.
Thus, the available of renewable resources (i.e resources that can be reused after consumption e.g water) in the environment, plays as a determinant of the highest number of individuals an environment can support (carrying capacity).
Furthermore, environmental resistance to the biotic potential of the organism, is also a determinant of the carrying capacity of organisms inhabiting that particular environment.
