Each environment can support a limited number of individuals of a population depending upon:

Options

A. Biotic potential
B. Natality
C. Reproductive potential
D. Carrying capacity

Explanation

To answer the question regarding what determines the limited number of individuals a population can support in an environment, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Carrying Capacity**:
- Carrying capacity is defined as the maximum population size of a species that an environment can sustain indefinitely without being degraded. This concept is crucial in understanding population dynamics.

2. **Identifying Key Factors**:
- The carrying capacity of an environment is influenced by several factors, primarily the availability of resources. These resources include food, water, shelter, and space.

3. **Biotic Potential vs. Carrying Capacity**:
- Biotic potential refers to the maximum reproductive capacity of an organism under optimal environmental conditions. However, this does not take into account the limitations imposed by the environment.
- Natality, or birth rate, indicates the number of births in a population but does not directly affect the environmental limits.

4. **Resource Availability**:
- The carrying capacity is directly related to the resources available in the environment. If resources are abundant, the carrying capacity increases; if they are limited, the carrying capacity decreases.

5. **Conclusion**:
- Therefore, the limited number of individuals that an environment can support depends primarily on its carrying capacity, which is determined by the availability of essential resources.

### Final Answer:
The limited number of individuals of a population that an environment can support depends on its **carrying capacity**, which is influenced by the availability of resources like food, water, and habitat.
