[A]: Environment resistance does not limit population growth.
[R]: Environment resistance decreases as a population approaches the environment's carrying capacity

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not the correct explanation of A
C. If A is true and R is false
D. If both A and R are false

Answer

To solve the question, we need to analyze both the assertion and the reason statements provided:

### Step 1: Understand the Assertion
The assertion states: "Environment resistance does not limit population growth."
- **Analysis**: Environmental resistance refers to factors that limit the growth of a population, such as food shortages, disease, predation, and natural calamities. These factors indeed impose checks on population size. Therefore, the assertion is **false** because environmental resistance does limit population growth.

### Step 2: Understand the Reason
The reason states: "Environment resistance decreases as a population approaches the environment's carrying capacity."
- **Analysis**: Carrying capacity is the maximum population size that an environment can sustain. As a population approaches this capacity, competition for resources increases, leading to greater environmental resistance, not a decrease. Thus, the reason is also **false**.

### Step 3: Conclusion
Since both the assertion and the reason are false, the correct answer to the question is that both statements are false.

### Final Answer
Both assertion and reason are false.
