Select correct statement in the following

Options

A. Growth is ultimately limited by carrying capacity
B. When resources are limited growth patten turns exponential
C. Death and emigration increase the size of population
D. Growth becomes unlimited in the absence of competition.

Answer

To solve the question "Select the correct statement," we will analyze each of the provided options based on our understanding of population dynamics, particularly focusing on concepts like carrying capacity, growth patterns, and factors affecting population size.

### Step-by-Step Solution:

1. **Understanding Carrying Capacity**:
- Carrying capacity (denoted as 'K') is the maximum number of individuals of a species that an environment can sustain indefinitely without degrading the habitat.
- In a logistic growth model, the population grows rapidly when resources are abundant but slows down as it approaches the carrying capacity.

**Hint**: Remember that carrying capacity is a crucial concept in ecology that limits population growth.

2. **Evaluating Option 1**:
- The statement "growth is ultimately limited by carrying capacity" is correct because, in a logistic growth model, as the population approaches the carrying capacity, growth slows and eventually stabilizes.
- This means that if resources are limited, the population cannot grow indefinitely.

**Hint**: Think about how resources affect population growth in different models (exponential vs. logistic).

3. **Evaluating Option 2**:
- The statement "when resources are limited, the growth pattern does not turn exponential" is incorrect.
- Exponential growth occurs only when resources are unlimited. When resources are limited, the growth pattern shifts to logistic growth.

**Hint**: Consider the definitions of exponential and logistic growth.

4. **Evaluating Option 3**:
- The statement "death and emigration increase the size of the population" is also incorrect.
- Death decreases the population size, and emigration (individuals leaving a population) also reduces the population size.

**Hint**: Recall the definitions of death and emigration and their effects on population size.

5. **Evaluating Option 4**:
- The statement "growth becomes unlimited in the absence of competition" is incorrect.
- Even in the absence of competition, growth is still limited by factors such as resources, space, and environmental conditions.

**Hint**: Think about other factors that can limit growth besides competition.

### Conclusion:
After evaluating all the options, the correct statement is **Option 1: "growth is ultimately limited by carrying capacity."**
