• A. Uniform dispersion
• B. Random dispersion
• C. Clumped dispersion

Answer: (A)

Verified step by step guidance

1. Understand the concept of population dispersion patterns: Population dispersion refers to the way individuals in a population are spaced within a given area. The three main types are uniform, random, and clumped dispersion.
2. Define uniform dispersion: In uniform dispersion, individuals are evenly spaced, often due to competition for resources such as water, nutrients, or sunlight. This pattern minimizes overlap and ensures each individual has access to sufficient resources.
3. Consider the environmental context: Desert plants often face limited water availability, which leads to competition. To maximize access to rainwater, these plants tend to grow in a way that avoids crowding, resulting in a uniform dispersion pattern.
4. Compare with other dispersion patterns: Random dispersion occurs when individuals are spaced unpredictably, often in environments with abundant resources. Clumped dispersion happens when individuals group together, typically around resources or due to social behavior. Neither of these patterns fits the scenario of desert plants competing for rainwater.
5. Conclude that uniform dispersion is the most likely pattern for desert plants widely spaced due to competition for rainwater, as this arrangement optimizes resource use and minimizes competition.
