Which of the following events would decrease competition for resources in an ecosystem?

• A. An increase in the population of a predator species
• B. A decrease in the availability of water
• C. A decrease in the number of plant species
• D. An increase in the population of a herbivore species

Answer: (A)

Verified step by step guidance

1. Understand the concept of competition in an ecosystem: Competition occurs when organisms vie for the same resources, such as food, water, or space, which are limited in supply.
2. Analyze the impact of an increase in the population of a predator species: Predators can control the population of prey species, potentially reducing competition among prey for resources.
3. Consider the effect of a decrease in the availability of water: Limited water resources can increase competition among organisms that rely on water for survival.
4. Evaluate the consequences of a decrease in the number of plant species: Fewer plant species can lead to reduced food availability for herbivores, increasing competition among them.
5. Assess the impact of an increase in the population of a herbivore species: More herbivores can lead to increased competition for plant resources, as they all rely on plants for food.
