Explain the role played by predators in a community.

Explanation

### Step-by-Step Solution:

1. **Definition of Predators**: Predators are organisms that hunt and kill other organisms (prey) for food. They play a crucial role in the ecosystem by influencing the population dynamics of the species they prey upon.

2. **Population Control**: One of the primary roles of predators in a community is to keep the population of prey species under control. By preying on weaker or more abundant individuals, predators help prevent overpopulation, which can lead to resource depletion.

3. **Species Diversity Maintenance**: Predators contribute to maintaining species diversity within a community. By controlling the population of dominant prey species, they reduce competition among various species. This allows for a wider variety of species to coexist, as no single species can monopolize resources.
