How does a guppy help an ecosystem?

Guppies play a vital role in their ecosystems by serving as both prey and predator. As small herbivores, they help control algae growth in freshwater habitats, promoting water quality and plant health. Additionally, guppies are a food source for larger fish and wildlife, contributing to the food web's balance. Their reproductive capacity also helps maintain population dynamics, influencing the overall biodiversity in their environment.
