What role do herbivores play in aquatic ecosystems?

• A. They are primary consumers that help control algae growth
• B. They compete with carnivores for food
• C. They are primarily decomposers within the environment
• D. They have no significant role

Answer: (A)

Herbivores play a crucial role in aquatic ecosystems as primary consumers. Their primary function is to graze on algae and aquatic plants, which helps to control algae growth. If left unchecked, algal blooms can occur, leading to decreased oxygen levels and negative impacts on water quality and other organisms. By regulating the population of algae, herbivores contribute to a balanced ecosystem, ensuring that resources are efficiently utilized and that energy flows through the food web effectively. This balance is vital for maintaining the health of aquatic ecosystems, as it supports diverse life forms and contributes to habitat stability.
