What is the role of herbivores in an ecosystem?

• Herbivores only eat meat

Why are producers essential for an ecosystem?

• Producers convert sunlight into energy through photosynthesis, which is essential for the ecosystem.

• Producers do not contribute to the oxygen cycle

• Producers consume energy from the ecosystem

• Producers are not involved in the food chain

What is the primary source of energy in most ecosystems?
