• B. They regulate the population of herbivores.
• C. They convert solar energy into chemical energy through photosynthesis.
• D. They decompose organic matter to recycle nutrients.

Answer: (C)

Verified step by step guidance

1. Understand the concept of producers in an ecosystem: Producers, also known as autotrophs, are organisms that can produce their own food using light, water, carbon dioxide, or other chemicals.
2. Recognize the process of photosynthesis: Producers, primarily plants, algae, and some bacteria, use photosynthesis to convert solar energy into chemical energy. This process involves the transformation of light energy into glucose, a form of chemical energy.
3. Identify the role of producers in energy flow: Producers form the base of the food chain in an ecosystem. They provide energy for all other organisms, including herbivores, carnivores, and decomposers, by converting solar energy into a form that can be consumed.
4. Differentiate producers from other roles: Unlike consumers, producers do not obtain energy by consuming other organisms. Instead, they are the source of energy for consumers.
5. Clarify the importance of producers in nutrient cycling: While producers are not primarily responsible for decomposing organic matter, they play a crucial role in the carbon cycle by fixing carbon dioxide into organic compounds during photosynthesis.
