Verified step by step guidance1
Understand the concept of energy flow in ecosystems: Energy in ecosystems originates from the sun, which is captured by producers (plants, algae, etc.) through photosynthesis. Producers convert sunlight into chemical energy stored in organic molecules.
Recognize the role of producers: Producers are the base of the food chain and provide energy to herbivores (primary consumers) when they consume plants.
Identify the role of herbivores: Herbivores consume producers and transfer the energy stored in plants to the next level of the food chain, which includes carnivores (secondary consumers).
Understand the role of carnivores: Carnivores obtain their energy by consuming herbivores, which indirectly links their energy source back to producers and ultimately sunlight.
Conclude that the initial source of energy for a carnivore is sunlight, as it is the origin of energy captured by producers and passed through the food chain.
