Verified step by step guidance1
Understand the concept of energy flow in living systems: Energy originates from the Sun, which is the primary source of energy for most ecosystems. Producers (like plants) capture this energy through photosynthesis.
Recognize the role of producers: Producers convert solar energy into chemical energy stored in glucose and other organic molecules. This energy is then available to other organisms in the ecosystem.
Identify the role of consumers: Consumers (herbivores, carnivores, and omnivores) obtain energy by eating producers or other consumers. This represents the transfer of energy through the food chain.
Understand the role of decomposers: Decomposers (like fungi and bacteria) break down dead organisms and organic waste, recycling nutrients back into the ecosystem. They play a crucial role in maintaining ecosystem balance.
Sequence the flow of energy: The correct sequence is Sun → Producers → Consumers → Decomposers, as energy flows from the Sun to producers, then to consumers, and finally to decomposers in the ecosystem.
