• D. Energy is stored indefinitely in the ecosystem.

Answer: (A)

Verified step by step guidance

1. Understand the concept of energy flow in an ecosystem: Energy flow refers to the transfer of energy through a food chain, starting from the sun and moving through producers, consumers, and decomposers.
2. Identify the role of producers: Producers, such as plants, convert solar energy into chemical energy through photosynthesis. This energy is then available to consumers.
3. Examine the role of consumers: Consumers, such as herbivores and carnivores, obtain energy by eating producers or other consumers. This energy transfer is unidirectional, moving from producers to consumers.
4. Clarify the concept of energy recycling: Unlike matter, energy is not recycled in ecosystems. It flows in one direction and is eventually lost as heat due to metabolic processes.
5. Consider the storage of energy: Energy is not stored indefinitely in ecosystems. It is continuously used and dissipated, emphasizing the one-way flow from producers to consumers.
