Question

energy enters an ecosystem as sunlight, is converted by plants into chemical energy, then eventually leaves as heat. which of these best describes energy flow through an ecosystem? a triangular pathway a one - way pathway through the ecosystem completely random a dead - end pathway

Explanation:

The problem is about energy flow in an ecosystem. Energy enters as sunlight, is converted by plants, and leaves as heat. This flow is unidirectional (sunlight → chemical energy → heat), not triangular, random, or a dead - end. A one - way pathway accurately describes this as energy moves in one direction through the ecosystem.

Answer:

B. a one - way pathway through the ecosystem
