Answer :
Answer:
B. sun → algae → fish → hawk
Explanation:
The sun is the main source of energy in an ecosystem, providing light that allows photosynthesis to take place and be consumed by plants and algae. In this case, as producers, algae acquire solar energy and convert it into chemical energy through photosynthesis; fish feed on algae as primary consumers— gaining energy and nutrients from them. The same fish then become prey for secondary consumers like hawks who acquire energy by eating the fish. This depicts the sequence of transfer from the sun to producers to consumers — showing how all living organisms are interrelated in ecosystems' web of life. The contribution each organism makes towards keeping balance in the ecosystem functioning highlights that every organism has a role to play within an ecosystem.
