Open in App
Solution
Dear Student, Aquatic food chain can be represented as:
Small algae (Phytoplanktons) → Protozoa (Zooplanktons)→ Small Insects→ Small fish → Large fish.
The energy flow occurs form sun to the tertiary consumer according to 10% law i.e only 10 % energy is transferred form one tropic level to other level.
Sun → Small algae (Phytoplanktons) → Protozoa (Zooplanktons)→ Small Insects→ Small fish → Large fish.
All the dead organisms are decomposed by decomposers that release minerals and energy back in the surroundings.
