Question
Underwater creatures together make marine food web.
- True
- False
Hint:
A food chain or a food web exists in all environmental conditions to ensure the stability of the ecosystem.
The correct answer is 'True'.
- It is true that underwater creatures together make a marine food web.
- The food chain in marine life is almost similar to the terrestrial ones. Here, instead of trees, the producers are phytoplankton and algae. The primary producers are zooplankton or small fishes. These primary consumers are consumed by secondary consumers like fish, small sharks, etc. The top consumers here are usually big sharks, whales, seals, etc.
- There is a close interrelationship between these organisms as one cannot survive without the other.
- Thus, different food chains combine together to form a vast food web.
The underwater food web, being similar to the terrestrial food web is often known as the aquatic food web.

Biomass refers to the overall volume of an organism or the total volume of all the organisms that exist in a given trophic level.
Biomass is often measured through dried organic mass per unit area.

Nutrients are recycled through waste or decomposition in a food web.
Decomposition is a crucial process. It ensures that the nutrients are not lost in the environment.

At each trophic level, most of the energy is lost through biological processes.
Energy always flows in a unidirectional way. It never comes to a downwards trophic level.

If a disease strikes the snake population in the food chain shown, what will happen to the populations of hawks?
At the same time, the population of rabbits in this food chain will increase because there would be no other organism feeding on them.
