Question

Name the type of food chain that exists in a pond.

Answer 1

The ecosystem is divided into two sub-categories that are terrestrial and aquatic ecosystems. The terrestrial ecosystem may include forests, deserts, and grasslands. The aquatic ecosystem included ponds, sea, river, etc.

Complete answer:
The ecosystem is an interaction between the biotic that includes all the living organisms and abiotic components such as water, air, light, etc. The biotic components interact among themselves and also with the physical environment surrounded by them. Both the biotic and abiotic components are interconnecting with each other.
In the food chain, the flow of energy and the flow of nutrition takes place. Each level in the food chain is called a trophic level. So the food chain is transferring energy and nutrients from one trophic level to another trophic level. There are four kinds of levels in a food chain: they are producers, primary consumers, secondary consumers, and tertiary consumers. The first trophic level that is producers includes all the autotrophs such as plants and grasses. The next is primary consumers include the carnivores followed by the secondary consumers includes all the carnivores animals. The last trophic level that is tertiary consumers is composed of decomposers and scavengers.
A pond is a freshwater aquatic ecosystem. The type of food chain that exists in a pond is called the grazing food chain. In a pond, the producers are phytoplankton like some algae and submerged plants found at the edges. The consumers have included zooplankton and the last decomposers are some bacteria, fungi, etc found at the bottom of the pond.
For example Algae or waterweed →zooplankton → fish → kingfisher/shark/human

Note: The ecosystem can be artificial also. The ecosystem made by man or human is called an artificial ecosystem. For example, a crop field, an aquarium, garden, etc are common examples of an artificial ecosystem.
