Question

Explain the components of Pond eco-system.

Accepted Answer

A pond ecosystem refers to the freshwater ecosystem where there are communities of organisms that are dependent on each other and the prevailing water environment for their nutrients and survival. Usually, ponds are shallow (hardly 12 – 15 feet) water bodies in which sunlight can reach to its bottom, permitting the growth of the plants that grow there.

The pond ecosystem is a complex interaction between the abiotic and biotic components.
Producers:
These are the aquatic green plants, which may be divided into two groups.

Phytoplanktons: These are microscopic autotrophs, which make solar energy. Ex. Spirogyra, Volvox, Oedogonium.

Macrophytes: These are large plants, which make complex food. They are of the following types

Submerged plants: These are submerged in water, are submerged plants are Hydrilla and Utricularia.

Floating plants: These are floated freely on the water surface are called floating plants Ex. Pistia, Nymphea.

Consumers:
The consumers are those heterotrophic organisms, which consume producers as food. They are also following types of Primary consumers: These herbivores depend upon autotrophic organisms such as microscopic plant eaters or zooplanktons, Mollusks, Beetles, Cyclops, and Daphnia etc.

Decomposers:
These include heterotrophic microbes such as bacteria, fungi, which are broken down the organic complex food from stagnant producers and consumers into simple inorganic compounds made possible to the producers.

Based on water depth and types of vegetation and animals, there may be three zones in a lake or pond. The different zones are as follows:
Littoral zone – It is the shallow water region that is usually occupied by rooted plants.
Limnetic-zone - It ranges from the shallow to the depth of effective light penetration and associated organisms are small crustaceans, rotifers, insects, and their larvae and algae.
Pro-fundal zone - It is the deep-water part where there is no effective light penetration. The associated organism are mussels, crabs, worms etc.
