What do you think the common characteristics in the above two habitats?

The answer to this questions is that both habitats have living and non-living
components. These are common to all habitats. However, the kinds of
plants and animals (living beings) are different, and the non-living
components also vary.

The living beings in a habitat are called biotic components , and the non-
living things are called abiotic components .

What is the reason that some organisms live in water and others on land? It
is so because every organism requires specific conditions to survive. From

this activity, you can understand that different habitats provide different
kinds of living conditions.

Let us know about survival of fish in a pond.
In Activity 1, you listed fish as a biotic component of a pond. A pond
supports fish by providing necessary living conditions – food, oxygen,

shelter, and space to grow. Fish get food from small plants and animals, and
oxygen from the water itself.

Many other living beings are also a part of a pond. Some of these are frogs,
freshwater turtles, snakes, dragonflies, mosquitoes, snails, and ducks. Also
plants like algae, diatoms, duckweed, and lotus are found in a pond. All
these organisms interact with one another and with the non- living parts of
the pond.
