Every living creature in the world needs a place to live its life and reproduce. Such places are called habitats.
There are two major types of habitats such as:
- Aquatic habitat
- Terrestrial habitat
Aquatic habitat
"Aqua" means "water".
Habitats filled with water are called aquatic habitats.
If the water is fresh water then it is called fresh water habitat. If the aquatic habitat has marine or salt water then it is called marine habitat.
Fresh water habitat
Plants that live in fresh water habitat develop some special adaptations. Since the plants need to float in the fresh water pond or lake, the stems and leaves of the aquatic plants have air chambers.
Fresh water plants include water hyacinth, lilly, lotus. Victoria Amazonia is a fresh water plant which has a floating leaf so brad that it can withstand a weight of 45 kilograms.
Example:
Fresh water habitats include rivers, lakes, pools and ponds.
