An ecosystem is a geographic area where plants, animals, and other organisms interact with each other and their environment. Grassland ecosystems are dominated by grasses and found in areas with distinct wet and dry seasons where rainfall is insufficient for tree growth. They occupy 20% of the Earth's land and support livestock grazing and soil/water conservation. Grassland ecosystems contain biotic factors like plants and animals as well as abiotic factors like nutrients. They are productive, providing habitat and food, and rely on nutrient cycling between organisms.

2. What is
Ecosystem?
An ecosystem is a geographic area where plants, animals, and other
organisms, as well as weather and landscape, work together to form
a bubble of life. Ecosystems contain biotic or living, parts, as well as
abiotic factors, or nonliving parts. Biotic factors include plants,
animals, and other organisms.

3. What is Grassland ecosystem?
Grasslands are the areas that are dominated by a nearly
continuous cover of grasses.
It is one of the most widespread of all major vegetation in the
world.
They occupy about 20% of the land on the surface of the earth.
Grasslands are found in both tropical and temperate regions
where rainfall is not enough to support the growth of trees.

4. What is
Grassland ecosystem?
They are also found in areas consisting of well-defined hot, dry,
warm, and rainy seasons.
In India, they are found mainly high Himalayas. The rest of
India’s grasslands are mainly composed of the Steppes and
Savana. Steppe formations occupy large areas of sandy and
saline soils.

5. Components of Grassland Ecosystem
These are non-living thing components consist of carbon,
hydrogen, sulphur, nitrogen and phosphorous etc.
1.Abiotic Components
These are living components and their sub-components

6. Functions of the Grassland Ecosystem
The primary function of an ecosystem is productivity.
The producers fix the solar energy and produce the complex organic
matter with the help of minerals.
It provides forage for livestock, protection and conservation of soil
and water resources, furnishing a habitat for wildlife, both flora
and fauna and (contribution to the attractiveness of the landscape.

7. Functions of the Grassland Ecosystem
There is an important feature of the ecosystem that one
level of an organism serves as food for another level of the
organism
1. Food Chain in an ecosystem
For any ecosystem to be successful, it is important
that the constituent materials move in a cyclic
manner.
2. Nutrient cycle in an ecosystem

8. Economic importance of Grassland Ecosystem
Grasslands are the grazing areas of many rural communities.
Farmers who keep cattle or goats, as well as shepherds who keep
sheep, are highly dependent on grasslands.
The grass is also used to thatch houses and farm sheds.
Grasslands have diverse species of insects that pollinate crops.
There are also predators of these insects such as small mammals
like shrews, reptiles like lizards, birds of prey, and amphibia such
as frogs and toads.
