Ans. A region of land where grasses predominate is known as a grassland ecosystem. Savannah is a term used to describe grassland with sporadic trees.
Small herbs, weeds, grass, trefoil, dicotyledonous shrubs, and other leguminous plants make up a grassland ecosystem, which contributes to a high level of preservation.
The grassland habitat is economically significant because it supports the crop of several domesticated and wild animals, including cattle, sheep, goats, ass, pigs, horses, mules, camels, deer, and zebras.
These animals give us transportation, food, milk, and wool.

An attached living system that lives in an environment is commonly known as an organism. These organisms are able to retain certain behaviors and structures. Some examples of organisms are plants, animals, bacteria, fungi, and humans. A group of these organisms leads to the formation of a population. The collection of the population forms a community that assists in the operation of ecosystems.
Each and every organism has the ability to adapt itself to various conditions of the environment. This capacity of organisms is due to their genetic variations. It is due to this only that their probability of survival get increases. For instance, camels adapt themselves to survive in desert areas and polar bears adapt to the extreme cold conditions or situations through their dense fur coat.
A collection of organisms or individuals of a species that live, at a specific time, in a geographical area that is well-defined and capable of interbreeding is described as a population.
