Basic Energy Management Questions and Answers on “Grassland Ecosystems”.
1. What is the predominate vegetation in grassland ecosystem?
a) Sand
b) Land
c) Rock
d) Grass
Answer: d
Clarification: Grassland ecosystem includes a wide range of landscapes in which the vegetation is predominantly grass and small annual plants specifically adapted to India’s climatic conditions. Due to the high presence of grass vegetation it got its name as Grassland ecosystem.

a) Aquatic ecosystem
b) Desert ecosystem
c) Grassland ecosystem
d) Forest ecosystem
Answer: c
Clarification: Grasslands form a variety of ecosystems located in different climatic conditions. It ranges from near desert conditions to patches of shoal grasslands that occur on hill-slopes. In the Himalayas, there are high cold pastures.
5. Where we can find tracts of tall elephant grass?
a) Terai belt
b) Deccan belt
c) Himalayan pasture belt
d) Gangs belt
Answer: a
Clarification: Tracts of tall elephant grass present in the low lying terai belt south of the Himalayan foothills. This is one of the types of grassland which is found in India. They form variety of ecosystems based on climatic conditions.
6. Himalayan wildlife requires both forest and grassland ecosystems.
a) True
b) False
Answer: a
Clarification: Himalayan Wildlife requires both ecosystems. They want forest as well as grassland ecosystem as vital parts of their habitat. The animal migrates up into the high altitude grasslands in the summer season. In winter they move downwards.
7. What is the type of grassland ecosystem which is found at Western India, Central India and the Deccan?
a) The semi-arid plains
b) The terai
c) The Himalayan pasture belt
d) The shola
Answer: a
Clarification: The semi-arid plains of Western India, Central India and the Deccan are covered by grassland tracts with patches of thorn forest. Several mammals such as blackbuck, chinkara and birds such as bustards and floricans are adapted to this condition.
8. Which of the following consist of patches on hill slopes?
a) The shola grassland
b) Desert
c) Himalayan region
d) Deccan pasture land
Answer: a
Clarification: The shola grasslands consist of patches on hill slopes that occur alongside the shola forests on the Western Ghats and the Anamalai ranges. These form patchworks of grassland on the slopes and forest habitats along the streams.

10. What is stored to feed cattle if there is no grass during summer to cattle?
a) Vegetables
b) Chemical manures
c) Fodder
d) Water
Answer: c
Clarification: Grassland is used to graze cattle. Fodder is collected and stored to feed cattle when there is no grass left for them to graze in summer. Sometimes grassland ecosystem won’t give healthy grass due to climatic changes.
11. How grassland converted into flat stubs?
a) By over grazing
b) By less grazing
c) By climatic changes
d) By less water
Answer: a
Clarification: When animals over graze, the grasses are converted into flat stubs with very little green matter left in the land. Degraded grasslands have fewer grass species as the nutritious species which are used by the large number of domestic animals.
12. How many percent of grassland covered in terms of permanent pastures in India?
a) 2.7%
b) 3.7%
c) 4.7%

13. Why rotational grazing pattern established?
a) To preserve grassland ecosystem
b) To destroy grassland ecosystem
c) To graze in the tropical rain forests
d) To grow grass in grassland ecosystem
Answer: a
Clarification: In order to close a part of the grassland in an area every year, the rotational grazing pattern is established. Grasslands should be over grazed and some areas should be closed for grazing the live stock.
