Q1. Red Data Book contains a record of:
A) All animals
B) All plants
C) Endangered species
D) Extinct species
Answer
Endangered species
Concept
The Red Data Book is an important reference that provides information about species facing a high risk of extinction.
Explanation
The Red Data Book maintains records of endangered species of plants and animals. It helps scientists, governments, and conservation organizations monitor species whose populations are declining and develop strategies for their protection.
Exam Focus
Remember:
Red Data Book → Record of Endangered Species
Q2. Migration is the phenomenon of movement of species from its own habitat to some other habitat for a particular:
A) Shelter
B) All of these
C) Food
D) Period of time
Answer
Period of time
Concept
Migration is a seasonal movement of animals from one place to another.
Explanation
Migration refers to the movement of animals from their natural habitat to another region for a particular period of time. This movement usually occurs in search of favourable climatic conditions, breeding grounds, or food, after which many species return to their original habitat.
Exam Focus
Remember:
Migration → Seasonal movement for a particular period.
Q3. Deforestation means:
A) Saving wildlife
B) Clearing of forests
C) Planting trees
D) Cleaning the environment
Answer
Clearing of forests
Concept
Deforestation refers to the removal of forests on a large scale.
Explanation
Deforestation is the process of cutting down or clearing forests for purposes such as agriculture, urban development, mining, or industrial activities. Excessive deforestation causes habitat loss, soil erosion, climate change, and a decline in biodiversity.
Exam Focus
Remember:
Deforestation = Large-scale clearing of forests.
Q4. Species found exclusively in a particular area are called:
A) Migratory species
B) Endangered species
C) Extinct species
D) Endemic species
Answer
Endemic species
Concept
Some species naturally occur only within a specific geographical region.
Explanation
Endemic species are plants or animals that are naturally found only in a particular area and nowhere else in the world. These species are often highly sensitive to habitat destruction and environmental changes.
Exam Focus
Remember:
Endemic Species → Found only in one specific region.
Q5. Reforestation is:
A) Cutting of trees
B) None of these
C) Using forest land for agriculture
D) Stocking of destroyed forests by planting new trees
Answer
Stocking of destroyed forests by planting new trees
Concept
Reforestation is an important method of restoring damaged forest ecosystems.
Explanation
Reforestation is the process of planting new trees in areas where forests have been destroyed or heavily degraded. It helps restore biodiversity, improve soil quality, conserve water resources, and reduce the effects of climate change.
Exam Focus
Remember:
Reforestation → Planting trees to restore destroyed forests.
Important Concepts
1. Red Data Book
- Contains records of endangered plant and animal species.
- Helps in conservation planning.
2. Endangered Species
- Species whose population has declined significantly.
- Require immediate conservation efforts.
3. Migration
- Seasonal movement of animals.
- Occurs for food, breeding, or suitable climatic conditions.
4. Deforestation
Major causes:
- Agriculture
- Urbanisation
- Mining
- Industrial development
Effects:
- Loss of biodiversity
- Soil erosion
- Global warming
- Habitat destruction
5. Endemic Species
- Found only in a specific geographical area.
- Require protection to prevent extinction.
6. Reforestation
Benefits:
- Restores forests
- Conserves biodiversity
- Prevents soil erosion
- Improves environmental balance
