- B. Most Alpine scrub comprises dry alpine scrub and moist alpine scrub
- C. All of the above
- D. Alpine forests contain Alpine fir birch forest, Rhododendron forest and high level bluepine forests
Explanation: Alpine vegetation is broadly described through alpine scrub, alpine pasture and high-altitude alpine forest communities, with the listed…
Correct answer: All of the above- A. The arid and semi-arid zones of the world, arid savannas of the tropics, the slopes of the mountains of the tropics
- B. And subtropics and forest areas of the developing world under shifting cultivation have been described as 'Fragile Ecosystems'
- C. Because their equilibrium appears to be easily upset and because they become ecologically degraded if certain forms of land use
- D. All of the above
Explanation: Fragile ecosystems include arid and semi-arid regions, tropical and subtropical mountain slopes, savannas and areas under shifting…
Correct answer: All of the above108. The word Soil means:
- A. Natural body which is composed of a mixture of organic and inorganic matter in which plants and other living organism grow
- B. Both (a) & (b)
- C. The unconsolidated mineral material on the surface of earth that serves as natural medium for land plants
- D. None of these
Explanation: Soil may be defined broadly as a natural body containing organic and inorganic matter that supports organisms, or more narrowly as…
Correct answer: Both (a) & (b)- A. Productive capacity
- B. Supporting power
- C. Monitor storage capacity
- D. All of the above
- E. Nutrients availability
Explanation: Physical properties such as texture, structure, porosity and water-holding capacity influence productivity, mechanical support, moisture…
Correct answer: All of the above- A. Water holding capacity
- B. Aeration
- C. Porosity
- D. All of the above
- E. Heat transfer
Explanation: Aggregate structure controls pore spaces, so it affects water retention, air movement, porosity and the transfer of heat through the soil.
Correct answer: All of the above- A. Basis: The classification of soil structure is based on size shape and stability of soil aggregates. The soil aggregate may be of following forms
- B. Major shape: Spheroidal, plate like, bloke like, prism like
- C. None of these
- D. Both (a) & (b)
Explanation: Soil-structure classes are described using aggregate size, shape and stability, with the main forms being spheroidal, platy, blocky and…
Correct answer: Both (a) & (b)- A. Single grained: Where each soil particles function as an individual e.g. Sandy soil
- B. Both (a) & (b)
- C. Massive: Clay fills the spaces and pores so that the soil becomes dense and forms clods
- D. None of these
Explanation: Single-grained soil has separate particles, typical of sand, while massive soil has particles packed together without clear structural…
Correct answer: Both (a) & (b)- A. Key to fertility of soil
- B. Important factor in soil erosion
- C. Both (a) & (b)
- D. None of these
Explanation: Good soil structure supports fertility by improving aeration, water movement and root growth, and it also affects how easily soil is…
Correct answer: Both (a) & (b)- A. Course textured soil (more sand particles)
- B. Medium textured soil (qual proportion of very fine sand, silt and clay)
- C. Fine textured soil (silt and clay)
- D. All of the above
Explanation: Soil texture is commonly grouped as coarse, medium and fine according to the relative amounts of sand, silt and clay.

- B. Larger is size
- C. Have large pores due to which they
- D. Do not retain water/nutrients

Explanation: Silt is intermediate in particle size between sand and clay and feels smooth or powdery when dry.
Correct answer: All of the above- A. Fine textured
- B. Highly plasticity
- C. Have low drainage
- D. All of the above
Explanation: Clay consists of very fine particles, shows high plasticity when wet and usually drains slowly because its pores are small.
