Practice questions
Q1Consider the following statements about vegetation restoration: 1. A monoculture plantation is not the same as a natural forest. 2. Natural grasslands and savannas are empty lands automatically suitable for tree planting. 3. An increase in tree cover does not by itself prove recovery of native biodiversity or old-growth forest functions. Select the correct answer using the code given below:
Statements 1 and 3 are correct. Plantation, tree-cover and natural-forest measures describe different ecological conditions, so more tree cover alone does not establish native ecosystem recovery. Statement 2 is incorrect because natural grasslands and savannas are ecosystems, and inappropriate tree planting can damage them.
Q2For identifying a climatic region on a map, consider the following analytical steps: (a) Identify the resulting vegetation response. (b) Locate the region latitudinally. (c) Identify the modifying ocean current or relief barrier. (d) Identify the pressure-wind belt affecting the region. Arrange the steps from the broadest climate control to the resulting ecological response and select the correct answer using the code given below:
From the broadest climate control to the resulting ecological response, first locate the region by latitude, identify the pressure-wind belt, check the modifying ocean current or relief barrier, and then infer the vegetation response. Thus the order is b-d-c-a, shown in option D.
Q3Match List I with List II and select the correct answer using the code given below: List I (a) Equatorial rainforest (b) Mediterranean (c) Taiga (d) Tundra List II 1. Coniferous forest 2. Dense evergreen multi-layer forest 3. Mosses, lichens and dwarf shrubs 4. Hard-leaved shrubs and woodland
Equatorial rainforest has a dense evergreen multi-layer structure; Mediterranean climate supports hard-leaved shrubs and woodland; taiga is coniferous forest; and tundra supports mosses, lichens and dwarf shrubs. Thus option C contains the complete correct match.
Q4Consider the following statements about vegetation adaptations and soils: 1. High biomass in an equatorial rainforest does not necessarily mean that its exposed soil is highly fertile. 2. Needle leaves in taiga help reduce water loss and snow load. 3. Deciduous forests are dead during dry or cold months. Select the correct answer using the code given below:
Statements 1 and 2 are correct. In equatorial forests, nutrients are often held in living biomass and rapidly recycled, so exposed soil need not be highly fertile. Taiga needle leaves reduce water loss and snow load. Statement 3 is incorrect because seasonal leaf fall conserves water or avoids frost damage; it does not mean the forest is dead.
Q5Consider the following statements about tundra environments: 1. Permafrost can restrict both drainage and root depth. 2. Alpine tundra is caused by high latitude rather than altitude. Which one of the following is correct?
Statement 1 is correct because permafrost limits drainage and the depth available to roots. Statement 2 is incorrect: alpine tundra may resemble polar tundra in its low vegetation, but altitude, not high latitude, causes the alpine setting.

7Consider the following statements about the effect of ocean currents on coastal climates: 1. Warm ocean currents can raise coastal moisture and soften winters. 2. Cold ocean currents necessarily prevent fog from forming along adjacent coasts. Which one of the following is correct?
8A tropical mountain may show the following vegetation zones: (a) Alpine meadow (b) Rainforest foothills (c) Permanent snow (d) Temperate forest Arrange them in the correct order from the foothills upward and select the correct answer using the code given below:
9With reference to dry climates, consider the following statements: 1. A desert is defined by moisture deficit rather than by high temperature alone. 2. Cold ocean currents can help produce foggy coastal deserts. 3. Aridity, drought and desertification are synonymous terms. Select the correct answer using the code given below:
