Which biome is characterized by permafrost, low temperatures, and sparse vegetation adapted to short growing seasons?
- Tropical Rainforest
- Temperate Deciduous Forest
- Tundra
- Savanna
Show answer
Answer: C. Tundra
Tundra biomes are defined by the presence of permafrost, extremely cold temperatures, and limited vegetation due to short growing seasons and harsh conditions.
Deforestation can lead to increased soil erosion. Which of the following is a direct consequence of increased soil erosion?
- Improved soil fertility
- Reduced sediment load in rivers
- Increased groundwater recharge
- Siltation of reservoirs and water bodies
Show answer
Answer: D. Siltation of reservoirs and water bodies
When soil erodes, it is often carried by water into rivers and reservoirs, leading to siltation, which reduces water storage capacity and can harm aquatic ecosystems.
The 'Temperate Rainforest' biome is characterized by high rainfall and moderate temperatures. Which type of trees typically dominate these forests?
- Drought-resistant succulents
- Grasses and scattered trees
- Large, evergreen coniferous trees
- Deciduous trees that shed leaves seasonally
Show answer
Answer: C. Large, evergreen coniferous trees
Temperate rainforests, often found on coastlines, receive abundant rainfall and have mild temperatures, which support the growth of massive evergreen coniferous trees like redwoods and Douglas firs.
The concept of 'ecotones' refers to:
- Areas with uniform vegetation
- The core of a biome
- Transition zones between two different ecosystems
- Regions entirely devoid of life
Show answer
Answer: C. Transition zones between two different ecosystems
An ecotone is a boundary area or transition zone where two or more ecosystems meet and intergrade, often exhibiting characteristics of both.
Forest fires, while sometimes a natural process, can become destructive when their frequency or intensity is increased by:
- Improved forest management techniques
- Climate change leading to drier conditions
- Increased biodiversity
- Afforestation efforts
Show answer
Answer: B. Climate change leading to drier conditions
Climate change can exacerbate wildfire risk by increasing temperatures and creating prolonged periods of drought, leading to drier vegetation that ignites more easily and burns more intensely.
