✏️ Part 3: Short Answer Examples

5. Explain how a cactus is adapted to live in the desert.

Sample Answer: Cacti have thick, waxy stems to store water and prevent water loss. They have spines instead of leaves to reduce evaporation. Their roots spread wide to collect rainwater quickly. Some have deep roots to reach underground water.

6. Describe the climate of the tundra biome.

Sample Answer: The tundra is very cold with temperatures often below freezing. It has long, dark winters and short, cool summers. There is little precipitation (rain or snow). The ground stays frozen (permafrost) for most of the year.

7. Why do few trees grow in grassland biomes?

Sample Answer: Grasslands don't have enough rainfall for many trees to survive. The soil may not be deep enough for tree roots. Frequent fires and grazing animals also prevent trees from growing. Grasses are better adapted to these conditions.
