Q. Consider the following statements regarding the Desert Ecosystem:
1.Some desert plants perform photosynthesis through their stems due to absence or reduction of leaves.
2.Desert animals conserve water by producing dilute urine and being active primarily during the day.
3.In deserts, perennial plants like creosote bush and cactus are common, while annuals complete their life cycle only during the short rainy season.
Which of the statements given above are correct?
Answer: B
Notes:
Explanation:
- Many desert plants reduce water loss by minimizing leaves and conducting photosynthesis through chlorophyll-rich stems.
- Desert animals conserve water by excreting concentrated urine, not dilute. They are mostly nocturnal, not active during the day.
- Creosote bush and cactus are perennial desert plants, while annuals bloom and reproduce during brief rainy seasons
