Soil moisture is limited in the grassland ecosystem because of:
Correct answer: A. Low precipitation, High evaporation
- A. Low precipitation, High evaporation
- B. Low precipitation, Low evaporation
- C. High precipitation, Low evaporation
- D. High precipitation, High evaporation
Explanation
Grassland ecosystems often experience low precipitation and high evaporation, which together contribute to limited soil moisture. The low rainfall means there is not enough water input to compensate for the high rate of water loss due to evaporation. Option A correctly identifies this combination, leading to limited soil moisture.Option B is incorrect because while low precipitation would reduce soil moisture, low evaporation would retain some of it. Option C is incorrect because high precipitation would increase soil moisture, and low evaporation would conserve it. Option D is incorrect because high precipitation would generally increase soil moisture, even though high evaporation is present.

About Ecosystems
An ecosystem consists of organisms interacting with one another and with abiotic factors such as light, water, soil and temperature. The topic covers populations and communities, food chains and webs, trophic levels, ecological pyramids, energy flow, nutrient cycles and ecological succession.
