Soil influences plant distribution through its pH, nutrient content and:
ADepth of the water table
BParticle size structure
CAnnual sunshine hours
DDistance from the sea
Answer & Solution
Correct answer: B. Particle size structure
1. Plants draw water and minerals through their roots, so the medium matters.
2. Soil structure, meaning the particle size of soil components, plays an important role in the distribution of plants.
3. Soil pH and soil nutrient content play that role alongside it.
4. Because animal distributions are related to the distribution of what they eat, soil ends up shaping animal ranges too.
5. Sunshine hours and coastal distance act through climate rather than through the soil itself.
