Biology Question on Eco-System
Which of the following option determines percolation and water holding capacity of soils ?
A
Climate
B
Grain size, soil composition and aggregation
C
Weathering process
D
Soil development
Answer
Grain size, soil composition and aggregation
Explanation
Solution
The correct option is(B): Grain size, soil composition and aggregation.
The option that determines percolation and water holding capacity of soils is "Grain size, soil composition, and aggregation." These factors affect the pore spaces within the soil, which in turn influence the movement of water through the soil and its ability to retain water. Climate, weathering process, and soil development also play important roles in soil characteristics, but they may not directly determine percolation and water holding capacity.
