A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
Forest soil has more moisture than sandy soil therefore the types of plants that are grown in soil of forests are more qualitative and more superior than the sandy plants which are facing certain limitations and facing certain situations.
Forest soil supports plant life, but sandy soil does not support any plants. Forest soil produces more superior life and the plants life are found in the forest area and the sandy plants are lesser found in the sandy areas.
The reason for vegetation in forests is because of the supportive factors that are involved in the good plants life. The soil type that is the richest in organic material would be a dark-colored soil. Decaying matter turns brownish-black which makes this type of soil having a dark color even almost black.
Therefore, A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
