_______ have a deep layer of nutrient-rich topsoil.
- a. Deserts
- b. Grasslands
- c. Rain forests
- d. Seamounts
Introduction: Soil encourages biome distribution. Topsoil is the topmost soil layer that contains organic substances and nutrients. Nitrogen, potassium, magnesium, and phosphorous are the main nutrients found in topsoil.
Reason for the correct answer:
Grasslands are rich in nutrients because the grasslands are converted to agricultural use. These are characterized by grasses rather than trees or large shrubs.
Option b. is given as “Grasslands”. Therefore, option b. is correct.
Reasons for the incorrect answers:
Option a. is given as “Deserts”. Deserts have sandy, that is, fast-draining, soil with little topsoil...
