Answer:

1. True

Living organisms present in soil include archaea, bacteria, actinomycetes, fungi, algae, protozoa, and a wide variety of larger soil fauna, including springtails, mites, nematodes, earthworms, ants, insects that spend all or part of their life underground, and larger organisms such as burrowing rodents.

2. True

We literally can't live without it  Soil without life is dirt, a sterile substrate. Scientists have found that the world's soil is one of our largest reservoirs of biodiversity, containing almost one-third of all the planet's life! A teaspoon of soil alone may be home to billions of microbes.

3. True

The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water. Conversely, sands provide easier passage or transmission of water through the profile.

4. Soils with a dark brown to black color are usually high in humus content. The dark color of humus helps to warm up cold soils in the spring. Humus is like a big sponge that can hold up to 90% of it's weight in water.

5. When we sprinkle water on the ground, it is soon absorbed by the soil. This is because water percolates through the soil. The process in which water passes down slowly through the sol is called percolation of water. But water does not percolate at the same rate in all types of soils.

6. Water does not drain quickly through clayey soil because of less space among particles. So, clayey soil is not well aerated and retains more water. ... Loamy Soil: Particles of loamy soil are smaller than sand and larger than clay. Loamy soil is the mixture of sandy soil, clayey soil and silt.

7. Sandy soil is not fit for vegetation as it does not retain water. ... as water requires more water , it needs soils which retain water .

8. True

Without plant cover, erosion can occur and sweep the land into rivers. The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion.
