A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.

The Nature of Soil:

We walk on soil. We grow crops, trees, gardens, and lawns in soil. It is all around us, and it is obviously important to our well - being. Yet, most people don’t give soil a second thought, and few people know what makes up soil.

Soil and Its Value:

• Soil is the outermost layer of the earth’s crust. Depending on where you are on Earth, the layer of soil may be several inches thick or many feet deep.
• Soil is a complex material that sup-ports life. It may take a thousand years for just 1 inch of soil to form. Therefore, managing soil properly for the benefit of future generations is critical.

Mineral Matter::

• Mineral matter is inorganic material. Mineral matter began as rock.
• Soil generally has mineral particles of different sizes. These particles are labeled sand, silt, or clay, based on their size. Sand is the largest soil particle. Silt is the mid-size soil particle. Clay is the smallest soil particle.

Organic Matter:

• Organic matter, which accounts for about 5 percent of the soil, is partially decomposed plant and animal matter.
• The Most organic matter is from plant leaves, roots, and stems. Organic matter gives soil its dark color. Organic matter improves aeration and water- holding capacity and contributes to the soil’s fertility.

Hence, Option C is correct Answer.

The correct statements are:

A. The biosphere is the important zone of contact between the land, water and air

B. Everything in the biosphere is interconnected and interdependent

Hence the correct option is C.

The biosphere is the thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. It is composed of living organisms and nonliving factors from which the organisms derive energy and nutrients.

What is Biosphere?

• The biosphere is the region of the earth where life can exist and grow. It is the part of the planet where life is capable of existing.
• The biosphere is also known as the Ecosphere, which means the constitution of all the ecosystems exists worldwide.
• According to some definitions, the biosphere is practically a closed structure in terms of matter, with few inputs and outputs. It is an open system that uses photosynthesis to absorb solar energy at a rate of about 130 Terawatts per year.

What are Biosphere and Its Components?

• Earth was a barren planet with shallow seas and a thin band of gases before life appeared there.
• These gases were primarily Carbon dioxide, Carbon monoxide, Nitrogen, Hydrogen sulfide, and water vapor.
• he planet was hostile and barren. The lithosphere (rock and soil), hydrosphere (water), and atmosphere make up this entirely inorganic state of Earth, which is known as the geosphere (the air).

What is the Importance of the Biosphere?

• The interactions between living things and their environment are connected by the biosphere. The lives of living things can be greatly affected by a small alteration in the environment. The biosphere is crucial for all life because of this relationship, though.

Following is a list of some of them:

• The ecosystem required for survival is provided by the biosphere. The biosphere’s climate is something that living things should be able to adapt to. Ecosystems support biodiversity, and the biosphere provides a dependable source of nutrition for all life on Earth. The term “biodiversity” refers to biological variation.
• Biosphere reserves are restricted places for the preservation of flora and fauna. Additionally, it contributes in maintaining the traditional way of living of the local tribes. They guard the biodiversity of the area. The greatest level of the ecological structure is the biosphere. It includes each type of species and every biome on the planet.
• The biosphere supports life on Earth by contributing to the management of the hydrological (water) cycle, soil health, and composition of the atmosphere. The biosphere is a small area of the earth’s surface where soil, water, and air work together to support life. Only in this region is life possible.

Examples of Biosphere

• The part of the world where living creatures reside is known as the biosphere, which also includes the air and the surface of the planet. The area where life exists on, above, and below the surface of the Earth is referred to as the biosphere. the region of the planet that is naturally home to life, which extends from the deep crust to the lower atmosphere.
• The biosphere also referred to as the ecosphere, is the dynamic, unknown biological skin of the planet. It is where living things naturally live. It is composed of the hydrosphere, the lower atmosphere, and the surface of the lithosphere.
• The entire ecological system of the planet is known as the biosphere. It includes every type of life that exists on Earth as well as every habitat that can support life. The biosphere is made up of numerous biomes. These regions have particular climatic conditions, flora, fauna, and adaptation requirements in order to survive.

Hence, Option Correct is A.
