Soil conservation is
- conversion of sterile soil into fertile one
- aeration of soil
- erosion of soil
- protection against loss.
The Correct Option is D
Approach Solution - 1
Soil conservation is the protection of soil from loss like heavy rainfall, drainage, high wind, flood, draught etc. . This process helps in preventing the soil erosion, degradation and even loss of fertility of soil. This will ensure the high yield and long term productivity of the soil. For example: with the help of crop rotation the fertility of the soil is maintained and also reduces the risk of pest that can degrade the soil and crops.
Approach Solution -2
The Correct Answer is (D)
Real Life Applications
Some real-life examples of soil conservation:
- Cover cropping: It helps to prevent soil erosion by holding the soil in place.
- Contour farming: It helps to prevent soil erosion by reducing the amount of water that runs off the land.
- Strip cropping: It helps to prevent soil erosion by breaking up the flow of water.
- Terracing: It helps to prevent soil erosion by reducing the amount of water that runs off the land and by providing a more level surface for crops to grow on.

Approach Solution -3
Soil is a natural resource that helps in the growth and development of plants. Soil is the uppermost layer of the Earth. This layer comprises the rocks and organic minerals. The soils are classified into 3 types:
- Slit soil
- Clayey soil
- Sandy Soil
Structure of the soil
It is the individual particles of the soil. The structure of the soil are:
- Very fine structure of the soil
- Thick structure
- Very coarse structure
- Medium structure
- Fine structure of soil
Properties of soil
The physical properties of the soil are called density, temperature, colour, structure, texture etc.
Texture: the texture refers to the ratio of minerals and the relative amount of these particles in the soil. Size of silt particles: 0.002 mm to 0.02 mm. Size of sand particles > 0.02 mm
Soil colour: The colour of the soil depends and varies from place to place. It can be brown, yellow and even red. Soil with dark colour absorbs more heat.
Soil conservation
Many human activities lead to the degradation of the quality of the soil, which can lead to soil erosion and also soil pollution. Soil conservation is the technique that helps in the prevention of soil erosion and soil pollution. Soil erosion is mainly responsible for eroding or removing the topmost soil layer. Soil erosion will help in the degradation of quality and fertility of the soil.
Some of the measures are as follows:
- Contour Plowing
- Use of green manures
- Crop rotation
- Salinity management
- Terrace farming

Concepts Used:
Organisms and their Environments
Ecology is the branch of biology that involves the study of the interactions that takes place between an organism and its environment. Any biological organization consists of 4 levels, namely, Organisms, Populations, Biomes, and Communities.
Organisms:
An Organism is an attached living system that lives in an environment. They are able to retain specific behaviours and structure such as bacteria, fungi, plants, animals, and humans. A population is formed by the collection of all these organisms. The collection of population forms a community that helps in the operation of ecosystems.
Environment:
The study of the interaction of organisms in an area with the surrounding environment is Ecology. This interaction constitutes an overall adaptation of the organisms to their environment that also includes the continuity of species.
The environment comprises of both biotic (living things) and abiotic components (non-living things)
Food Chain:
Food Chain is the transfer of food energy from the plant source through a series of organisms that consume and are consumed.
Grass(Producer) → Deer(Herbivore) → Tiger(Carnivore), Grass(Producers) → Insect(Herbivores) → Frog(Carnivores) → Snake(Secondary Carnivore).
Food Web:
Food web is the interlocking pattern of multiple food chains in the ecosystem. In this, many food chains are interconnected and there are increased possibilities of eating and getting eaten by different organisms of various species.
