Answers
Explanation:
a)Soil can be defined as the organic and inorganic materials on the surface of the earth that provide the medium for plant growth. Soil develops slowly over time and is composed of many different materials
3 a. Soil- Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water.
b. Leaching- In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
c. Resource- Resource is defined as a substance that is required by a living organism for normal growth, maintenance, and reproduction (see biological resource). The main essential resources for animals are food, water, and territory.
d. Conservation is the protection of things found in nature. It requires the sensible use of all Earth's natural resources: water, soil, minerals, wildlife, and forests. People who care about conservation try to preserve natural resources so they will still be around in the future.
