What is cellular respiration?
The process of breakdown of food in the cell with the release of energy is called cellular respiration.
Explain how soil pollution and soil erosion could be prevented.
Soil pollution can be controlled by the following measures:– By reducing the use of plastics. By controlling the use of chemical fertilisers , pesticides, weedicides & insecticides etc. Soil erosion can be controlled by taking the following steps :- Planting more and more trees will result in the reduction of soil erosion. By stopping deforestation …

List the differences between clayey soil and sandy soil
Clayey Soil Sandy Soil 1. Particles are fine and tiny Particles are bigger among all 2 Particles are tightly packed Particles are loosely packed 3. Holds a better amount of water Water holding capacity is minium 4. It is heavy weight It is light weight 5. Rich in humus and organic nutrients Not rich in …

How is clayey soil useful for crops?
Clayey soil is useful for crops for the following reasons :- It has the best water holding capacity. This soil is rich in organic matter ( humus ) Clayey and loamy soils are suitable for growing cereals like wheat, rice etc. Water holding-capacity of clayey soil supports the growth of crops like paddy which require …
Explain how soil is formed.
.Soil is formed due to the weathering of rocks. Weathering of rock by physical ( air, water, temperature rainfall etc ), chemical and biological decomposition process . In the weathering process, rocks are converted to small pieces, which eventually turn to soil particles to form a layer of soil.
What is soil erosion ?
Soil holds water in it, which is called soil moisture. The capacity of a soil to hold water is important for various crops.
What is Soil erosion?
The removal of land surface by water, wind or ice is known as erosion. Plant roots firmly bind the soil. In the absence of plants, soil becomes loose. So it can be moved by wind and flowing water. Erosion of soil is more severe in areas of little or no surface vegetation, such as desert …
Percolation rate of water in
soil
Calculate the rate of percolation by using the following formula: percolation rate (mL/min) = amount of water (mL) / percolation time (min) For example, suppose that for a certain sample, it took 20 minutes for 200 mL to percolate. So,rate of percolation = 200 mL/ 20 min= 10 mL/min Calculate the rate of percolation in …
The soil is classified on the basis of the proportion of particles of various sizes.
The soil is classified on the basis of the proportion of particles of various sizes. If soil contains greater proportion of big particles it is called sandy soil. If the proportion of fine particles is relatively higher, then it is called clayey soil. If the amount of large and fine particles is about the same, …
