Question

“Increase in the amount of carbondioxide leads to increase in global temperature” – write a
short note on the above statement

Answer 1

Answer:

carbon dioxide is a green house gas . it increases the temperature of earth . it captures the heat from the ray of sun this keeping the earth warm at night . but in the increase of it the temperature of the earth rises . it is mainly caused by the burning of fossil fuel as petroleum which is bitterly known as liquid gold,coal and etc.the factories that leaves harmful chemical gases are an another main cause for global warming . for this there may be acid rain in the nature also.

The main purpose of irrigation is to supply plants with adequate water for transpiration and for incorporating the element hydrogen in plant tissues through photosynthesis and subsequent biosynthesis of various tissues and organs. Transpirational flux requires several hundred times more water than photosynthesis.

The main purpose of irrigation is to supply plants with adequate water for transpiration and for incorporating the element hydrogen in plant tissues through photosynthesis and subsequent biosynthesis of various tissues and organs. Transpirational flux requires several hundred times more water than photosynthesis.In a series of U.S. Department of Agriculture studies beginning in 1910 in Akron, Colorado, Briggs and Shantz (1913a,b; 1914) showed that the water requirement of plants is linearly related to the biomass production of plants. They established this linear relationship by growing plants in metal containers filled with soil. Throughout the period of growth, they monitored water use carefully by weighing and adding measured amounts of water to maintain a desirable soil water content as water lost by plant transpiration was replenished.
