Question

If in atmosphere concentration of co2 is 200 ppm then

Answer 1

Answer:

Rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.

Answer 2

When measuring gases such as oxygen, or carbon dioxide (Co2), or methane, the term concentration is used to describe the gas amount by volume in the air. The common unit of measurement is parts-per-million (ppm)

Explanation:

• Indoor CO2 levels usually differ between 400 and 2,000 ppm. Outdoor CO2 levels are usually 350-450 ppm. Power plants, trucks, and cars  all tend to increase the levels of outdoor Co2 in populated areas.
• 200 ppm of Co2 indicates low concentration of Co2 in the atmosphere. In general, Co2 concentrations were as low as 180-200 ppm 13,000-30,000 years ago and 140,000-160,000 years ago during the coldest parts of the last 2 ice ages
• High levels of CO2 in the atmosphere — mostly induced by people who continue to use fossil fuels and chop forests as carbon sinks — disrupt the natural cooling process of earth, trap heat on the surface and trigger global warming
• The current ppm of Co2 (as of 2019) is around 414. At the prsent rate of increase in Co2, levels will hit 500 ppm in about 50 years, leading to increase in  temperature of than 3 degrees Celsius that would cause rise in sea level endangering global food supplies, extreme bouts of weather, destroy the Amazon rainforest through fire and drought, and cause disruptive mass migrations,
