2.NO, because the plants in deserts do not liberate CO2 as they perform most steps from photosynthesis during night
3.usually, at day times due to transpiration water gets filled in guard cells then they become flaccid and stomata opens and at night water loses from guard cells and cells become thin and pore closes
4.the plant kept in light lives for longer time as plant synthesis their food only in presence on light.
5.Yes , then there is not photosynthesis occurring as photosynthesis involves uses of CO2 and release of O2
6. Fishes has special organs known as gills to breath which uses only dissolved O2 from water to get energy and they don't have lungs to breathe on land
7.Autotrophs:organisms which produces their own food
eg. plants
Heterotrophs:organism depends on other organisms for food.
