Sunlight :)
Go with D !! Sunlight gives energy for all !! plants male food from it and convert in organic components !! Them consumer take it directly or indirectly !!
They replace the lost ions by active uptake through active transport
of ions from the surrounding waters. This is exhibited in freshwater fishes that
actively take in these ions through the gills. Most of the ions involved in osmoregulation in freshwater are those of Na+ and Cl-.
When the ratio of O2 to CO2 within their leaves INCREASES, C3 plants undergo a shift toward more PHOTORESPIRATION and less CALVIN CYCLE.
In C3 plants increase in the concentration of O2 leads to photorespiration. Increase in the amount of CO2 decreases decreases the rate of photorespiration.
Chemical reaction good luck on your test! :)
