Explanation:

the uptake of CO2 through photosynthetic pathways is exactly matched to the respiratory release of carbon dioxide, and the uptake of O2 by respiration is exactly matched to the photosynthetic release of oxygen is called as compensation point.The grasshoppers belong to an animal class known as Arthropoda. The blood of grasshoppers is known to be greenish or yellowish in colour. The circulatory medium of blood in grasshoppers does not contain red blood cells, which normally make the blood to be red in colour.Plants absorb water through their entire surface – roots, stems and leaves. However, the majority of water is absorbed by root hairs. Root hairs are thin-walled uni-cellular outgrowths of epidermis
