The birds in this experiment live on the island and survival is not easy and it is baking hot during the day‚ freezing cold at night and there isn’t much food available. Because of this‚ the birds have very specialized

centre of a shrub this are due to light levels. Explanation: Plants have stomata to obtain carbon dioxide from the atmosphere and remove oxygen produced in photosynthesis. During photosynthesis the chloroplasts in the leaf cells synthesize as a result of exposure to light‚ while oxygen is produced as a by-product. As the outer leafs are exposed to higher light levels the stomatal density has to be high and because the inner leaves are exposed to lower light levels they will so have a lower stomatal density
