1. Plants look green because of the presence of a substance called chlorophyll. This chlorophyll absorbs all except green colour of the visible spectrum. And only this green colour reaches our eyes.
2. The respiratory system of earthworm is its skin called cuticle called cutaneous respiration because they are lower level organism and they don't have complex structures.
3. Nutrition is necessary for an organism to run its continuous process Viz metabolism. Cells gets killed by its own organelle called lysosomes which eats its cell when they lack food.
