In green plantsthe carbon dioxide is taken from the air through their leaves. The minerals they need aretaken up through their roots, as is water which is also essential for life.Animals take in food through their mouths or, in very small organisms, they may beabsorbed through their skin.The challenge for plants is to evolve ways to transport their nutrients from the surface ofthe plant to cells in the middle of the plant that also need to be nourished. Animals alsomust have systems for moving the food they take in to their stomachs or through theirskin (for small organisms) to the rest of their bodies. They must also have ways totransport waste products out of their bodies.Very small organisms use a method called diffusion to move materials. Nutrients that aredissolved or suspended in water are absorbed through their skins.
