This document discusses nutrition in plants. It explains that plants get nutrients from the soil and light energy from the sun to produce their own food through photosynthesis. There are different modes of nutrition in plants - autotrophs can produce their own food, heterotrophs obtain food from other organisms, and some plants have parasitic or symbiotic relationships. The document also describes two activities - one showing that sunlight is necessary for photosynthesis, and another observing the fungus bread mould growing on bread as an example of a saprotroph.
