Leaves absorb sunlight and air to make food for the plant. Flowers produce seeds for reproduction. Seeds have an embryo and food supply. Some plants reproduce without seeds. Fruits develop from the flower of a plant and contain seeds.
Vegetables are the root, stem or leaf of a plant.
Plants are affected by environmental conditions. An ecosystem is made of all the living things in an area and the physical matter with which they interact. Ecosystems include producers, consumers and decomposers. Decomposition is one of nature's recycling methods. The earth's surface is mostly water in the form of oceans, seas, lakes, rivers, ponds, streams and glaciers.
