Plants provide a great deal of benefits to both humans and the environments and ecosystems in which they exist. These benefits include generating oxygen, providing energy, developing as habitats for certain types of animals, preserving the qualities of different types of soil and providing a number of useful products. In addition to the food and oxygen provided, plants are used to help manufacture many different types of products.
According to the Missouri Botanical Garden, plants are able to convert light energy into food. This makes them indispensable for a number of ecosystems around the world. Without plants, the food chain would not have one of its most fundamental and necessary links. Energy in food form, even meat, ultimately comes from the sun and plants by extension.
In addition to creating food, plants also make oxygen. This is a by product of the food development stage, but it is also incredibly important to sustaining life on the planet.
Plants do more than just provide these two necessary functions, however. Many organisms find shelter and habitats in certain types of plants. For examples, trees are often home to a variety of different birds, bugs and small mammals. In this way, plants can provide safety and protection to other organisms. Plants can also be broken down into useful resources, like wood, which can be used to construct buildings.
