Plants come from the kingdom plantae and are eukaryotic, multicellular organisms. While plants are the basis of the food web and the primary producers in terrestrial ecosystems, they themselves, or at least most of them are able to make their own food. In the aerobic environments that plants live in, they carry out a process called photosynthesis, using the oxygen to make food. Through photosynthesis – light energy + 6CO2 + 6H2O -> C6H12O6 + 6O2, plants are able to absorb energy from the sun and convert it into chemical energy for food. This is what makes plants autotrophic. Even though the sun enables plants to make their own food, however, they are merely suppliers.

The sun supplies plants with energy to make food, not to make food for them because that’s what happens through photosynthesis that they carry out on their own. At school, students are enrolled by their parents who paid to have them educated. Sitting through a series of classes, over a duration of usually twelve years, students are expected to graduate and move on to college. While many of them have grown and matured over those twelve years, most important is that their knowledge too has broadened. In a class, teachers are paid to teach students from textbooks or from their own insight. They don’t guarantee that students graduate after taking their class; they do, however, teach students everything they’ll need to know so that they can wisely apply their knowledge whether to other classes, to their daily lives, or even later on in college.
