This is a very broad question, but I will try to remember the basics. All ecosystems must have a producer. A producer is a plant that can make its own energy (autotrophic). Then, primary consumers eat the producer, taking 10% of the energy produced in the previous organism for itself. This is a small ecosystem, but an ecosystem nonetheless.
