This weird thing-a-ma-bobber is called the Circle of Life (just kidding), this is actually a model of the different levels of biotic factors. The first stage is an organism. It is the single individual of a population. A population is the second level. A population is all the individuals of the population in the same area and time. The third level is a community. A community is different populations living together in one place and time. The fourth stage is an ecosystem. An ecosystem is how the community interacts with one another and with abiotic factors in the ecosystem. The last level is the biosphere. The biosphere is all of the ecosystems in the world. It's basically saying the biosphere is the Earth.
