Prologue: The prologue chapter introduces biology and it’s meaning. It states the difference between pseudoscience and testable science. For example, evil forces do not kill the living contents in the biosphere nor do the gods help keep it alive. Instead, the biosphere is based on scientific explanations from observations, inferences, and experiments. In these experiments, there are testable hypotheses, such as whether your plant will die or why the plant grew to the top of the bottle. Biology is directly linked with technology when using the scientific method in an experiment. For the biosphere, we used microscopes to sample the water. This was done to see if there is life in the pond culture. With further experimentation, this helps us

These two factors make up an ecosystem. Multiple ecosystems make up a biosphere. In my biosphere, the abiotic factors are the soil, sunlight, and water. The biotic factors are all the living organisms. The producers are the plants. There is no main consumer since I don’t have an animal in my biosphere. The decomposers are the mold. The laws of thermodynamics are also introduced and explained in this chapter. The first law states that energy is neither created or destroyed, but can change form. For example, energy can turn into heat. In my biosphere, when energy is transferred from the plant to the mold (this is when the mold was eating the leaves of the plant), the energy turns into heat and is unusable. The second law states that systems change in a way that leads to disorder or entropy. If the biosphere ends up dying, it is completely out of order from when it was first …show more content…
Since life began before human civilization, there is no sure answer, but through experimentation, scientists have come up with a theory. Chemical evolution is explained by Miller’s apparatus which includes energy sources like lightning. In this chapter, a definition in the BSCS Biology Blue textbook states, “living systems must be able to reproduce, must be subject to mutations that can be passed on to offspring, and must be subject to natural selection.” (p. 458). There is no way to see the origin of life form in the biosphere since there are already complex life forms (plants) in there, but parts of the definition stated above are present. For example, natural selection takes place in the biosphere. The world is based on survival. In the biosphere, if the environment does not fit what the organisms need (e.g. amount of water and sunlight), they will all die. If an organism survives, then it is the most fit for that
