It is crucial that we protect, conserve, and support the global population of producers. This claim is supported by the evidence that was discovered in the experiment of the water tank. As seen in the experiment, when the fish were increase, the levels of oxygen were decreased. Then, as soon as more plants (producers) were added to the tank, the oxygen levels increased once again. Theses evidences can be applied on a larger scale of the earth. An analogy could be made between the fish and plants in the tank to the animals, humans, and plants all over the world. As the population of animals and humans continue to grow around the world, more and more trees and plants get cut down. As this continues the oxygen levels will decrease, which can be supported by the evidence in the lab.
