If Plants Grow Lab Essay

Many living organisms rely on the environment for essential resources, including water, food, and shelter. However, they not only need the help of the environment but also other species that live within the biosphere. This lab aided in demonstrating how the affect of one organism has on another, and whether or not it benefits either organisms or one organism. In order to progress with the experiment we first have to identify our variables that will be used during the experiment. The independent variable is the presence of worms, and depending on how many worms there are will affect the growth of plants. Next, the hypothesis given states, “ If plants grow in soil containing worms, then the plant growth will be greater, because worms help decompose …show more content…
According to data collected, the difference in average heights is a difference of 4 cm in height. The final step is to measure the height of the all plants after a 5-week time frame, and as shown within my data table the difference in average heights is a difference of six cm in height. The results of the lab show that the average height of the experimental group of plants was greater than the average height of the control group who were not given any worms, therefore the data proves the hypothesis to be true. The worms helped the plants grow a greater height because worms help move nutrients toward the roots of plants, such as nitrogen, that are essential for plants to grow. They also create tunnels that allow the soil to absorb more water. So, the worms are not harmed nor benefit; however, the plants earn a great deal of benefit from these worms. This is an example of commensalism, where one organism is benefitted and the other stays the same in a neutral state. As you can see I learned that interdependence of organisms need to occur in order for animals to survive and keep a balance in population size,
