In order to follow the scientific method, your description should start with anobservation and be followed by (i) a testable hypothesis, (ii) an outline of the experiment that will test thehypothesis, (iii) a description of the type of data that will be collected, and (iv) a possible conclusion that couldlikely be made after completing the experiment and analyzing the data.A group of researchers wanted to determine how leaf herbivory and seed production of a legume plant (legumes are a family of plants which includes beans and lentils) were affected by the presence of its mutualistic rhizobia (a group of nitrogen-fixing bacteria). They designed an experiment with two treatments: (1) rhizobia absent and herbivores present and (2) rhizobia present and herbivores present. Provide two additional treatments and briefly explain how they would contribute to our understanding of the results of this experiment.
