Fill in the chart with the words- symbiosi, commensalis, mutualism, and parasitism- in the appropriate place
It is helpful to first know what the words mean prior to determining their location.
Symbiosis is when two organisms' lives affect one another in some way. This can be beneficial to both or beneficial to only one of the two organisms.
Commensalism is a form of symbiosis in which one organism benefits and the other is neither harmed nor benefited. A classic example of commensalism is the barnacles on whales. The barnacles hitch a free ride and the whales are unaffected.
Mutualism sounds like mutually. Just as mutually means that both parties are in agreement, mutualism is a form of symbiosis in which both parties benefit. For example, oxpeckers are birds that eat the ticks off of zebras. The bird gets a free meal and the zebra is freed of the ticks.
Lastly, parasitism is a symbiotic relationship in which one organism benefits and the other is harmed. Ticks are parasites of many mammals.
Therefore, in your diagram symbiosis goes on top while mutualism, commensalism, and parasitism all go below because mutualism, commensalism, and parasitism are types of symbiosis. In other words, symbiosis is a category of behavior and the other three (mutualism, commensalism, and parasitism) are all types of this behavior, each type of symbiotic behavior having a different outcome for the participants: neutral, beneficial or harmful.
