Define the term "symbiosis."

• A. A type of extreme competition between species
• B. A relationship between two different organisms living closely together
• C. The process of natural selection
• D. A method of communication among species

Answer: (B)

The term "symbiosis" specifically refers to a relationship between two different organisms that live closely together, which can take various forms, including mutualism, commensalism, and parasitism. In this context, mutualism benefits both organisms, commensalism benefits one while having little to no effect on the other, and parasitism benefits one at the expense of the other. This close association often results in a significant impact on the survival and reproduction of the interacting species. Understanding symbiosis is crucial in ecology as it highlights the interconnectedness of living organisms and how different species can coexist and influence each other's lives in their ecosystems. This concept is fundamental to grasping the dynamics of biodiversity and ecosystem health.
