What is the defined relationship between two different species of organisms that are interdependent?

1. Subatomic particle

2. Stimulus

3. Sterility

4. Symbiosis

The correct answer is: Symbiosis

The correct term for the relationship between two different species of organisms that are interdependent is "symbiosis." This concept refers to a close and long-term interaction between two different biological species, which can be beneficial, neutral, or harmful to either or both parties involved. Symbiosis can manifest in various forms, such as mutualism, where both species benefit, commensalism, where one species benefits without affecting the other, and parasitism, where one species benefits at the expense of the other. This relationship is key to many ecosystems, highlighting how different organisms can coexist and support each other in various ways. The other terms do not describe the type of relationship in question. "Subatomic particle" refers to particles smaller than an atom and is irrelevant to biological interactions. "Stimulus" pertains to changes in the environment that provoke a response in an organism, which does not imply a relationship between species. "Sterility" relates to the inability to reproduce and is not a concept of interdependence among different species. Thus, "symbiosis" is the most accurate term for describing interdependent relationships between different species in biology.
