Final answer:
Interactions in an ecosystem can lead to interdependence, where organisms rely on each other for resources with competition being an example where two species vie for the same resources. Commensalism exemplifies an interaction where one species benefits and the other is unaffected.
Step-by-step explanation:
Some interactions lead to interdependence, which occurs when organisms in an environment rely on each other for resources. An example of this concept is competition, which occurs when two species require the same limited resource, such as food, water, shelter, or sunlight. Another example is commensalism, which occurs when one species benefits from the interaction and the other species is neither harmed nor helped.
Competition is a biological interaction where organisms vie for the same types of resources in their habitat. This can be between members of the same species (—intraspecific competition—) or between members of different species (—interspecific competition—). In this context, competition can lead to a decrease in the availability of resources, limiting the growth and survival of the competing populations.
Interdependence highlights the mutual reliance between organisms within an ecological community. It is essential to understand that this interdependence stems from the organisms' needs for various resources, which drives the dynamic interactions such as competition, symbiosis, predation, and commensalism among species.
