Competition between organisms typically results in harm to both species involved. This is because competition occurs when two or more species vie for the same limited resources, such as food, water, territory, or mates. When these resources are scarce, the struggle to acquire them can lead to reduced survival and reproductive success for both competitors. Even if one species is slightly more successful in securing the resource, the other species still suffers due to a lack of access. This dynamic reflects the inherent costs of competition, as energy and time are diverted towards competing rather than growing, reproducing, or engaging in other beneficial activities. Such outcomes can lead to decreased population sizes, reduced individual health, and overall lower fitness for both species involved in the competition. In contrast, the other options suggest scenarios where competition results in mutual benefit, one species gaining an advantage, or neutral effects, which do not accurately capture the typical consequences of competitive interactions in ecology.
