For heterotrophic organisms, competition is least caused by the inadequacy of light. Heterotrophic organisms are living beings that obtain their food by consuming other organisms, either directly or indirectly. Examples include animals, fungi, and some bacteria. Since heterotrophs require organic compounds for their survival, the availability of nutrients and space are usually the main limiting factors for their growth and reproduction. Competition arises when multiple individuals or populations compete for limited resources. In the case of heterotrophic organisms, competition can be intense for resources such as nutrients and space, as these are necessary for their survival and reproduction. However, light is not a major resource for heterotrophs since they do not produce their own food through photosynthesis. Therefore, the inadequacy of light is least likely to cause competition among heterotrophic organisms.
