Competitors are organisms that use the same resources when those resources are in short supply, leading to a competition for that resource. This is in contrast to mutualists, who have a mutually beneficial interaction, commensalists, who benefit from the interaction without affecting the other organism, and amensalists, who negatively affect another organism without being affected themselves. Predators consume other organisms as their resource, rather than competing for a shared resource.
