Answer:
Explanation:
When two organisms need to survive but there aren't enough for both of them, it causes competition. For example, there is only 1 worm left on the ground. However, there are two birds. The birds fight against each other to see who will get the last worm.
A predator is an organism that hunts on another organism for food. That organism that is being hunted down is called the prey. A predator depends on the prey to survive.
Commensalism means when there are two organisms, neither one of them is harmed but one gets the benefit. Such as the remora fish and the shark. Symbiosis is when in two species, at least one of them gets the benefit.
A parasite is an organism that lives inside or on a host. A host is the specie in which is getting harmed by the parasite. An example is a tick and a dog. The ticks live on the dog but the dog is not benefiting from it. Instead, it gets harmed from the ticks which makes the ticks the parasite and the dog, the host.
