Symbiotic Relationships

• Symbiotic relationships involves organisms living in close nutritional relationship
• Mutualism is where both organisms benefit from each other.
• Commensalism is when one organism benefits while the other is neither benefited nor harmed.
• Parasitism is when one organism benefits, while the other is harmed.
• The two types of parasitism are Endoparasites and Ectoparasites.
• Endoparasite lives inside another organism's body.
• Ectoparasite lives on the surface of another organism's body.
• Examples of endoparasites include tapeworms, roundworms, flukes, protozoa, bacteria, viruses, fungi, etc.
• Examples of ectoparasites include ticks, fleas, lice, mites, leeches, crabs, etc.
• Competition is where organisms compete for the same reason.
• Two types of competition are Intraspecific competition and interspecific competition.
• Intraspecific competition refers to the competition of individuals of the same species.
• Interspecific competition refers to the competition individuals who have different species.
• The prey is the animal being hunted by the predator.
• Predation refers to one organism that kills and eat another organism to obtain nutrients.
• The predator eats and kills the prey.
• Example of a commensalism is a tree and an epiphyte.
• Example of a mutualism is a plant and a bee. The plant provides nectar and pollen for the bee to feed on.
• Example of a competition are fishes competing with one another for food.
• Symbiosis refers to two or more organisms that are called symbionts, living together over a long period of time.
