Three types of symbiotic relationships are mutualism, commensalism and parasitism. In symbiosis, at least one member of the pair benefits from the relationship, while the host may also benefit, may be unaffected or may be harmed.Know More
Within a mutualistic relationship, both organisms benefit from the symbiotic pairing. The relationship between zebras and oxpecker birds is mutualistic. The oxpecker removes ticks and other parasitic organisms from the zebra's skin. The oxpecker is provided with food, while the zebra is provided with a form of pest control.
Commensalism is a symbiotic relationship where one organism consumes the unused food of another, but does no harm to its host. An example of commensalism is the remora fish and a shark. The remora fish forms a temporary attachment to the shark and picks up food scraps when the shark feeds. The shark is not harmed but also receives no benefit from the relationship.
During parasitism, the parasitic organism lives on or within its host to secure nourishment. In a parasitic relationship, some harm is done to the host organism. Animal parasites include viruses, bacteria, tapeworms, fleas, lice and mites.Learn more about Biology
The three types of natural selection are directional selection, disruptive selection and stabilizing selection. Natural selection is when organisms adapt to the environment and pass down these adaptations to their offspring when they breed. Those that are not able to adapt die before breeding, putting an end to unfavorable traits.Full Answer >
The three major types of symbiosis are mutualism, where both species benefit, commensalism, where one species benefits and the other is unaffected, and parasitism, where one species benefits and the other is harmed. Symbiotic relationships can occur within an organism's body or outside of it.Full Answer >
Fungi, bacteria and viruses form the three categories of microorganisms. These microorganisms, or microbes, live in all areas of the world and perform diverse duties. Some help living organisms while others act as pathogens; they come in uni-cellular or multi-cellular forms, but their small sizes make microorganisms only visible to humans through microscopic lenses.Full Answer >
According to Spark Notes, eubacteria comprise an ancient group and can be saprophytes, photoautotrophs or symbionts. Eubacteria are also known as the true bacteria. They are able to reproduce by binary fission, with a split approximately every 20 minutes.Full Answer >
