Final answer:
A symbiotic relationship is a coevolved relationship where both species benefit, and there are three main types: mutualism, commensalism, and parasitism.
Step-by-step explanation:
A symbiotic relationship is a coevolved relationship where both species benefit. It is a close and long-term interaction between two different species living in close physical association. There are three main types of symbiotic relationships:
- Mutualism: Both species benefit from the relationship. For example, the relationship between bees and flowers, where the bees get nectar and the flowers get pollinated.
- Commensalism: One species benefits while the other is neither benefited nor harmed. An example is a barnacle attaching itself to a whale, which provides the barnacle with transportation while the whale is unaffected.
- Parasitism: One species benefits while the other is harmed. This is seen in relationships between ticks and mammals, where the ticks feed on blood and harm the host.
