Question

6.5) what are the similarities and differences between predation and parasitism? 6.6) define symbiosis. 6.7) how is symbiosis similar to commensalism and mutualism?

Explanation:

6.5) Both predation and parasitism are relationships where one organism benefits at the expense of another. In predation, the predator kills and consumes the prey immediately. In parasitism, the parasite lives on or in the host and usually does not kill it quickly, often relying on it for a long - term source of nutrients.
6.6) Symbiosis is a close and long - term biological interaction between two different biological organisms.
6.7) Commensalism and mutualism are both types of symbiotic relationships. In commensalism, one organism benefits while the other is neither helped nor harmed. In mutualism, both organisms benefit. All three involve close associations between different species.

Answer:

6.5) Similarity: One organism benefits at another's expense. Difference: Predator kills prey immediately; parasite lives on/in host long - term without usually killing quickly.
6.6) A close and long - term biological interaction between different organisms.
6.7) Commensalism and mutualism are types of symbiotic relationships, all involving close species associations.
