Which of the following best describes a difference between a mutualistic relationship and a parasitic relationship?

Answer no 1:

The correct option is B) Parasitism benefits only one organism, while mutualism benefits both organisms.

Explanation:

A symbiotic relationship can be described as a type of interaction among different organisms living in an area. Some organisms might benefit from this relationship, others might not be affected while some might be harmed.

A symbiotic relationship in which one organisms gains benefit while the other gets harmed is called parasitism. For example, ticks that live on a cat.

A symbiotic relationship in which both organisms benefit from each other is termed as mutualism.

Answer No 2:

The correct option is A) It is given off as heat.

Explanation:

Not all of the energy is transferred from one trophic level to another when an organism consumes another organism from the trophic level below it. Scientists have calculated that only 10% of the energy gets transferred from the lower trophic level to the upper trophic level. Studies have shown that most of the energy is lost in the environment as heat and hence, only 10% of the energy gets transferred.
