Question

symbiosis
trends of symbiosis
what trends do you observe about symbiotic relationships?
as you have seen though these examples of symbiosis, whether it be mutualism, parasitism, or commensalism, youll notice how organisms can use others in their environment to increase their chances of survival.
over time, organisms will adapt structures, features, and behaviors to better utilize their relationship and increase their chance of survival and reproduction.
which of the following is true about symbiosis?

• species in symbiotic relationships must both be benefitted
• species in a symbiotic relationship harm each other
• species in a symbiotic relationship must develop new traits to best allow the relationship to occur
• species in a symbiotic relationship can adapt new traits that help them survive using their partner
• changes in a species traits occur rapidly after a symbiotic relationship is established

Explanation:

1. Analyze the first option: Symbiotic relationships include parasitism (where one is harmed, one benefits) and commensalism (one benefits, one is unaffected), so not both need to be benefited. Eliminate this.
2. Analyze the second option: Mutualism is a symbiotic relationship where both benefit, so they don't always harm each other. Eliminate this.
3. Analyze the third option: The text says organisms "will adapt" structures/features/behaviors, not that they "must develop new traits" (adaptation can also be of existing traits or behaviors, not necessarily new traits). Eliminate this.
4. Analyze the fourth option: The text states "Over time, organisms will adapt structures, features, and behaviors to better utilize their relationship and increase their chance of survival and reproduction" which matches this option (adapt new traits to survive using their partner).
5. Analyze the fifth option: The text implies adaptation over time, not rapid changes. Eliminate this.

Answer:

The correct option is: Species in a symbiotic relationship can adapt new traits that help them survive using their partner
