Paragraph 1: A symbiotic relationship is an interaction between two or more
species in which one species lives in or on another species. There are three
main types of symbiotic relationships: parasitism, commensalism, and mutualism.
The first and the third can be key factors in the structure of a biological
community; that is, all the populations of organisms living together and
potentially interacting in a particular area.
1. Which of the following statements about commensalism can be inferred from
paragraph 1?
○It excludes interactions between more than two species.
○It makes it less likely for species within a community to survive.
○Its significance to the organization of biological communities is small.
○Its role in the structure of biological populations is a disruptive one.
怎麼排除選項1呢？在1和4之間猶豫好久
最後一題挑重點題
1. Parasitic relationships involve the interplay of aggression by the
parasite and resistance and adaptation by the host.
2. Mutualism ordinarily involves an interaction between two members of the
same species.
3. Mutualism is unique among symbiotic relationships in that it r benefits
both partners involved in the relationship.
4. Parasitic damage to Australian rabbits was never reversed because the
rabbits were unable to adapt to the parasites' attacks.
5. The rarity of commensal relationships stems from the difficulty of finding
relationships that benefit one species without affecting the other.
6. The structure of biological communities depends on the types of relationships
that exist among the species within.
