While biodiversity is indispensable to the survival of life on Earth, Conclusion biodiversity does not require the survival of every currently existing species. For there to be life on Earth, various ecological niches must be filled; Support many niches, however, can be filled by more than one species.
The survival of every currently existing species isn’t necessary for biodiversity, because the ecological roles that must be occupied for there to be life on Earth can be satisfied by multiple species.
The conclusion rejects that the survival of every current species is necessary for biodiversity: “biodiversity does not require the survival of every currently existing species.”
Which one of the following statements most accurately expresses the conclusion drawn in the argument?
Biodiversity does not require that all existing species continue to exist.
This rephrases the conclusion: The author believes that the survival of every current species is not necessary for biodiversity:
There are various ecological niches that must be filled if there is to be life on Earth.
This is context. It provides background that is important for understanding the premise, which is that many of these niches can be filled by more than one species.
The survival of life on Earth depends upon biodiversity.
This is context. While important for understanding the overall argument, it is not the conclusion.
There are many ecological niches that can be filled by more than one species.
This is a premise. It provides support for why biodiversity does not require every currently existing species to survive.
The species most indispensable for biodiversity fill more than one ecological niche.
This is not an idea that is discussed in the stimulus.
