Which of the given options arranges the following sentences in the most logical sequence to form a meaningful paragraph? 1. Without keystone species, entire ecosystems can collapse, leading to significant biodiversity loss. 2. The concept of a keystone species was first introduced by ecologist Robert Paine, who studied the effect of removing certain predators from an ecosystem. 3. Keystone species play a disproportionately large role in maintaining the structure and stability of their ecosystems. 4. For example, sea otters help regulate sea urchin populations, preventing the destruction of kelp forests. 5. This idea revolutionized ecology by highlighting how some species have a far greater impact on their environment than others.
3-2-5-4-1
Sentence 3 defines keystone species and introduces the topic, so it opens the paragraph.
Sentence 2 follows with the origin of “the concept” — introduced by ecologist Robert Paine.
Sentence 5 begins “This idea revolutionized ecology”, and “This idea” refers back to the concept in sentence 2, so 5 comes after 2.
Sentence 4 (“For example, sea otters…”) gives an example of a species with a far greater impact, illustrating sentence 5.
Sentence 1 states the consequence of losing keystone species — ecosystem collapse — and works as the conclusion.
Hence, the logical sequence is 3-2-5-4-1.
