Explanation

The correct answer is 'Option 1'. Key Points The correct order of the sentence is "RQPS." Here's why: R. "occur naturally when temperature, water, and" - This part sets the stage for the conditions under which algal blooms occur, making it the logical starting point after the given start of the sentence "Some algal blooms." Q. "nutrient conditions are optimal, and they can be" - This part logically follows R, finishing the list of conditions and introducing the idea that these blooms can be beneficial. P. "beneficial to aquatic life, since these tiny" - This part continues the idea introduced by Q, explaining how these blooms are beneficial, which is because these tiny organisms... S. "organisms form the base of the food chain" - This part logically finishes the sentence by explaining why the tiny organisms mentioned in P are beneficial. Therefore, the correct order is RQPS. i.e."Some algal blooms occur naturally when temperature, water, and nutrient conditions are optimal, and they can be beneficial to aquatic life, since these tiny organisms form the base of the food chain."
