Question

some species of fish move in groups called schools. which two statements best support the claim that schools of fish have an improved survival advantage over an individual fish? a schools of fish are better able to find food sources. b schools of fish produce less waste than individual fish. c schools of fish can swim deeper than an individual fish. d fish are social animals, and a school allows them to meet other fish. e predators are confused by a group and cannot identify a single fish to catch.

Explanation:

• Option A: While finding food sources is good, it doesn't directly relate to survival advantage over individual fish in terms of avoiding being caught.
• Option B: Producing less waste is not a key survival - related advantage over individual fish.
• Option C: Swimming deeper is not a commonly recognized major survival advantage of fish schools over individual fish.
• Option D: If predators are confused by a group (fish school) and can't identify a single fish to catch, it directly gives the fish in the school a survival advantage over an individual fish which would be easier for a predator to target.

Answer:

D. Predators are confused by a group and cannot identify a single fish to catch.
