Question

effect of temperature on growth of fish
percentage of fish reaching maximum size
water temperature (°c)
key:
brook trout
northern pike
largemouth bass
as global temperatures increases, various fish populations decrease.
support or refute the claim using evidence from the graph.

Explanation:

For fish like Brook trout, as water temp (linked to global warming) rises (e.g., from 10°C to 30°C), the percentage reaching max size drops (from ~100% to near 0), supporting the claim. But Largemouth bass shows an increase at some temps, so the claim isn't universal, but evidence exists to support it for many species.

Answer:

The claim is supported for many fish (e.g., Brook trout, Northern pike): as water temperature (related to global warming) increases, the percentage of these fish reaching maximum size decreases. For example, Brook trout at 10°C has ~100% reaching max size, at 30°C near 0%. (Some species like Largemouth bass show different trends, but overall, evidence supports the claim for multiple fish populations.)
