IAE3 Identify which species would remain if the acidity of the lake water increased until it had a pH of 5.0?mayfliescrayfishbasssalamanderstroutfrogsperch

To answer this question, we need to know the pH tolerance levels of each species mentioned. The pH scale ranges from 0 to 14, with 7 being neutral. Below 7 is acidic and above 7 is basic. A pH of 5.0 is considered acidic.

1. Mayflies: Mayflies are sensitive to pH changes and prefer a pH range of 6.0 - 8.0. They would not survive in a pH of 5.0.
2. Crayfish: Crayfish can tolerate a wide range of pH levels, from 5.5 to 9.0. They would survive in a pH of 5.0.
3. Bass: Bass fish prefer a pH range of 6.5 - 9.0. They would not survive in a pH of 5.0.
4. Salamanders: Salamanders prefer a pH range of 6.0 - 8.0. They would not survive in a pH of 5.0.
5. Trout: Trout fish prefer a pH range of 6.5 - 9.0. They would not survive in a pH of 5.0.
6. Frogs: Frogs can tolerate a wide range of pH levels, from 4.0 to 8.0. They would survive in a pH of 5.0.
7. Perch: Perch fish prefer a pH range of 6.0 - 9.0. They would not survive in a pH of 5.0.

So, if the acidity of the lake water increased until it had a pH of 5.0, the species that would remain are crayfish and frogs.
