Many animals within the park rely on specific types of plants as their sole food source. Monarch butterflies, for example, only lay their eggs on milkweed, and only eat milkweed while in their caterpillar phase. Milkweed requires a moderately acidic soil to grow, surviving in soil pH levels from 4.8 to 6.8.As with most other plants, it cannot tolerate pH levels below 4. Overly-acidic soil prevents roots from being able to absorb water and nutrients crucial for survival.ilkweed requires a moderately acidic soil to grow, surviving in soil pH levels from 4.8 to 6.8.

The acidity of yogurt can range from surprisingly acidic to relatively neutral. While some mild yogurts have a pH as high as 5.5, which is only slightly acidic, others have a low pH of about 3.0, which is extremely acidic compared to most other foods. Ordinary yogurts generally have a pH of about 4.0 to 4.5. Aside from cultures and environment, several other factors can affect the product's acidity. Alkaline ingredients such as banana and blueberry may raise yogurt's pH, while acidic ingredients such as orange and sugar may lower it.
