If the soil pH in a habitat changes significantly, how might this affect the plant species present in that community?

A significant change in soil pH can affect nutrient availability and the ability of plants to absorb minerals. Some plant species may thrive in certain pH levels while others may struggle, potentially leading to a shift in the dominant plant species in the community.

This answer is strong as it addresses the specific effects of soil pH on plant health and community composition. The question assesses the student's ability to connect abiotic factors with biotic responses in an ecosystem.
