How can changes in abiotic factors impact a community? Give one specific example.

Changes in abiotic factors, such as a decrease in moisture levels, can lead to reduced plant growth, which in turn affects herbivores that rely on those plants for food. This can disrupt the entire food chain within the community.

This answer is effective as it explains the cause-and-effect relationship between abiotic factors and community dynamics, illustrating the interconnectedness of ecosystem components. The question assesses the student's understanding of the implications of abiotic changes.
