**Question 30** The structure and maintenance of an ecosystem result from the interactions among the \( \textbf{organisms in that ecosystem} \). Ecosystem properties emerge from the diverse roles, relationships, and functions of all organisms including plants, animals, microbes, and others. **Question 31** Globally, water remains plentiful yet unevenly distributed. While some regions manage sustainable use effectively, others face severe shortages due to overexploitation and pollution. Rapid population growth and climate change further strain future supplies, making integrated water management, innovative technologies, and conservation strategies essential to secure dependable water resources worldwide. **Question 32** Gutters and storm sewers are most concerned with the \( \textbf{surface runoff loop} \). These systems manage rainwater that flows over surfaces, preventing flooding and reducing urban water accumulation.
