Explanation:

• Question 4:
• A species is defined as a group of individuals that can interbreed and produce fertile offspring. A population is a group of the same species in a specific area. Ecology is the study of the relationships between organisms and their environment. A community is made up of different populations interacting in an area.
• Question 5:
• Globally, the largest use of fresh water by humans is for agricultural irrigation. Washing and home use, drinking and cooking, and electrical production use less fresh water compared to agriculture.
• Question 6:
• A population consists only of biotic (living) factors as it is a group of the same species. A habitat includes both biotic and abiotic (non - living) factors. An ecosystem has biotic and abiotic components interacting. The biosphere is the global sum of all ecosystems, which also has both biotic and abiotic aspects.

Answer:

• 4. A. species
• 5. D. agricultural irrigation
• 6. C. population
