  3. 6. Large, complex molecules made up of amino acids that are essential for the structure, function, and regulation of the body's tissues and organs.
  4. 7. Pertaining to algae, a diverse group of photosynthetic organisms found in various aquatic environments.
  5. 9. Natural materials or substances such as minerals, forests, water, and fertile land that can be used by humans to produce goods and services.
  6. 13. The variety and variability of life forms within a given ecosystem, biome, or the entire planet, encompassing species diversity, genetic diversity, and ecosystem diversity.
  7. 15. The ability to maintain or preserve resources and ecological balance by avoiding depletion and ensuring long-term environmental health and stability.
  8. 17. The molecule that carries genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.

  1. 1. The enrichment of water bodies with nutrients (especially nitrogen and phosphorus), often leading to excessive growth of algae and depletion of oxygen, which can harm aquatic life.
  2. 3. The process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose, using carbon dioxide and water.
  3. 5. Refers to a species that is native to and restricted to a specific geographic area.
  4. 8. Gases in the Earth's atmosphere that trap heat, contributing to the greenhouse effect and global warming. Key examples include carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O).
  5. 10. Communities of living organisms interacting with each other and their physical environment, forming a complex and interdependent system.
  6. 11. chemical or natural substances added to soil or land to increase its fertility and promote plant growth.
  7. 12. A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. Members of a species are reproductively isolated from other such groups.
  8. 14. The air, water, and land in or on which people, animals, and plants live
  9. 16. The amount of crop produced on a given amount of land, typically measured per unit area.
  10. 19. The excessive hunting of wildlife to the point where the population of a species is significantly reduced or brought to the brink of extinction.
