10. Study of toxic effects of chemicals on biological systems.
11. Gradual accumulation of substances (e.g., toxins) in organisms.
12. Increase in concentration of pollutants along the food chain.
13. Measurable biological changes indicating exposure, effect, or susceptibility (e.g., enzyme activity).

15. Species used to detect environmental hazards before human effects appear.
16. Non-living environmental components such as temperature, soil, water, and chemicals.

1. Use of living organisms or biological responses to assess environmental quality or exposure to pollutants.
2. The variety of species, genes, and ecosystems in a given area.
3. A community of living organisms interacting with the physical environment.
4. A species or biological parameter that reflects environmental conditions (e.g., lichens for air quality).
6. Measurable parameters that reflect the state of the environment are known as ... indicators.
7. Initial reference data used for comparison in long-term monitoring is called ... monitoring
9. Effects of human activities on the environment.
