Bioindicators

4. The most sensitive lichens are shrubby and leafy
5. Mosses and this organism are good indicators of environmental health due to their ability to store toxins.
6. A major property of bioindicators is the ability to give a measurable response that reflects the whole population or this.
10. These bioindicators, including mosses, are particularly useful in determining air pollution by accumulating heavy metals.
12. These simple, slow-growing plants are sensitive to air pollution and commonly found on rocks or tree trunks.
14. These small aquatic animals are used to measure pollution in water ecosystems, reflecting environmental health.
16. An organism used to monitor the health of an environment.
18. The disappearance of lichens in forests is often a sign of this type of environmental stressor.
19. This type of bioindicator helps in understanding the quality of an aquatic ecosystem through the accumulation of pollutants.
20. Bioindicators like plants or animals are often used in this process to gather real-time analytical information.

1. Bioindicators must be abundant, have wide distribution, and show a response to environmental contamination, fitting this selection criterion.
2. This organism is used to test for water pollution by measuring changes in its cellular metabolism that affect light emission.
3. An ecosystem's overall health can be indicated by the presence or absence of this plant, often found in aquatic environments.
7. The most tolerant lichen in appearance.
8. This term refers to microorganisms used to monitor aquatic health by testing for toxins.
9. What major environmental factor are lichens sensitive to in forests?
11. These water-dwelling organisms are often used as indicators of water pollution.
13. This microscopic organism, commonly found in fresh waters, is used in toxicity tests involving sewage solutions.
15. These species are useful bioindicators of environmental pollution and can reflect air quality changes.
17. This type of microorganism can produce stress proteins when exposed to toxins like cadmium or benzene.
