Question

Create a procedure(at least 5 steps) using bio-indicators that you could do to determine the health of a body of water or an ecosystem.

Answer 1

Answer:

⭐Worms

⭐Changes in the functioning of the nervous systems of worms are used to measure levels of soil pollution. The numbers of earthworms in the soil can also be used to indicate the health of the soil.

⭐One example of a bioindicator is lichens. These plants, which live on surfaces such as trees or rocks or soil, are very sensitive to toxins in the air. This is because they obtain their nutrients mostly from the air. We can tell our forests have clean air by the amount and types of lichens on the trees. Different species of lichen have different levels of susceptibility to air pollution, so we can also get an idea of the level of pollution by observing which species are present.
