Answer:
Because earthworms do not like soil that is too acid, alkaline, dry, wet, hot or cold, their presence is a good indicator of soil conditions suitable for plant growth. Earthworms do not like acid soils with pH (CaCl2) less than 4.5. The addition of lime raises pH and also adds calcium.
Specifically, we tested for the presence of lipids, proteins, polysaccharides, and monosaccharides in samples of potato, oil, milk, sugar, egg, rice, tofu, bread, and glucose. It is important to know about the presence of different types of macromolecules in our food because it is important. Google
<span>An ecosystem consists of a population of organisms and its
physical environment, and a population is made up of many different
communities of organisms. Every one of the creatures of similar species
living together that live in a particular biological system are known

Relevant: It measures an important part of an objective or output;
<span>Objective: </span>If two people measure the same indicator using the same tool, they should get the same result. The indicator should be based on fact, rather than feelings or impressions (another way to say this is to say that it should be Measurable);
Available: Indicators should be based on data that is readily available, or on data that can be collected with reasonable extra effort as part of the implementation of the (sub-) project.
Realistic: It should not be too difficult or too expensive to collect the information (related to the next one in the list);
Specific: The measured changes should be attributable to the project, and they should be expressed in precise terms
