Explanation:

Understanding Pathogens and Parasites

Pathogens and parasites are related but represent different categories when it comes to organisms that can cause disease. A pathogen is any microorganism, such as bacteria, viruses, fungi, or protozoa, that can cause disease. For example, the bacterium Escherichia coli can be pathogenic in certain strains and lead to severe gastrointestinal illness.

On the other hand, a parasite is an organism that lives on or in a host organism and derives nutrients at the host's expense. Examples include tapeworms or the malaria-causing protozoan Plasmodium. While all parasites can be considered pathogens since they can cause disease, not all pathogens are parasites since many are free-living and do not require a host to exist. Therefore, the statement that "pathogens and parasites are unrelated to one another" is False.
