Final answer:

Opportunistic pathogens can cause disease in hosts with weak defenses. The immune system plays a key role in defending against pathogens. Interactions between agent, host, and environment influence disease transmission and prevention.


Explanation:

Definition:

In biology, an opportunistic pathogen is a microorganism that can cause disease in individuals with compromised host defenses. Pathogens vary in their ability to cause disease, with highly virulent ones being more likely to infect a host.

Hosts and Pathogens:

A host is the organism that is susceptible to the effects of a pathogen. Pathogens include bacteria, protists, fungi, and other infectious agents that can harm the host. The complex immune system responds to pathogens by identifying, combating, and remembering them for future protection.

Transmission and Defense:

Pathogens exploit various pathways to move from one host to another, often causing symptoms of disease along the way. Understanding the interactions between agent, host, and environment is crucial in preventing disease epidemics and maintaining overall health.
