can live off host, but usually needs host for nourishment
periodic parasite
The statement “can live off host, but usually needs host for nourishment” is generally true for many organisms that are parasitic in nature. A parasite is an organism that lives on or inside another organism (the host) and benefits at the host’s expense.
Some parasites can live for a limited time without a host, either because they are in a dormant stage or because they have some mechanism for survival such as spores or eggs. However, most parasites require a living host to complete their lifecycle and reproduce.
Parasites rely on their hosts for nourishment because they often lack the ability to produce their own food. They extract nutrients from the host organism, which can cause harm to the host. The harm caused by parasites can range from mild irritation or discomfort to severe illness or death, depending on the type of parasite and the host’s immune response.
In summary, while some parasites can survive for a limited time without a host, they typically require a host for nourishment and survival.
