The best answer would be a predator, but it could also be considered a host.
The size of the host population can control the spread and prevalence of diseases. In a larger host population, there may be more individuals for a disease to spread to, potentially leading to faster transmission. Conversely, in a smaller host population, diseases may not spread as easily and could be contained more easily.
No. The dog is a host. Prey is killed by a predator. A host is fed upon by a parasite.
yes
Trophic transmission occurs when the encysted larval form of a parasite are transmitted to the final host during the consumption of the intermediate host. They then mature in the final host. In simple terms - the young of the parasite live in the gut of a prey animal. That prey animal is then consumed by a predator. If it is the correct predator (trophically transmitted parasites can be species-specific) then the parasite will mature and reproduce in the gut of the predator.
A leech does not have predator and prey relationships, so it does not kill its prey. A leech is a parasite. It simply attaches itself to a host.
Parasites benefit from being with the host all the while harming the host. The host is nice and tolerant that it allows the parasite from it without it benefiting from the parasite at all.
Parasitism involves one organism (parasite) living off of another (host) in a harmful manner but without killing the host. Predation involves one organism (predator) killing another (prey) for food.
No, the dog would be considered the prey. A flea is a parasite, which makes it the predator.
A predator kills an animal for food. A parasite feeds off of it's host, but does not kill it because if it's host dies it needs to find another source of food. They are similair because they both are nourished from their prey (or host).
NOT prey or predator
