Are dogs hosts or parasites?
Dogs are not parasites because parasites suck the blood of other animals. Dogs are hosts to various parasites, such as ticks and fleas.
How do hosts and parasites interact?
Hosts and parasites interact through a dynamic relationship where parasites depend on hosts for survival, often at the host's expense. Parasites can exploit various resources, such as nutrients or reproductive opportunities, from their hosts, leading to potential harm or disease. This interaction can drive evolutionary adaptations in both parties, with hosts developing defenses against parasites while parasites evolve strategies to overcome these defenses. Overall, the relationship is a complex balance of exploitation and adaptation.
Do most parasites kill their hosts?
No, most parasites do not kill their hosts. They rely on their hosts for survival and typically aim to keep them alive for as long as possible to continue feeding off them.
Do parasites co-evolve with their hosts?
Yes
Do parasites kill hosts?
If they are successful then they don't.
Are animals that harm their hosts and help themselves arachnids?
Of course not; Arachnids are simply 8-legged creatures such as spiders. The only things that I can think of that "harm their hosts to help themselves" are either bacteria or certain parasites.
How are parasites and their host similar to predators and their prey?
Parasites feed off their hosts. Predators feed off their prey. Difference is that parasites want to keep their hosts alive so they can continue to feed off them.
How do parasites help their hosts?
Most parasites don't kill their hosts, because it doesn't take all the nutrients from the host. It only needs a certain amount of nutrients. So it will cause some bad effects on host, but it won't cause complete destruction.
Where do parasites absorb nutrients from?
From their hosts. The hosts may be plants, animals or even micro-organisms.
Parasites that live on the external surface of their hosts?
ectoparasites
How do parasites serve as a density dependent limiting factor?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
