Freshwater leeches are segmented worms that latch onto fish or other animals and suck their blood. The fish are harmed, but are not killed. The leeches drink blood until they are full, and then they let go.
The symbiotic relationship described in the scenario is parasitism. In this relationship, the leeches benefit by obtaining nourishment from the blood of the fish or other animals, while the fish are harmed by losing blood and potentially suffering negative effects from the leech's feeding activity.
The symbiotic relationship described here is called parasitism. In parasitism, one organism (the parasite) benefits at the expense of another organism (the host). In this case, the leech is the parasite, as it feeds on the blood of the fish (the host) to obtain nutrients, potentially harming the fish in the process.
The symbiotic relationship described here is called parasitism. Parasitism is a type of symbiosis in which one organism, known as the parasite, benefits at the expense of another organism, known as the host. In this case, the leeches act as parasites by attaching themselves to the fish or other animals, feeding on their blood, and causing harm to the host. The fish, on the other hand, are negatively impacted as they experience harm or discomfort, but they are not typically killed by the leeches.
