Answer
The correct answer is (B).Here's why:* **Parasitism** is a symbiotic relationship where one organism (the parasite) benefits at the expense of another organism (the host). The parasite typically lives on or in the host and derives nutrients from it, often causing harm to the host.* **(A) A bee pollinating a flower:** This is an example of *mutualism*, where both organisms benefit. The bee gets food (nectar and pollen), and the flower gets pollinated.* **(B) A tick feeding on a dog's blood:** This is a classic example of *parasitism*. The tick (parasite) benefits by getting food, while the dog (host) is harmed by the loss of blood and potential transmission of diseases.* **(C) Two male deer fighting for territory:** This is an example of *competition*, where two organisms compete for the same resources.* **(D) A lion hunting a zebra:** This is an example of *predation*, where one organism (predator) kills and consumes another organism (prey).
