the human liver fluke’s life cycle (D) is an example of parasitism, where one species benefits at the expense of another. The other options describe mutualistic or commensal relationships.

Understanding Parasitism
Parasitism is a type of symbiotic relationship where one organism (the parasite) benefits at the expense of another organism (the host). In this interaction, the parasite derives nutrients and energy from the host, which may suffer harm as a result.
Why Option D is Correct
The human liver fluke (Fasciola hepatica) is a well-known example of a parasitic organism. Here’s a detailed explanation of why option D represents parasitism:
Why Other Options are Not Parasitism
In summary, option D is the only choice that clearly illustrates the characteristics of a parasitic relationship, making it the correct answer.
Parasitism is a type of symbiotic relationship where one organism (the parasite) benefits at the expense of another organism (the host). In this interaction, the parasite derives nutrients and energy from the host, which may suffer harm as a result.
Why Option D is Correct
The human liver fluke (Fasciola hepatica) is a well-known example of a parasitic organism. Here’s a detailed explanation of why option D represents parasitism:
- Life Cycle Involving Intermediate Hosts: The liver fluke has a complex life cycle that includes two intermediate hosts: typically a snail and a fish. The fluke's eggs hatch in water, and larvae infect the snail. The snail becomes a host where the fluke can develop further.
- Host Dependency: The fluke relies on these hosts to complete its life cycle, as it cannot reproduce or develop without them. This dependency exemplifies the parasitic nature of its existence.
- Harm to the Host: The liver fluke can cause significant harm to its definitive host, which is often livestock or humans, leading to liver damage and various health issues. This negative impact on the host is a hallmark of parasitism.
Why Other Options are Not Parasitism
- Option A: The interaction between sea anemones and clownfish is a mutualistic relationship, where both organisms benefit.
- Option B: The Monarch butterfly's chemical defenses are an evolutionary adaptation for survival, not indicative of parasitism.
- Option C: Lichens are symbiotic relationships between fungi and algae or cyanobacteria, which do not involve parasitism.
In summary, option D is the only choice that clearly illustrates the characteristics of a parasitic relationship, making it the correct answer.
