Which of the following organism have parasitic mode of nutrition?a)Pen...
In parasitic nutrition organism derives its food from the body of another living organism called host without killing it. Parasitic mode of nutrition is observed in several fungi, bacteria, few plants like Cuscuta and some animals like Plasmodium and round worms. Plasmodium causes malarial disease.

Understanding Parasitic Nutrition
Parasitic nutrition is a mode of nutrition where an organism derives its nutrients from another living organism, known as the host, often harming it in the process. Among the options provided, the organism that exhibits this mode of nutrition is Plasmodium.
Overview of the Organisms
- Penicillium:
- This is a genus of fungi known for its role in the production of antibiotics and food spoilage. It is saprophytic, meaning it feeds on decaying organic matter.
- Plasmodium:
- This is the correct answer. Plasmodium is a genus of protozoan parasites that causes malaria in humans. It lives and reproduces within the host's red blood cells, drawing nutrients and ultimately leading to the host's illness.
- Paramecium:
- A ciliated protozoan that primarily feeds on bacteria and small organic particles through a process called phagocytosis. It is not parasitic.
- Parrot:
- Parrots are birds that primarily feed on fruits, seeds, and nuts. They have a mutualistic relationship with some plants but do not exhibit parasitic behavior.
Conclusion
In summary, among the listed organisms, Plasmodium is the only one that exemplifies a parasitic mode of nutrition. It specifically targets the host’s blood cells, leading to severe health issues, which is characteristic of parasitism. Understanding these distinctions is vital in the study of ecology and the relationships between organisms.
