Which one is the incorrect regarding parasitism ?

Options

A. parasite show special adaptation
B. ectoparasite show more complex life cycle
C. endoparasite show more complex life cycle
D. koel is the example of brood parasite

Answer

**Step-by-Step Solution:**

1. **Understanding Parasitism**: Parasitism is a biological interaction where one organism (the parasite) benefits at the expense of another organism (the host). This relationship is characterized by one species being harmed (the host) while the other benefits (the parasite).

2. **Identifying Types of Parasites**:
- **Ectoparasites**: These are parasites that live on the external surface of the host, such as fleas or ticks.
- **Endoparasites**: These parasites live inside the host's body, such as tapeworms or the malaria-causing Plasmodium.

3. **Analyzing the Statements**:
- **Statement 1**: Parasites show spatial adaptation. This is true as many parasites have evolved adaptations that allow them to survive and thrive in their host environments.
- **Statement 2**: Ectoparasites show more complex life cycles. This is incorrect. Ectoparasites generally have simpler life cycles compared to endoparasites, which often have more complex life cycles due to their need to navigate different host environments.
- **Statement 3**: Endoparasites show more complex life cycles. This is true as endoparasites often require multiple hosts or stages to complete their life cycles.
- **Statement 4**: Koel is an example of brood parasitism. This is true as the Koel lays its eggs in the nests of other birds, relying on them to raise its young.

4. **Conclusion**: The incorrect statement regarding parasitism is that "Ectoparasites show more complex life cycles." This statement is false as endoparasites typically exhibit more complex life cycles.

**Final Answer**: The incorrect statement regarding parasitism is that "Ectoparasites show more complex life cycles."
