Parastitic angiosperms are

Options

A. tertiary consumers
B. primary consumers
C. secondary consumers
D. decomposers

Answer

**Step-by-Step Solution:**

1. **Understanding Parasitic Angiosperms**: Parasitic angiosperms are flowering plants that depend on other plants for their nutrition. They derive nutrients by attaching themselves to host plants.

2. **Identifying Their Role in the Ecosystem**: In an ecosystem, organisms are categorized based on their role in the food chain. The main categories are producers, consumers, and decomposers. Producers are typically plants that create their own food through photosynthesis.

3. **Defining Consumers**: Consumers are organisms that cannot produce their own food and must obtain it by consuming other organisms. They are further classified into primary consumers (herbivores that eat producers), secondary consumers (carnivores that eat primary consumers), and tertiary consumers (carnivores that eat secondary consumers).

4. **Classifying Parasitic Angiosperms**: Since parasitic angiosperms derive their nutrition from other plants (which are producers), they fit into the category of consumers. More specifically, they are primary consumers because they feed directly on producers.

5. **Conclusion**: Therefore, parasitic angiosperms are classified as primary consumers in the ecosystem.

**Final Answer**: Parasitic angiosperms are primary consumers.
