Fungi are heterotrophic organisms, meaning they cannot produce their own food through photosynthesis like plants do. Instead, they obtain their nutrition by absorbing organic matter from their environment. Unlike plants that contain chlorophyll pigments for photosynthesis, fungi lack chlorophyll and rely on external sources of nutrition.

Characteristic Features of Fungi
Fungi are a diverse group of organisms with unique characteristics that distinguish them from plants and animals. Among the options provided, heterotrophic nutrition is a key feature.
Heterotrophic Nutrition
- Fungi cannot produce their own food like plants do.
- They obtain nutrients by absorbing organic matter from their environment.
- This process involves the secretion of enzymes that break down complex substances into simpler compounds, which are then absorbed through their cell walls.
Comparison with Other Options
- Chlorophyll Pigments:
- Fungi do not possess chlorophyll and therefore cannot perform photosynthesis.
- Cellulose Cell Walls:
- While plants have cellulose in their cell walls, fungi have a cell wall made of chitin, which is different from cellulose.
- Autotrophic Nutrition:
- Fungi are not autotrophic; they rely on organic matter for nutrients, as opposed to autotrophs, which create their own food through photosynthesis or chemosynthesis.
Conclusion
Given these points, the correct answer to the characteristic feature of fungi is indeed "heterotrophic nutrition." This feature underscores their role as decomposers in ecosystems, highlighting their importance in nutrient cycling and organic matter breakdown.
