उत्तर १
Limitations of ecological pyramids:
- It never takes into account the same species belonging to two or more trophic levels.
- It assumes a simple food chain, which never exists in nature.
उत्तर २
- Exclusion of Decomposers: Decomposers, which are essential for nutrient recycling, are often omitted from ecological pyramids. An inaccurate depiction of energy flow may result from excluding decomposers.
- Over-Simplification: Because they depict only linear linkages, ecological pyramids often oversimplify food webs. In actuality, organisms may interact in more complex ways and belong to numerous trophic levels, which are not represented by a straightforward pyramid structure.
