Question

Which ecosystem has the maximum biomass?

• A. Grassland ecosystem
• B. Pond ecosystem
• C. Lake ecosystem
• D. Forest ecosystem

Answer 1

The correct option is D Forest ecosystem

Biomass is the mass of living biological organisms in a given area or ecosystem at a given time. Pond and lake ecosystem occupy very little area when compared to forest and grassland ecosystem. And hence the biomass in lake and pond ecosystem will be less. When compared to the forest, grassland has only a few trees or shrubs and characterized by mixed herbaceous (non-woody ) vegetation cover and is dominated by grasses or grass-like plants. The biomass is maximum in a forest ecosystem because of their size and longevity of trees. Forest ecosystem has formed the most massive and complex ecosystems of the earth. Even though the animal biomass of the forest is small, the total amount of plant biomass per hectare is high.
