Question

Which ecosystem has the maximum biomass?
A. Lake ecosystem
B. Forest ecosystem
C. Grassland ecosystem
D. Pond ecosystem

Answer 1

Hint: The water forms the major part of our Earth but the most ecosystem biomass resides on the lands. The animals and plants are usually found to be grown on the land rather than in water. Deserts and polar regions have the least ecosystem due to extreme conditions.

Complete answer:
Ecosystem is the biological interaction of all the organisms and their physical environment. It forms the geographical area where plants and animals habitat and interact with each other.
Biomass is the usage of plants or animals for obtaining energy. So every area has its ecosystem with biomass.

> Option A: Lake ecosystem: it has only the aquatic plants and animals which can grow in the lakes. It will have limited biomass.
> Option B: Forest ecosystem: being a very large area of forest, it can support a huge life and ecosystem of different species of plants and animals. It covers up to 70% of the total ecosystem.
> Option C: Grassland ecosystem: it is smaller than forests so have less biomass than the forest.
> Option D: Pond ecosystem: Ponds are smaller aquatic bodies so can support a small biosystem.

Hence, the correct answer is option (B).

Note: Forests form the complex web of organisms. It covers most of life on Earth. Forests are of different forms which depend on their location, their altitude, longitude, latitude, soil, temperature etc. Forests cover up to 4 billion hectares of land on Earth. More than 300 million people live in the forest areas. They have access to all the necessities.
