Ecosystems can be classified based on various factors. The ecosystem can be classified based on formation, based on region, and based on their size.
Classification of ecosystems based on formation:
Ecosystems are classified as natural and artificial ecosystems based on how they are formed.
1. Natural ecosystems: Ecosystems like ponds, lakes, rivers, forests, etc., evolve naturally without the involvement of human beings. Such ecosystems are called natural ecosystems.
Lake
2. Artificial ecosystems: Ecosystems like zoos, gardens, parks, agricultural fields, aquariums, etc., are man-made ecosystems. Such ecosystems are called artificial ecosystems. These ecosystems are developed and maintained by humans.

Forests, grasslands, deserts, mountain and tundra ecosystems.

2. Aquatic ecosystem: Ecosystems that exist in water are known as aquatic ecosystems.
Example:
Freshwater ecosystems - ponds, lakes, rivers; marine water ecosystems - oceans and seas; and estuarine ecosystems.
Aquatic ecosystem
Classification of ecosystems based on their size:
Ecosystems can also be classified based on their size:
1. Micro ecosystem: Small scale ecosystems such as a pond, tree trunk, etc.
Pond
2. Meso ecosystem: Medium-scale ecosystems such as lakes, coral reefs, forests and sand dunes.
Coral reef
3. Macro ecosystem: Large scale ecosystem or an entire rainforest, also called a biome.
