Question

How many types of ecosystems are there?

Answer 1

An ecosystem may be a community of both living and non-living entities of a specific region, that's in constant interaction with one another, maintaining the ecological balance. The biotic or living entities are constituted by humans, plants, and animals while the abiotic or non-living entities are the rock, soil, water, air, and other related components of that region.

Complete answer:
Ecosystems are broadly classified into two types:
Terrestrial Ecosystem: Land-based
Aquatic Ecosystem: Water-based
All ecosystems fall into one of the above-mentioned categories. Listed below are the types of ecosystems:

Forest Ecosystem: The classification is as per the respective climate – boreal, temperate, or tropical. Forest ecosystems in temperate zones may have a flora of coniferous type, deciduous type, or a mixture of both types. Rainforest ecosystems within the tropics have a foremost diverse plant and animal ecosystem than the other region in the world. Here, trees grow tall and foliage is dense and plush with a warm and humid environment, with species right from the basic level up to the cover. The Boreal forests are featured within the far north, with an upscale population of coniferous trees, referred to as the taiga.

Desert Ecosystem: The most defining feature of this ecosystem is that the amount of precipitation it receives, which is that the least as compared to any ecosystem. This ecosystem can exist from the Arctic to the tropics, not all deserts are hot, and some are often windy. Some contain rocks while some have sand dunes. Flora may be a very rare but highly adaptive animal species and insects are found here.

Grassland Ecosystem: These are found in savannas, steppes, and prairies, within the temperate and tropical regions. They will exist in colder regions as well (Siberian Steppe) and share a standard characteristic: semi-aridity. Flowers could also be scattered alongside the grass but trees are almost non-existent. Grasslands are ideal for animal grazing.

Marine Ecosystem: It contains saltwater and inhabits a spread of species. They’re the foremost abundant ecosystems on the earth. Marine enclose not only the oceanic bed but also the tidal zones, salt marshes, estuaries, saltwater swamps, coral reefs, mangroves, etc.

Tundra Ecosystem: Tundra denotes Polar Regions at lower altitudes. It is characterized by harsh environmental conditions almost like deserts and is typically windswept, snow-covered, and treeless. The soil is frozen throughout the year and through the brief summers, snow melts to supply shallow ponds, thus giving rise to small flowers and lichens.

Freshwater Ecosystems: As against marine ecosystems, they pertain to the ecosystem found within the rivers, ponds, lakes, freshwater swamps, springs that have freshwater. They embody planktons, algae, insects, amphibians, and underwater plants.

Note: Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change within the temperature of an ecosystem will often affect what plants will grow there, as an example. Animals that depend upon plants for food and shelter will need to adapt to the changes, move to a different ecosystem, or perish.
