Question

What are the 3 ocean ecosystems?

Answer 1

An ecosystem is the basic functional unit of an environment in which living and nonliving organisms interact, both of which are required for the survival of life on Earth. Plants, animals, microorganisms, and all other living creatures, as well as their nonliving surroundings, such as soil, land, air, water, dust, and other natural elements, are all included.
The ecosystem can be as big or as tiny as it wants to be in nature. It is determined by the amount of abiotic components present in the environment.

Complete answer:
The open ocean, deep-sea oceans, and coastal marine ecosystems are among them, each with its own set of physical and biological properties.
An ocean ecosystem's three zones or strata are:
The Aphotic zone
The Disphotic zone
The Euphotic zone
Aquatic ecosystem-
The aquatic ecosystem is a water-based habitat in which organisms interact with the environment's biotic and abiotic components. It is of two types:
Freshwater ecosystem- The freshwater ecosystem accounts for $0.78$ percent of the earth's surface area. Lakes, ponds, rivers, streams, marshes, swamps, and other bodies of fresh water are examples. This area supports a variety of phytoplanktons and zooplanktons. Primary producers include algae and tiny plants, with fish and other freshwater species serving as consumers.
Marine water ecosystem- It is the largest ecosystem on the planet. This environment is likewise based on water, but due to the presence of dissolved salts such as sodium and chlorine, it differs from freshwater. Oceans and the sea are included. It has a large open area that supports a diverse range of flora and fauna.

Note:
Overexploitation of marine resources for food and other valuable items such as corals and pearls is a big hazard to marine ecology. Other threats include pollution and climatic changes, both of which have a significant impact on the ecology.
The essential purpose of any ecosystem is the transfer of energy from one life form to another, which finally circles back and sustains the planet's whole life. There would have been no life on Earth if the ecosystems had not maintained their balance.
