Answer 1

Answer:

The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.An ecosystem is the basic unit of the field of the scientific study of nature. According to this discipline, an ecosystem is a physically defined environment, made up of two inseparable components:

The biotope (abiotic): a particular physical environment with specific physical characteristics such as the climate, temperature, humidity, concentration of nutrients or pH.

The biocenosis (biotic): a set of living organisms such as animals, plants or micro-organisms, that are in constant interaction and are, therefore, in a situation of interdependence.Together with freshwater ecosystems, marine ecosystems are also part of the broader category of aquatic ecosystems. Marine ecosystems cover more than 70% of the Earth’s surface and have a high salt content. Some examples of marine ecosystems are offshore systems like the ocean surface, the deep sea, pelagic oceans or the seafloor. But there are also nearshore systems like coral reefs, mangroves or seagrass meadows.

Marine ecosystems can too be characterized following the abiotic and biotic dimensions mentioned above. In this way, its biotic components are organisms and their species, predators, parasites, and competitors. On the contrary, the concentration of nutrients, the temperature, sunlight, turbulence, salinity and density are its abiotic components.
