Which of the following best defines an ecosystem?
A system formed by the interaction of biotic and abiotic components
An ecosystem is a functional unit of nature in which living organisms interact with one another and with the non-living environment around them.
The living organisms, such as plants, animals and microorganisms, form the biotic components, while factors like air, water, soil, sunlight and temperature form the abiotic components.
Options that mention only plants, only animal habitats or a collection without physical factors are incomplete, since none of them captures the interaction between living and non-living parts that defines an ecosystem.
Hence, the correct answer is A system formed by the interaction of biotic and abiotic components.
