For your better medical test preparation and better Biology MCQs preparation, in this section, we are posting Ecosystem MCQs.
An ecosystem is a biological community of living organisms like plants, animals and microbes in a particular area. The living and physical components of an ecosystem are linked together through nutrient cycles and energy flows. Ecosystems can be of any size, but usually, they are in particular places.
