Ecosystem encompassing all the life on earth in the physical environment that supports it

True. 
If this question is a true or false statement then the statement which is mentioned above, “ecosystem is encompassing all the life on earth in the physical environment that supports it” is true and therefore correct. An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
