The author tries to persuade the reader to agree with his claim about the importance of ecosystems by providing facts.
The author does not present statistics. However, the author does highlight that ecosystems "enrich the soil" and create the air. Also the "life sustaining matrix" is built of microorganisms that evolved along humanity. The author does not used deductive reasoning because he is not building his argument by saying that "if this then this". Finally, rather than restating his claim he aims to explain why ecosystems are important.
