I think you forgot to give the options along with the question. I am answering the question based on my knowledge and research. <span>The lowest level of environmental complexity that includes both living and non living factors is the ecosystem. I hope that this is the answer that has come to your desired help.</span>
An ecosystem is a huge association of breathing organisms such as animals, plants, and microorganisms in a particular region. The living and physical elements are joined together through nutrient series and energy progress. Energy enters the ecosystem through photosynthesis and is consolidated into the plant network. By supporting plants and on one-another, creatures play an essential role in the evolution of matter and energy through the system. They also impact the number of plants and microbial biomass present. By decomposing down dead fundamental matter, decomposes and deliver carbon back to the environment and promote nutrient cycling by transforming nutrients stored in stagnant biomass.
