three sentences about the role termites play in modifying the natural proses of water carbon or nitrogen cycle
amm1812

Answer:  

-help to store water in the soil (by increasing infiltration) rather than evaporating (enabling the plants survive long periods of drought)

-mix inorganic and organic compounds in the soil (and thus it can better resist the process of erosion)

-termite’s feces help to prevent erosion  

Explanation:

Decomposers break down complex organic matter into basic compounds containing nitrogen, phosphorus, and calcium, generating water (H2O) and carbon dioxide (CO2) during this process. Termites are critical in an ecosystem because they are decomposers, i.e., they are recyclers that break down organic material into nutrient-rich soil. For example, termites digest the cellulose from dead plants (due to the presence of specific bacteria in their digestive tract), thus allowing the carbon cycle.
