In the given question, a structure of a complex food web has been provided in which the organism present at the different trophic level are affected by different factors including-

Please help!What are the roles of a decomposer? Check all that apply.
9966 [12]

Answer:

decomposer decomposes :) so it breaks down the organic matter into simpler compounds. it's very important process because complex compounds that build living organisms are not absorbable for other organisms, thus chemical cycling wouldn't be possible and the whole ecosystem would shut down. dead plants and animals would be everywhere and new organisms couldn't be born/grown. mold breaks down dead organic matter like dead trees. as the result simple compounds come into existence and can be assimilated by plants
