Ribosomes consist of two major components: the small ribosomal subunits, which read the RNA, and the large subunits, which join amino acids to form a polypeptide chain.
Answer: false, for example, if a frog eats flies, and the flies are land animals, if they go extinct the frogs could die off, meaning any fish or water dwellers that eat the frogs can starve and cause a large chain reaction.
Hope this helps ^^
