In insects, “incomplete metamorphosis” is when young animals are similar to adults and change gradually into the adult form, and “complete metamorphosis” is when there is a profound change between larval and adult forms.
Once ingested, sediment particles stay inside the animal about 3 hours to ensure complete nitrogen-fixation.
