A marine biologist dredges up a small animal from the bottom of the ocean. It is uniformly segmented, with short, stiff appendag
es and soft, flexible skin. It has a complete digestive system and a closed circulatory system, plus multiple true coeloms. Based on this, you determine that the animal must be a(n) a. mollusc
b. annelid
c. lancelet
d. crustacean
e. roundworm
Annelids in the phylum of animals which includes about 22000 extant species. The animals of this group possess segmented body and thus are called ringed worms.
Each segment of the body contains the same organs and are usually found in the aquatic environment in the hydrothermal vents and the tidal zones. Some species are found in the terrestrial environment.
Since the biologist found the animal from the deep ocean with a segmented body and soft skin therefore, the animal belongs to the annelids.
<h3>The micro-organisms which convert the dead plants and animals to humus are known as decomposers.</h3><h3> Examples: Fungi and Bacteria. Decomposers recycle and convert the dead matter into humus which mixes with forest soil and provides necessary nutrients to plants.</h3>
<span>This is in how you look at it. as a food source, fish are producers since we as humans eat fish, but they are also consumers since others eat other fish as food. </span>
