In the northeastern pacific ocean, sea otters occur at a relatively low abundance. by preying upon sea urchins, sea otters maintain underwater kelp (large algae) "forests", which would otherwise be decimated by the herbivorous sea urchins. the kelp forests supply food for a wide variety of marine organisms, as well as providing refuge from predation and nursery habitat for juveniles. based on this, what type of species best describes sea otters?

Wich organism obtains its energy from dead or decaying matter

Monomers are the building blocks of larger molecules, called polymers. for example, proteins are composed of chains of amino acids that are linked together. cellulose is a polymer that makes up plant cell walls. cellulose is made from a chain of c6h10o5 molecules. which monomers are most likely used to produce cellulose? why?

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
