Scientists have divided the ocean into five main layers. These layers, known as zones, extend from the surface to the most extreme depths where light can no longer penetrate. Consider the map of the ocean's zones, formulate a
hypothesis regarding life forms as you move from the epipelagic to the hadalpelagic zone.
A)
Primary producers change from photosynthetic organisms in the epipelagic
zone to chemosynthesizers in the hadalpelagic zone.
Marine life decreases with depth, both in abundance and biomass, until we
reach the hadalpelagic zone, where no life exists.
B)
C)
As one moves from the epipelagic zone to the hadalpelagic zone. life forms
increase in size to accommodate the huge increases in pressure.
D)
We see much biodiversity in the epipelagic zone, including flowering
plants and vertebrate animals but in the hadalpelagic zone, only bacteria
exist.
