Question

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.

Answer 1

C) As one moves from the epipelagic zone to the hadalpelagic zone, life forms increase in size to accommodate the huge increases in pressure.

Step-by-step explanation:

A) is wrong because life does exists in the hadalpelagic zone, in fact life exists in all layers.

B) don't see any options.

D) This is incorrect since invertebrates such as starfish and tube worms may live at this depths, contrary to popular belief.

The bathypelagic zone follows. It's also known as the midnight zone or the black zone. This zone ranges from 1,000 to 4,000 meters (13,124 feet). The animals' own light is the only apparent light here. At this depth, the water pressure reaches 5,850 psi. Despite the stress, there are surprisingly many animals here. Sperm whales may dive to this depth for feeding. Due to the absence of light, most creatures in these depths are black or red.
