Study Notes

Ocean Zones

The ocean is divided into five vertical layers based on light penetration.
The Epipelagic Zone, also known as the sunlight zone, extends from the surface to 200m and has about 90% of all marine life.
The Mesopelagic Zone, also known as the twilight zone, extends from 200m to 1,000m and has only 1% of light penetrating.
The Bathypelagic Zone, also known as the midnight zone, extends from 1,000m to 4,000m and is dark with no sunlight.
The Abyssopelagic Zone, also known as the abyssal zone, extends from 4,000m to 6,000m and has a freezing temperature and high pressure.
The Hadopelagic Zone, also known as the hadal zone, extends from 6,000m to 11,000m and is the deepest part of the ocean.

Intertidal Zone

The Intertidal Zone is the area closest to the shore, covered with water at high tide and exposed to air at low tide.
Species in this zone must adapt to changing conditions and moving water.

Neritic Zone

The Neritic Zone lies over the continental shelf and has shallow water.
It is rich in nutrients and sunlight, making it ideal for marine producers.

Rainforest Layers

Tropical rainforests have five layers: emergent, canopy, understory, understrowth, and forest floor.
The Emergent Layer has scattered tall trees that can withstand heavy winds and harsh sunlight.
The Canopy Layer has a dense network of branches and leaves that block most sunlight, wind, and rain.
The Understory Layer has shorter trees and branches at varying heights, and is dark and humid.
The Undergrowth Layer has large, bright flowers to attract pollinators.

Adaptations

Deep-sea creatures have adapted to the dark environment by becoming bioluminescent or transparent and without eyes.
Some deep-sea creatures have adopted chemosynthesis to make their own food in the absence of sunlight.
Some rainforest plants have large, bright flowers to attract pollinators.
Some animals have lightweight seeds that can be carried by strong winds to help them propagate.
