Ocean Zones
What zone receives enough sunlight for photosynthesis?
What is the Euphotic Zone?
Which color of light travels deepest in ocean water?
What is Blue light?
What tiny organism forms the base of the ocean food web?
What is Phytoplankton?
What is it called when an organism produces its own light?
What is Bioluminescence?
About how deep can sunlight reach in clear ocean water?
What is about 200 meters?
What zone has very little light but is not completely dark?
What is the Twilight Zone (Mesopelagic Zone)?
Which color of light is absorbed first in ocean water?
What is Red light?
What deep-sea fish uses a glowing lure to attract prey?
What is an Anglerfish?
What adaptation helps fish blend with light above and darkness below?
What is Countershading?
What major factor affects how deep light can travel in water?
What is Water clarity (turbidity)?
What zone has no sunlight at all?
What is the Aphotic Zone?
Why does blue light penetrate deeper than red light?
What is because water absorbs red wavelengths faster?
Why are most photosynthetic organisms found near the surface?
What is because they need sunlight to make food?
Why do many deep-sea animals appear black or dark red?
What is to blend into the darkness?
What process allows phytoplankton to convert sunlight into energy?
What is Photosynthesis?
Which zone ranges from about 200–1,000 meters deep?
What is the Twilight (Mesopelagic) Zone?
What happens to light intensity as depth increases?
What is It decreases exponentially?
What is the main role of phytoplankton in marine ecosystems?
What is Primary producers / base of food web?
What is counterillumination?
What is producing light on the underside to match light from above?
Why is the euphotic zone important to global climate?
What is because it drives carbon cycling through photosynthesis?
Why is the euphotic zone shallower in coastal waters than in open ocean?
What is because sediment and particles block sunlight?
How does turbidity affect ocean ecosystems?
What is It reduces light penetration and limits photosynthesis?
Why do many twilight zone organisms migrate vertically at night?
What is to feed near the surface while avoiding predators?
Name two purposes of bioluminescence.
What is predator avoidance and attracting prey?
How could climate change impact ocean light zones?
What is by changing water clarity and affecting phytoplankton productivity?
