Studied by 44 peoplepelagic zone
open water portion of the ocean
benthic zone
bottom of the ocean
neritic zone
area from low tide to the edge of the continental shelf
abyssopelagic zone
the deepest water in the open ocean
supralittoral zone
shore bottom that is splashed but not submerged in the benthic zone
nekton
marine organisms that swim
plankton
marine organisms that drift with the current, unable to swim against the currents of the ocean
benthos
marine organisms that live on or in the ocean floor
Epifauna and Epiflora
the organisms (fauna) and plants (flora) that live on top of the ocean floor
infauna
organisms that live in the mud and clay of the ocean floor

Life requires energy to...
to accomplish work.
cellular respiration
the conversion of carbohydrate into useable energy
primary producers
create their own energy rich molecules used for life
Chemosynthesis
performed in the absence of light.
Products of Photosynthesis
Carbohydrate (primary), Oxygen
Primary production in the ocean comes from...
phytoplankton
Common elements found in life
H, C, N, O
Primary way that hydrogen and oxygen enter lifeforms
through water consumption
Rubisco
enzyme responsible for converting carbon dioxide allowing carbon to be fixed to other molecules
Life organizes matter into...
cells and energy
This system is light independent in photosynthesis
Calvin cycle
Coral bleaching occurs when
The coral animal expels algae living inside them because the calvin cycle is hindered by warm waters.
Rubisco is used during
the calvin cycle
Primary producers create saccharides
true
It takes more energy to create matter in a lifeform than that matter gives back.
True
Scientists classify marine environments
based on a series of physical factors.
Entropy states that life retains energy as it ages.
False
Autotroph
An organism that makes its own food
Heterotroph
An organism that cannot make its own food. Consumer
Cellular respiration
releases energy from energy rich compounds.
Production can fluctuate due to season, light availability, and based on geography.
True
Organisms exist in a low entropy state.
True
Calvin cycle
where the carbohydrates are created.
Photosystem I
NADPH
Photosystem II
ATP and frees up 2 electrons for photosystem I
Calvin cycle
makes 'sugar'
Effect of high temps on photosynthesis.
Hinders the Calvin cycle.
Effect of Paraquat on photosynthesis
Increased ATP production, but Photosystem I and the Calvin Cycle were hindered.
Effect of Diuron on photosynthesis
stops all electron transport by taking free electrons up immediately
