Marine Biology
What is a marine biologist?
Someone who studies the organisms of the ocean!
The clam and squid are both in the ______ phylum
mollusk
the term that describes oxygen levels that are too low to sustain life
hypoxia
_____ percent of the energy is transferred from one trophic level to the next in a food web
10 percent
An example of a filter feeder is
clam, mussel, scallop, oyster
What percent of the Earth is covered in water?
71%
the five kingdoms of life are
animal, plant, fungi, bacteria (eubacteria archaebacteria), protist
the two main nutrients responsible for algae blooms are
nitrogen and phosphorous
It is better to eat (higher/lower) on the food chain
lower
plankton describes
organisms that "float" in ocean
How much of the ocean is unexplored?
95%
The class of the squid is ________ the class of the clam is __________
cephalopod, bivalve
the main reason eutrophication occurs
runoff
The term to describe the accumulation of toxins as you move up the food web
bioaccumulation
organisms that spend their life on the ocean floor
Benthic
The area between high and low tide
intertidal zone
a microalgae that photosynthesizes
phytoplankton
the three main types of macro algae are
Red, Green, and Brown (seaweed)
The equation for photosynthesis is
6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
The famous oceanographer that is trying to save the oceans by educating our world of "hope spots"
sylvia earle
The five oceans are
a microalgae that doesn't photosynthesize
zooplankton
What happens after an algae bloom occurs
Algae dies, sinks to benthic zone, is eaten by oxygen consuming bacteria, deplete ecosystem of oxygen (hypoxia), fish and other organisms die
The equation for cellular respiration is
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
Give them space to reproduce and grow without being exposed to human interference
