Aquatic Science - Unit 6 : Lesson 4 - 6 + Quiz 2
Terrestrial means ____.
"of or pertaining to land"
How is a niche different from a habitat?
A niche encompasses a species' physical home, the environmental factors the species needs to survive, and all interactions with other species in the same ecosystem. The niche of a specie cannot change, the habitat is constantly changing depending on the interactions with other species.
Interaction Species A Species B Mutualism Benefits __________
Benefits
Interaction Species A Species B Predation ____________ Harmed
Benefits
Lesson 4
Biotic Relationships
Which sugar is formed as a result of photosynthesis?
C6 H12 O6
Which sugar is formed during photosynthesis?
C6H12O6
How does burning fossil fuels affect the carbon cycle?
Carbon dioxide is released in an amount greater than what can be used by plants for photosynthesis or is able to be absorbed by the ocean. Excess carbon dioxide causes the carbon cycle to function improperly and probably cause global warming. When burning fossil fuels additional carbon dioxide is released into the atmosphere.
What happens if there is too much nitrogen in an aquatic system?
Excess nitrogen can cause an explosion of growth in algae, as well as diatoms and other plankton. As a result of competition caused by the excess algae, a decline in population of other organisms can also cause the decline and death of many other aquatic species. Excess algae growth and it competes with the other organisms for nutrients.
Interaction Species A Species B Competition Harmed ___________
Harmed
Interaction Species A Species B Parasitism Benefits __________
Harmed
Why is nitrogen important to all living things?
It is a part of amino acids, which help build proteins. It is involved in the majority of the energy processes that occur in the cells of organisms. It is a part of nucleic acids, which help build DNA.

How is the nitrogen cycle like the carbon one?
Just like the carbon cycle, the nitrogen cycle is the process where nitrogen is cycled out of the atmosphere and converted into forms that are usable by earth's organisms.
Why is phosphorus important to living things?
Phosphorous is in ATP and in cell membranes. Phosphorous is in DNA and RNA. Phosphorous is in bones, including your teeth.
Where does the oil in cars come from?
Phytoplankton convert the sugar created through photosynthesis into oil. The phytoplankton that is dead become liquefied over time due to pressure, and oil deposits are formed.
Quiz 2
Quiz 2
Select some ways humans impact the nitrogen and phosphorous cycles.
Sewage leaks cause an excess of these elements in the cycles. Fertilizers cause an excess of these elements in the cycles.
Lesson 6
The Nitrogen and Phosphorous Cycles
What is true about parasitism and predation?
They both are relationships in which one species benefits by harming another species. Predation usually does not result in death for the host.
Terrestrial means "of or pertaining to land."
True
Whenever anything is burned, carbon monoxide is released into the atmosphere.
True
Interaction Species A Species B Commensalism Benefits __________
Unaffected
What is parasitism?
a relationship in which a species lives in or on another species and feeds off that species
What is competition?
a relationship in which different species attempt to use the same limited resource
What is commensalism?
a relationship in which one species benefits from another species without harming or helping that species
What is predation?
a relationship in which one species feeds on another species
What is mutualism?
a relationship in which two different species benefit each other
What is symbiosis?
a relationship in which two unlike species live in close association with each other.
Nitrogen is found in ___.
amino acids DNA fertilizers
What are nitrogen fixing bacteria?
bacteria that can convert, or "fix," the atmospheric nitrogen into usable forms
Why is carbon the element of life?
because it is found in all living things
How can too much carbon dioxide lead to global warming?
carbon dioxide traps heat and may lead to overheating of the earth
The relationship between remoras and sharks is an example of ____.
commensalism
What types of organisms are nitrogen-fixing bacteria in an aquatic ecosystem?
cyanobacteria
Humans contribute to excess nitrogen and phosphorus in aquatic ecosystems through the use of ____________.
fertilizers
In parasitism, a parasite lives in or on a ___________.
host
What is the carbon cycle?
how carbon in the atmosphere is converted into usable forms for living organisms and then returned to the atmosphere
What is the nitrogen cycle?
how nitrogen is cycled out of the atmosphere and changed into usable forms
What types of plants are nitrogen-fixing bacteria in terrestrial ecosystems?
legume plants peanuts and soy beans
The relationship between anemones and clown fish is an example of ____.
mutualism
Symbiosis is most similar to which relationships?
mutualism commensalism
The relationship between a tick and a human is an example of ____.
parasitism
Bones, including teeth, contain ___.
phosphorous
What makes the phosphorus cycle different from the nitrogen and carbon one?
phosphorous cycles from the environment to organisms and back into the environment; found in water, rocks, and organisms
The ______________ cycle does not involve the atmosphere.
phosphorus
In an aquatic ecosystem ___________ perform photosynthesis, converting the carbon dioxide from the atmosphere into sugar.
phytoplankton
A whale eating krill is an example of ____.
predation
In predation, the species who benefits is known as the _____ and the species who is harmed is known as the _____.
predator prey
Carbon is the _____________ element of the Periodic Table.
sixth
Which of these contain carbon?
sugar and graphite diamonds the atmosphere and shells of marine animals
Nitrogen-fixed bacteria are found on legume plants, such as peanuts and soybeans in ___ ecosystems.
terrestrial
What is the phosphorous cycle?
the process where phosphorous cycles from the environment to organisms and back into the environment
What is a niche?
the unique role a species plays in an ecosystem encompasses a species' physical home, the environmental factors the species needs to survive, and all interactions with other species in the same ecosystem
What is niche?

How is symbiosis similar to mutualism and commensalism?
they are all relationships in which one species benefits from another species and harms the other
