AICE MARINE SCIENCE FULL SOLUTION
QUESTIONS AND ACCURATE ANSWERS
PREPARATION RESOURCE
●● Ecosystem
Answer: living organisms and the physical and chemical factors which
influence them (abiotic and biotic components)
Example: A rocky shore
●● Habitat
Answer: the place where organisms live
Example: the area surrounding a hydrothermal vent
●● Population
Answer: consists of organisms of the same species, usually defined as
living in the same area
Example: a population of ghost crabs
●● Community
Answer: includes all the different species living in a habitat at the same
time
,●● Species
Answer: a group of similar organisms that can interbreed and produce
fertile offspring
●● The Name
Answer: First = generic name, refers to the genus
Second = specific name, refers to the species
●● Biodiversity
Answer: takes into account the numbers of different species present and
the range of habitats and ecosystems
Example: Coral reefs have a high biodiversity w/ many different species
present
●● Ecological Niche
Answer: the role of an organism within an ecosystem, taking into
account its relationships with other organisms
●● Symbiosis
Answer: a relationship b/w two different organisms, where both derive
some benefit from the benefit
Example: corals and zooxanthellae
, ●● Parasitism
Answer: a relationship b/w two organisms where one, the parasite,
obtains benefit at the expense of the other, known as the host, which is
usually harmed by the relationship
Example: Tuna and Nematodes
●● Parasites
Answer: Split into two groups: Ectoparasites and Endoparasites
-Ectoparasites: live on the outside of their host (Fish lice)
-Endoparasites: live inside their host (Nematodes)
●● Producers
Answer: are able to synthesize organic substances from simple organic
compounds, using light energy from the sun, in the process of
photosynthesis
Example: green plants and algae
-They provide food for all other organisms in food chains and food webs
●● Consumer
Answer: an organism that obtains its energy requirements by feeding on
other organisms
●● Primary Consumers
