a group of similar organisms that can interbreed and produce fertile offspring
What is species
100
rate of production of biomass
What is productivity
100
movement of water from deep in the ocean to the surface layer, where the
nutrients become available to primary producers
What is upwelling
100
used to find the age of a sample of
cora
What is Carbon dating
100
a theory suggests that the outer crust of the
Earth consists of a number of separate plates which ‘float’ on the underlying layer
What is theory of plate tectonics
200
the numbers of different species present and the range of habitats and ecosystems
What is biodiversity
200
what percentage of energy is transferred from one trophic level to another
What is 10%
200
flow of water from land, arising from rain or from melting snow and ice
What is runoff
200
what did Charles Darwin classify coral reefs as
What is fringing reefs, barrier reefs, and atolls
200
formed along tectonic plate boundaries where one plate is forced under
another plate
What is Ocean trenches
300
corals and zooxanthellae,
cleaner fish and grouper, and chemosynthetic bacteria and tube worms are examples of
What is symbiosis
300
where is the producer located in a Ecological pyramid
What is base
300
One of the ways in which nutrients are removed from the surface waters
What is uptake by primary producers
300
the study of landforms and the processes involved in shaping
them
What is geomorphology
300
occur in the deep ocean, typically along mid-ocean ridges where two tectonic
plates are diverging
What is Hydrothermal vents
400
1.occupy the first trophic level, 2.occupy the second trophic level 3.occupy the third trophic
level
What is 1.Producers 2.primary
consumers 3 secondary consumers
400
captures the chemical energy of dissolved minerals, and that
chemosynthetic bacteria at hydrothermal vents making energy available to the food chain
What is chemosynthesis
400
biological use for nitrogen
make proteins
400
what is Artificial reefs function
to submerged breakwater, dissipate wave energy, reducing coastal
erosion and protecting anchored boats.
400
relatively flat areas of the ocean floor, situated between ocean trenches and
continental rises
What is Abyssal plains
500
role of an organism in an ecosystem
What is niche
500
equation that represent energy source which can be
transferred to higher trophic levels.
What is NPP = GPP – R
500
biological use for calcium
make bones, corals and shells
500
absorb the energy of waves and so protect the shoreline from erosion
What is coral reefs
500
a semi-enclosed coastal body of water, which has a connection with
the sea and within which sea water is diluted with fresh water derived from land drainage.
