carbon cycle
what is the four spheres?
what is the hydrosphere,geosphere,biosphere, and atmosphere?
why are some elephants tuskless?
who was the keystone species of the kelp and urchin ecosystem?
what is otters?
definition of trophic cascade?
a ripple effect that occurs throughout an ecosystem when a predator is added or removed
inputs and outputs of photosynthesis
what is carbon dioxide,and water to glucose and oxygen?
why did woolly mammoths die out?
due to climate change and ecosystems not adapting and losing their primary food source.
what would it be like if the otters disappeared?
overpopulation in urchins and eats all the kelp and thus dies out due to no food.
define diffusion?
the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration
what are inputs and outputs of cellular respiration?
what is oxygen and glucose to carbon dioxide and water?
how were being tuskless benificial?
it made them less of an target for illegal ivory poaching.
what are trophic levels?
an organism's specific position in an ecosystem's food chain or energy pyramid, defined by how it obtains its energy (ex. autotrophs/producers and heterotroph/consumers)
define adaption?
any physical, physiological, or behavioral trait that helps an organism survive and reproduce in its specific environment
what are common forms carbon takes?
examples like ceeohtew idrk
why was tusks benificial?
they digged water out, gave dominance, and defense for themselves and others.
how does carbon/energy/nutrients flow through an ecosystem?
by eating eachother (ex, tree goes to an deer, deer goes to the wolf, then they die and goes to the decomposer and does it all over again)
define natural selection?
the primary mechanism of evolution
fossil fuels definition?
what is natural, carbon-rich energy sources formed from the ancient, buried remains of prehistoric plants and animals? (basically long ago dead animals turned into rocks like coal and oil)
how was mammoths benificial?
maintained grasslands which helped absorb more carbon dioxide and ecosystems like the stepe tundra thrive.
ecosystem resiliance and stability
ecosystem's capacity to absorb disturbances and maintain its core functions. (ex like the otter to the urchins kinda)
define variation?
the differences in physical traits, genetics, or behaviors between individual organisms of the same species
