high
low
balanced
all of the above
Turgor pressure is
water in a plant
a process in photosynthesis

chemical, mechanical
electrical, chemical
chemical, radiant
radiant, chemical
Identify how energy is passed through an energy pyramid
energy is passed from organisms in the bottom level to the organisms in the top level
energy is passed from organisms in one level to the level immediately above them
energy is passed from organisms on the top level to the levels below them
energy is passed between all of the levels equally
A food chain is
a series of interconnected food webs
a sequence of organisms (in a straight line) through which nutrients and energy pass as one organism eats another
a group of species that feed off of the same prey
a series of interconnected food chains
How does biodiversity sustain an ecosystem?
the greater the biodiversity (variety of species) the greater the chance of sustainability
the greater the biodiversity (variety of species) the less the chance of sustainability
the less the biodiversity the greater the sustainability due to less predators
the greater the biodiversity the less the sustainability due to more predators
Photosynthesis is ________ + __________ + _________ = _________ + _____________

Secondary succession occurs in an area where _________________________
a disturbance or natural disaster such as a wildfire reduces the biodiversity in an already established ecosystem
a lifeless region is due to lava flow
more than one disturbance affects an ecosystem
