how can human activites affect the biodiversity of an ecosystem?
less people in an area
more room for animals to live where they need to to be able to survive on their own
population growth, the more people the more space you need
what is a biome?
a large region classified by the interaction of living organisms, climate, and geographical features
describes factors in an environment that are not and have never been living, including temp, light, precipitation
describes factors in an enviornment that are associated with living organisms
define abiotic factors
living organisms
define biotic factors
describes factors in an environment that are associated with living organisms
nonliving organisms
whats an example of a biome?
aquatic
desert

plant
water
what is an example of a biotic factor?
rock
insect
define invasive species
animals that belong to a certain ecosystem

factors in an environment that are not and have never been living, including temp, light, precipitation
what is an example of an invasive species
cane toad
lion
what characteristics do invasive species share?
they are all harmful
they are all native
they all are new to an area
A & C
define native species
a species considered to be not naturally found in an environment

a rock
example of native species?
exotic plants
a rock that you can buy from the store
define tradegy of the commons
overfishing
a theory stating that the more people there are who have unrestricted access to a common resource, the more they will exploit it, without considering the consequences
when a ton of fish died do to poison
example of tradegy of the commons?
pants
earths atmosphere
how is phytoplankton different from zooplankton?
zooplankton is in-capable of doing photosynthesis
they both are the same
phytoplankton does cellular respiration
what are the first 4 trophic levels on the energy pyramid from bottom to top?
producer, primary consumer, secondary consumer, teritiary consumer
primary consumer, secondary consumer, teritiary consumer, producer
name 2 processes that release carbon into the atmosphere
burning of carbon fuels
cellular respiration
a & b
absorption
name 2 processes that remove carbon from the atomosphere
photosynthesis, dissolution
define law of conservation of mass
matter cannot be created nor destroyed
matter is matter
what happens to the amount of carbon as it moves through the atmosphere?
it increases
it stays the same
it decreases
what is a carbon reservoir?
a machine that makes carbon go into to atmosphere
carbon-storing feature that exchages carbon with other reservoirs
what is the purpose of cellular respiration
provides energy in the form of ATP
to help plants
for human resources
what is the purpose of photosynthesis?
to help plants die
converts solar energy into chemical energy and then stores that energy for further use
what is the equation for photosynthesis
Co2 + C6C6 + light energy
6CO2 + 6H2O > C6H12O6 + 6CO2
whats the equation for cellular respiration
C6H12O6 + 6 O2 > 6 CO2 + 6 H2O + energy
