feeds n living or recently unliving organisms
3two types of consumers
detritivores and saprotrophs
4detritivores
feeds on dead organic matter with a muth
5saprotrophs
feeds on dead organic matter without a mouth
6heterotroph
ogranisms that cannot make its own carbon compounds froms simple substances. organisms that obtain organic compounds from other organisms
7autotrophs
ogranism that can make its own carbon compounds from simple substances. ogranism that make therir own organic compounds from inorganic substances
8three types of consumer
herbivore, carbinore, omnivore
9detritivore

17what are primary heterotropsh
species that eats autotrophs
18que 2nd heterotroph
species that eats primary heterotroph
19why are some animals (like lions) exist at more than one trophic leve
they eat the primary and secondary heterotroph
20name four ways energy is loss
cell/ body activity, heat, respiration, excretion
21how is energy entered in ecosystems
through producers
22can organisms keep 100% of the energy they consume
no
23what is biomass
the total mass of a group of organisms
24why does a good chain have a max of 4-5 levels?
energy will run out
25what is the avg energy that is transferred from one level to another
10%
28what is organic molecules
compounds that contrain carbon, hydrogen, and oxygen
29what is inorganic compounds
compounds that does not have ALL three components. so an example is H20
30what is carbon sink
carbon that is stored long term
31what are greenhouse gasses
any gases that trap heat in the atmosphere, just like the glas walls and ceiling of a greenhouse trap heat inside the struture to cause a warming effect
32what is an effect of higher earth temp
co2 is dissovled in water, and carbonic acid is formed. the pH level of the ovean has decreased.
