abiotic
|
non-living
|
|
absorption
|
to soak up
|
|
aphid
|
an insect that eats and drinks nector from plants they live on
|
|
bacteria
|
domain of uni-cellular prokaryokes that have cell walls containing peptidoglycons
|
|
biomass pyramid
|
represents the amount of potential food available for each trophic level in an ecosystem
|
|
biosphere
|
part of earth in which life exists
|
|
carbon cycle
|
4 types of processes that move through this cycle: 1.biological
2.geochemical 3.mixed bio-geochemical 4.human-act |
|
carnivore
|
animal that eats meat
|
|
commensalism
|
symbioyic relationship by which one member of the association benefits and the other is neither helped nor harmed
|
|
consumer
|
something that eats something else
|
|
decomposition
|
a reaction in which a compound breaks into 2 or more simpler substances
|
|
ecology
|
scientific study of interactions among organisms and between organisms
|
|
biomass
|
total amount of living tissue within a given trophic level
|
|
food chain
|
shows one way flow of energy
|
|
food web
|
network of complex interactions
|
|
fungi
|
kingdom composed of heterotrophs
|
|
herbivore
|
animal that eats plants
|
|
host
|
organism being used
|
|
mutualism
|
symbiotic relationship in which both species benefit from the relationship
|
|
describe the impact of human activities on the carbon cycle
|
*burning fossil fuels
|
|
state the roles of photosynthesis and respiration on the carbon cycle
|
carbon dioxide is taken in by plants during photosynthesis and is given off by both plants and animals during respiration
|
|
indentify the role of bacteria in the nitrogen cycle
|
only certain types of bacteria which live in the soil and on the roots of plants called legumes, convert nitrogen gas into ammonia in a process known as nitrogen fixation
|
|
identify the changes that occur during ecological succession
|
ecosystems are constantly changing in response to natural and human disturbances .as an ecosystem changes, older inhabitants gradually die out and new organisms move in, causing further changes in the community
|
|
distinguish among carnivores, herbivores, and omnivores
|
carnivores-animals that eat meat
herbivores-animals that eat plants omnivores-animals that eat both plants and animals |
|
distinguish among commensalisms, mutualism, and parasitism
|
commensalism-one benefits, the other is not harmed
mutualism- both species benefit parasitism-one lives on another and consequently harms it |
|
desribe the flow of energy through a food web
|
each consumer depends on the trophic level below it for energy
|
|
distinguish between a food web and a food chain
|
a food web links all food chains in an ecosystem
|
|
identify actions that can help preserve the biosphere
|
*recycle
|
|
state the ranges of pH associated with acids, bases, and neutral solutions
|
1-6= increasing acidic
7= neutral 8-14= increasing basic |
|
distinguish between organic and inorganic molecules
|
organic- with carbon
inorganic- without carbon |
|
compare carbohydrates, lipids, nucleic acids, and proteins
|
carbohydrate- compound made up of carbon, hydrogen, and oxygen atoms
lipids-macromolecules made mainly from carbon and hydrogen atoms nucleic acids- macromolecule containing hydrogen, oxygen, nitrogen, carbon, and phosphorus proteins-macromolecule that contains carbon, hydrogen, oxygen, and nitrogen |
|
identify the building blocks of proteins and nucleic acids
|
proteins-amino acids
nucleic acids-nucleotides |
|
state the function of the flagellum
|
whip like structures used for movement
|
|
state the functions of chloroplasts, mitochondria, and ribosomes
|
ribosomes- small particles of RNA and protein found throughout the cytoplasm
mitochondria-organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use |
|
identify the roles of a membrane in osmosis and homeostasis
|
osmosis- allows substance to enter or exit
homeostasis- helps keep internal conditions relatively constant despite changes in external environment |
|
distinguish between prokaryokes and eukaryokes
|
prokaryokes- have genetic material that is not contained in a nucleus.(does not contain nucleus)
eukaryokes- contain a nucleus in which their genetic material is seperated from the rest of the cell.(has a nucleus) |
