what type of movememt does this diagram show?
passive transport where molecules move from areas of higher concentration to lower
what would likely happen to a cell if lost its membrane
it wouldn't be able to bloke harmful molecules
what percentage of avaliable energy would be transferred from one level to next?
10%
if all red tailed hawks, coyotes, and rattlesnakes removed from ecosystem what effect on the population on cottontalis?
growth without predictors but will eventually stabilize due to lack of resources
what factors should the city consider when choosing removal effort?
the effect on the environment
example of transport that are represented in this diagram
osmosis, simple diffusion, and facilitated diffusion
how does structure of cell membrane help cell maintain homeostasis?
The arrangement of phospholipids separates the intracellular fluid from the extracellular fluid.
3 reasons why less energy is passed form one trophic level to the next?
energy used organism to preform life functions
energy stored within organism
energy lost as heat to the environment
what are the reactants and products of cellular respriation?
reactant: sugar and oxygen
products:water and carbon dioxide
how does kudzu effect on biodiversity of the areas in United States where it grows?
decreases biodiversity by decreasing the avaliable space and resource of native plants
what will most likely happen to the cell because of the movement of water?
cell will shrink. water will exit the cell
What is the interaction between the cell membrane and the chloroplast in this plant cell?
The cell membrane allows for the diffusion of carbon dioxide needed by the chloroplast for photosynthesis.
explain why there's limited number of organism that the ecosystem can sustain?
small amount of energy transferred form one level to the next in ecosystem
what are the reactant and product of photosynthesis
reactants: water and carbon dioxide
product: sugar and oxygen
what happens to energy moving up a energy pyramid?
energy is lost to the environment as heat but not distroyed
how do proteien in the cell membrane help the cell maintain homeostasis?
Which two organelles are the most responsible for food and energy production in plants?
chloroplast and mitochondria
two ways carbon dioxide directly into the atmosphere?
decomposition organism
respriation form organism(cellular respiration)
in the ____ a plant cell used chemical reactions to break down the food that was made during ____
cellular respiration and mitochondrion
how does the flow of energy in energy pyramid support the law of energy?
energy changes form as it flows through an ecosystem but the total amount of energy stays the same
carbon dioxide produced in a cell through cellular respiration what best predicts the movement of carbon dioxide the cell membrane in animal cell?
overflow of carbon dioxide out the cell
compares how matter and energy move among organism in food chain?
matter cycles among organism and energy flow among organism on the system both matter and energy conserved.
the affect on carrying compasity of ecosystem?
will decrease because there will be less food available for many organism
is the claim made by scientist in the passage above supported by the data below?
yes because most of the population of organism in ecosystem increased
