100
Which graph represents increased population growth?
Pyramid A
200
What chemical was put into the atmosphere through products like propellants in aerosol cans, and refrigerants, and what are the effects of it?
Chlorofluorocarbons (CFC's). They thinned the ozone layer through binding and unbinding with the ozone and O2.
200
Amount of a certain species in an area.
what is population?
200
participation, rivers/ponds, mountains/ hills.
what is an A-biotic factor?
200
the percent of energy is transferred between each trophic level.
what is 10% of the energy?
200
What two organisms grow exponentially?
Bacteria and Humans
300
Describe the process that happens with eutrophication.
The process of putting to much nutrients into a body of water, usually nitrogen from farmlands. this usually goes something like
300
a substance that builds over time in organisms that are consumed by other organisms.
what is biomagnification?
300
all living things.
what is the biosphere?
300
an organism that has a different role in the trophic level and ends up eating all of the animals no matter thee position in the food web.
what is a scavenger?
300
As the predator population increases, the prey population...
...decreases
400
the ozone thinning is not climate change because?
because the ozone only reflects one thing, ultra violet light. meaning that the heat that still comes in is not effected by the ozone.
400
predators, hunting, and food scarcity.
what is a limiting factor?
400
a organisms certain role in the environment to decrease the competition.
what is a niche?
400
If grass has 100% energy and it is a producer, what percent will the tertiary consumer have?
The tertiary consumer has 0.1% of the grass' energy.
400
Which graph represents the growth of rabbit populations?
Logistical growth
500
the reason there is a rise in temperature around the world, the culprit of the continental ice caps melting, the reason there is more carbon dioxide in the atmosphere.
what is fossil fuels?
500
Producers use sunlight and convert it into Oxygen and glucose, and emit carbon dioxide in the process.
what is photosynthesis?
500
Describe the difference between mutualism and commensalism
Mutualism is where both organisms help each other, and commensalism is where only one organism benefits and the other is neither harmed nor hurt.
500
why is there so few levels in the food chain/ food web?
there is not a lot of levels in the food chain because less and less of the energy ends up making it up the food chain/ food web.
