What is an ecosystem?
What is...a community of living organisms (biotic factors) interacting with each other and their non-living physical environment (abiotic factors)?
100
The process that converts solar energy into chemical energy.
What is...photosynthesis.
100
The cutting down of forests.
What is...deforestation?
100
The reactants (ingredients) of photosynthesis.
What are...light energy, carbon dioxide (CO2), and water (H2O)?
200
What is "carrying capacity?"
What is...the maximum population size of a species that the environment can sustain?
200
The process that converts sugar into energy in the form of ATP.
What is...cellular respiration?
200
The type of gas that builds up in the atmosphere to contribute to climate change.
What is...carbon dioxide (CO2)?
200
The reactants (ingredients) of cellular respiration.
What are...glucose and oxygen?
300
What are three factors that can influence carrying capacity?
What are...food availability, water availability, space, predators, weather/climate, mate availablity?
300
Describe how carbon cycles through photosynthesis and cellular respiration.
300
List the main sources of carbon dioxide emissions.
What are...cars, factories, burning fossil fuels, making electricity?
300
The products of photosynthesis.
What are...glucose and oxygen (O2)?
400
Explain how food availability can impact carrying capacity.
What is...the available amount of food limits how big a population can grow, but more food can cause a population size to increase.
400
The type of cellular respiration that DOES NOT use oxygen.
What is...anaerobic respiration?
400
The effect that deforestation causes regarding carbon cycling.
What is...less carbon removed from the atmosphere and less carbon stored in the trees?
400
The products of cellular respiration.
What are...carbon dioxide (CO2), water (H2O), and ATP?
500
Describe how competition between species influences population sizes.
What is...populations can only get as big as the available resources. If two or more species are competing for those resources, their populations can only get so big.
500
Only this amount of energy is transferred between trophic levels.
What is...10%?
500
This process is more significant in the summer.
What is...photosynthesis?
500
Identify if oxygen (O2) is a reactant or product of cellular respiration and photosynthesis.
Oxygen is a product of photosynthesis and reactant of cellular respiration.
