Where do primary producers get their energy from?
Solar energy
100
What are the reactants of photosynthesis?
Carbon dioxide, water, sunlight
100
What are the reactants of cellular respiration?
glucose and oxygen
100
What is the term for organisms that are able to manufacture organic nutrients on their own from the abiotic environment?
autotrophs
100
What is biodiversity?
variety of life in a given ecosystem
200
What are the 5 trophic levels?
primary producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers
200
What are the products of photosynthesis?
glucose and oxygen
200
What are the products of cellular respiration?
carbon dioxide, water, ATP
200
What is the term for organisms that must consume biotic nutrients?
Heterotrophs
200
What are greenhoue gases?
methane, carbon dioxide, water vapor
300
Why can't organisms produce unlimited population sizes?
limiting factors/resources
300
What are the three limiting factors of photosynthesis?
light intensity, CO2 concentration, temperature
300
What is the chemical formula for glucose?
C6H12O6
300
What is the phenomenon called that pertains to 90% of energy being lost at each trophic level?
10% rule
300
what are three ways humans negatively impact biodiversity?
deforestation, pollution, overfishing/hunting, invasive species, climate change acceleration
400
What is the carrying capacity of the Red Wolf population?
110
400
Where do the carbon atoms in glucose primarily come from?
carbon dioxide from the atmosphere
400
which organelles are involved in energy conversion?
mitochondria and chloroplasts
400
What term describes the maximum number of individuals an ecosystem can support long term dependent upon available energy, minerals, and oxygen?
Carrying capacity
400
What is the greenhouse effect?
Solar energy enters atmosphere and the heat gets trapped, warming the Earth's surface
500
If the mass of the rabbits in the ecological pyramid is 1,100kg, what would you expect the mass of the hawk to be?
11
500
What process brings in carbon from the atmosphere?
photosynthesis
500
What is the definition of photosynthesis, cellular respiration, and the relationship between the two?
autotrophs use sunlight to synthesize glucose from CO2 and H2O
autotrophs and heterotrophs use cellular respiration to convert glucose into ATP for cellular processes
Photosynthesis makes glucose for cellular respiration in autotrophs. Heterotrophs get glucose from other organisms for cellular respiration.
500
What is the difference between aerobic and anaerobic respiration and what are the two types of anaerobic respiration?
aerobic-with oxygen
anaerobic-without oxygen
lactic acid fermentation-muscles, no CO2
alcohol fermentation-yeast, CO2
500
What are two carbon source and carbon sink examples?
forest fires, burning fossil fuels, volcanic activity, deforestation
oceans, soil, meadows, forests, wetlands
