Photosynthesis
Definition of photosynthesis
What is the process by which most producers use sunlight to synthesize foods from carbon dioxide and water?
definition of cellular respiration
what is the main process that converts glucose into ATP
difference between aerobic and anaerobic respiration
what is aerobic (with oxygen); anaerobic (without oxygen)
Why is a pyramid shape used to represent energy and biomass
Because it represents the idea that as you move up the pyramid, the number of organisms and energy the organism obtains decreases.
two main stages of photosynthesis
What is light-dependent reaction and light-independent reaction
Organisms that perform photosynthesis
What is plants, some protists (algae), some bacteria (cyanobacteria)?
organisms that do cellular respiration
what is plants, animals, and all other eukaryotes
organisms that do anaerobic respiration
what is animals, bacteria, yeast
How does energy flow through each level of an energy pyramid?
What happens in the light reactions
Light energy and water are converted into oxygen
the parts of the chloroplast
what is thylakoids, stroma, and grana
the reactants of cellular respiration
what is glucose and oxygen
byproduct of lactic acid fermentation
what is lactate (lactic acid)
autotrophs acquire energy through...
making their own energy
ATP molecules are produced during glycolysis
2
Definition of chloroplast & why is it important
pigment that absorbs light energy - it is responsible for capturing light and converting it to sugar and oxygen
products of cellular respiration
what is carbon dioxide and water
byproduct of alcoholic fermentation
what is ethanol
4 types of heterotrophs
carnivores (meat), herbivores (plants), omnivores (plants and meat), detritivores (dead organic material).
three main stages of cellular respiration
glycolysis, Krebs cycle, electron transport chain
chemical equation for photosynthesis
what is Light energy + 6CO2 + 6H2O → C6H12O6 + 6O2
chemical equation for cellular respiration
what is C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
more efficient: cellular respiration or fermentation? Why
what is cellular respiration is more efficient because 36-38 ATP molecules are created (as opposed to only 2 with fermentation).
If only 10% of energy is transferred from one trophic level to the next, where does the other 90% go?
heat and metabolic processes
Suppose a producer contains 9234 J of energy. How much energy will be consumed by the primary consumer? secondary? tertiary?
primary 923.4 J
secondary 92.34 J
tertiary 9.23 J
