Cellular Respiration and Chemosynthesis
process that allows all organisms to convert nutrients in food (glucose) into a usable form of energy (ATP)
What is Cellular Respiration?
CO2 + H2O + Sunlight = Glucose (C6H12O6) + O2
What is the equation of photosynthesis?
shows series of intertwined food chains
What is a food web
refers to the feeding level(s) of an organism and it’s position in a food chain/web
what are tropic levels?
process by which dead organic matter rots and then is broken down into plant nutrients and recycled back into the environment
What is decomposition?
Glucose (C6H12O6) + O2 = CO2 + H2O + Energy (ATP) = aerobic respiration (needs oxygen)
What is the equation for Cellular Respiration?
primary source of energy in almost all food webs
What is Photosynthesis?
shows 1 sequence of organisms feeding on other organisms
what is a food chain?
Only 10% of the energy available at one trophic level is transferred to the next trophic level = 90% of energy available is LOST
What is the 10% rule?
compares the amount of energy passing through each tropic level at a given time
What is the Pyramid of Energy?
process where bacteria oxidizes hydrogen sulfide (H2S) to produce glucose (C6H12O6)
What is Chemosynthesis?
to convert light energy (from the sun) into chemical energy stored in food(i.e. glucose, carbohydrates, organic substances, etc.)
What is the purpose of photosynthesis?
Only a small percentage of energy captured from the sun is used to make organic substances like glucose/carbohydrates by primary producers such as phytoplankton
How is energy lost along food chains?
the total energy captured by primary producers from the sun
What is gross primary production or GPP?
compares the number of organisms at each trophic level
What is the Pyramid of Numbers?
CO2 + H2O + H2S = C6H12O6 + Sulfur compounds (i.e. H2SO4 = Sulfuric Acid)
What is the equation for Chemosynthesis?
One place photosynthesis can’t occur
What are Deep Sea Food Webs?
the biological material contained within living organisms
What is Biomass?
Net Primary Production(NPP) is...
the amount of energy available to the next trophic level
animal that hunts, catches, kills and/or eats another animal
What is a Predator?
Happens in ecosystems that do not have access to light = Hydrothermal Vents
Where does Chemosynthesis occur?
Produces Gluscose
Hint- 2 answers
What is Photosynthesis and Chemosynthesis?
Consumers depend either directly or indirectly on the energy captured from the sun by primary producers. The primary productivity of an ecosystem affects all trophic levels.
How does Productivity affect food Chains?
the rate of biomass produced per unit area/volume per year
What is Productivity?
organism that consumes a secondary consumer
What is a Tertiary Consumer?
