Understand the definitions and what happens
Ecosystem
All the biotic and abiotic things interacting in a particular area
System
A set of interacting parts that form a whole
Biotic matter
Matter that makes up the living and dead organisms of an ecosystem
Abiotic matter
Matter that makes up the nonliving parts of an ecosystem, such as water, air, and rocks
Organisms
Living things
ESM
A molecule that organisms can use to release energy
Energy
The ability to make things move or change
Molecule
A group of atoms joined in a particular way
4 types of ESMs
Glucose, starch, fat, and proteins
Glucose
An ESM made of carbon, hydrogen, and oxygen atoms
Starch
An ESM made of many glucose molecules combined together
Fat
A type of ESM made up of fatty acids
Producers
An organism that can make its own ESMs
Carbon
A type of atom that makes up molecules such as carbon dioxide and ESMs
Carbon Dioxide
A molecule made of carbon and oxygen atoms
Photosynthesis
The process in which producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose
What happens through photosynthesis?
Producers take carbon from abiotic matter and move it into biotic matter in the form of glucose.
Reactants (inputs)
What is USED in a chemical reaction or process
Products (outputs)
What we GET when the process or chemical reaction is finished
Chloroplasts
ORGANELLE where photosynthesis happens
In which types of organisms are chloroplasts SOLELY found?
Producers
Consumer
An organism that needs to eat to get ESMs
Primary consumer
Only eats producers
Secondary consumer
MUST eat primary consumers, but can also eat producers
Tertiary consumer
An organism that MUST eat secondary/tertiary consumers, but may also eat primary consumers and producers
The amount of organisms an ecosystem can support depends on the amount of __________ it receives.
Sunlight
Glucose is only MADE by what?
Producers
Glucose is used to create what?
Starch
Producers are the only ones that make what LARGE ESM?
Starch
What molecules is starch made up of?
Carbon, hydrogen, and oxygen
Starch stores what to be used for energy later?
Glucose
All types of organisms (producers, consumers, decomposers) make what?
Fat
Fat is made up of what atoms?
Carbon, hydrogen, and oxygen
What molecule is fat made up of?
Fatty acids
Fat is a long-term energy storage, but what is not?
Starch
Fat is very important to the cell membrane. Why?
It makes a part of the cell membrane
Glycogen is the only ESM made by consumers and decomposers. It’s made of what?
Carbon, oxygen, and hydrogen
Starch stores glucose for energy later for producers. What stores glucose for energy later in consumers and decomposers?
Glycogen
Plants make starch, we make glycogen. Why?
The difference in cells
Equation for photosynthesis
6CO2+6H20+Sunlight -> 6O2+C6H12O6 (6CO2 + 6H2O → C6H12O6 + 6O2)
The equation for cellular respiration
6O2+C6H12O6 -> ATP Energy, 6CO2, 6H20
The two major reactions that take place are…?
Light-dependent reaction, light-independent reaction
Thylakoid
A part of the chloroplast where light-dependent reaction occurs
Stroma
A part of the chloroplast where light-independent reaction occurs
A chloroplast is an _________; stroma and thylakoids are not.
Organelle
In cellular respiration, there are THREE major steps:
Glycolysis (cytoplasm), Krebs Cycle (mitochondria), Electron Transport Chain (mitochondrial membrane)
Net ATP of Glycolysis?
2
Net ATP of Krebs Cycle?
2
Net ATP of Electron Transport Chain?
34
Cellular respiration
The chemical reaction between oxygen and glucose that releases energy, carbon, and water into cells
