25
What’s the definition of abiotic matter?
matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
26
What are primary consumers?
only eat producers
27
What are secondary consumers?
must-eat primary consumers but, can eat producers
28
What are tertiary consumers?
must eat secondary consumers and/or tertiary consumers, can also eat producers + primary consumers
29
What’s the definition of glucose?
an ESM made of carbon, hydrogen, and oxygen atoms
30
What’s the definition of carbon dioxide?
a molecule made of carbon and oxygen atoms
31
How can polluted water prevent underwater plants from performing photosynthesis?
With polluted water, underwater plants would be unable to receive as much sunlight, decreasing photosynthesis
32
What’s the definition of fat?
an ESM made up of fatty acids
33
What’s the definition of photosynthesis?
the process by which producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose
34
Where is carbon found in an ecosystem?
In abiotic and biotic matter
35
What is the definition of energy?
The ability to make things move or change
36
What is the definition of biotic matter?
matter that makes up the living and dead organisms of an ecosystem
37
What’s the definition of producers?
an organism that can make its ESM
38
What are reactants? What are products?
Rectants - something that is used in a chemical reaction/process Products - the result of completing a chemical reaction/process
39
What is the definition of a chloroplast?
organelle where photosynthesis happens
40
The amount of life that can exist in an ecosystem depends on what?
The amount of sunlight they recieve
41
What is unique about glucose by comparison to other ESMs?
It can make other ESMs
42
What is glycogen and how is it different from starch?
Glycogen is an ESM and Isnt made by producers (consumers & decomposers) and can’t be used for a long time
43
What atoms are all esms made of?
Carbon, hydrogen, oxygen
44
Name two things that the esm fat is used for.
1. Long term energy storage (emergency storage) 2. Important in cell membrane
45
What is a decomposer’s purpose? Why is it crucial to the success of an ecosystem?
Decomposers break down dead matter and put nutrients into the ecosystem adn then release CO2. It’s crucial because producers need CO2 for doing photosynthesis. They also make nitrogen available to the ecosystem which is essential for plant growth
46
How do decomposers get esms?
When breaking down dead matter
47
What element (other than carbon) is a crucial nutrient for plant growth and is released by decomposing dead matter?
nitrogen
48
What is the definition of cellular respiration?
the chemical reactions between oxygen and glucose that release energy into the cells
49
In a closed ecosystem if carbon _____________ in one part of the system, then it must _____________ somewhere else.
Decreases, increase
50
What is the definition of fossil fuels?
made up of carbon-rich matter from dead matter
51
What do fossil fuels release when burned?
carbon
52
Earth is a ________________ ecosystem
enclosed
53
Fossil fuels are what type of matter?
biotic
54
How many atoms of carbon are required in the inputs of photosynthesis?
6
55
How many atoms of hydrogen are in the reactants of cellular respiration?
12
56
What organisms make starch?
Producers
57
What organisms make fat?
ALL of them (Producers, consumers, and decomposers)
58
What organisms make glycogen?
Consumers and decomposers
59
What is the Kreb's Cycle also known as?
Citric Acid Cycle
60
Which comes first, the light independent or dependent reaction?
The light dependent reaction
