Abiotic vs. Biotic
Abiotic
A tree is an example of what kind of living thing? (i.e., producer, consumer or decomposer)
Producer
True or false: photosynthesis can still happen without sunlight
Which of the following organisms can do cellular respiration: producers, consumers, decomposers, or all of them?
All of them
Can the total carbon in a closed ecosystem change? Yes or no
No!
Is sunlight biotic or abiotic?
A mouse is an example of what kind of living thing? (i.e., producer, consumer, or decomposer)
Consumer
Name one example of a living thing that does photosynthesis
Any type of plant you named is correct!
What is produced through cellular respiration?
True or false: energy storage molecules contain carbon
True
Is a deer skull biotic or abiotic?
Biotic
What do organisms produce through photosynthesis? Name one of the two things
Oxygen and energy storage molecules
True or false: cellular respiration can still happen without sunlight
True
What is the name for the carbon that is in the air?
Carbon dioxide
When an animal does cellular respiration, what direction does the carbon move? From biotic to abiotic matter or from abiotic to biotic matter
From biotic to abiotic
Producer
Name 2 things that organisms need to be able to photosynthesize
Sunlight, water, carbon dioxide
Name one of the two things that an organism needs to complete cellular respiration.
There are 30 units of carbon in a closed ecosystem. There are 20 units of carbon in biotic matter and 10 units of carbon in abiotic matter. 5 units of carbon leave biotic matter.
How many units of carbon are in abiotic matter at the end?
15 units of carbon
Name (1) a material that a desk could be made out of that is abiotic and (2) a material that a desk could be made out of that is biotic
(1) metal, plastic, glass, stone, etc. and (2) wood
Why will an ecosystem fail if there are no decomposers?
There will not be enough carbon dioxide made through cellular respiration for producers to be able to photosynthesize
What would happen if photosynthesis stopped working in an ecosystem? Be specific!
Everything would die because there would not be enough energy storage molecules and/or oxygen to support life
Why do organisms need to do cellular respiration? What's the purpose of it for that individual organism?
To release energy stored in energy storage molecules
Which of the following contains carbon and is also a type of energy storage molecule: ammonia, glucose, sodium, or acetate
Glucose
