Abiotic vs. Biotic Factors
They are any non-living component in an ecosystem. ex: rocks, pH levels, water, temperature, etc
What is an abiotic factor?
This is the movement of water above, on, and below the surface of the earth.
What is the hydrologic cycle?
This is the burning of fossil fuels.
What is combustion?
Another name for plants and autotrophs. The base of the trophic pyramid.
Choose the correct answer:
Which of the following is NOT an abiotic factor?
A. pH levels
B. Temperature
C. Mold
D. Oxygen
C. MOLD
Both rotting logs and decomposing animals are an example of these.
What are biotic factors?
This is when water sticks to water.
What is cohesion?
This is the process by which plants take in or remove carbon from the atmosphere to create an organic compound.
What is photosynthesis?
It is the driving force of energy transfer on earth.
What is the sun?
In order to get a 3 on a CER response, students provide this much evidence.
2 pieces of evidence
It is made up of animals, plants and bacteria as well as the physical and chemical environment they live in.
What is an ecosystem?
Electronegativity between Oxygen and Hydrogen give water this property.
What is polarity?
This is the process by which carbon is broken down from an organic compound and returned to the atmosphere as carbon dioxide.
What is cellular respiration?
The percentage of energy that is transferred between each level of the trophic pyramid.
What is 10%.
This is the level of consumer that receives the largest amount of energy.
What is the primary consumer?
Answer this: In a marine (ocean) ecosystem which of the following abiotic factors could affect the sea life there?
1. Salinity
2. Water Temperature
3. Water Current
4. Sunlight
All of the above!
This is the property of water responsible for dissolving other polar molecules.
What is adhesion?
This is the principle that proves each biogeochemical cycle we discussed.
What is the Law of Conservation of Matter and Energy?
Another word for all consumers, regardless what level they appear on the trophic pyramid.
What is Heterotroph?
This is the part of a CER response that explains the how the observed phenomenon occurs
What is the reasoning?
Sea ice and glaciers are melting, which of the following would likely be impacted by this phenomenon?
1. Sea levels
2. Arctic animals
3. Migration Patterns
All of the above
During this process, cohesion, adhesion, and surface tension work together to move water through an ecosystem.
What is capillary action?
What is Glucose?
Correctly determine the amount of energy available to the tertiary consumers if the producers have 3400 kcals.
3.4 kcals
What is the charge of oxygen (in water)? What is the charge of hydrogen (in water)?
Oxygen: negative
Hydrogen: positive
