Microscopes
TRUE or FALSE
You can use a live specimen when using the Transmission Electron Microscope (TEM)
FALSE! Because you are using a beam of electrons the specimen cannot be alive.
Solid water becomes ________ dense than liquid water and will float on its surface
Solid water becomes LESS dense than liquid water and will float on its surface
TRUE or FALSE
The use of renewable resources do not cause environmental harm.
FALSE! Clearing of land for solar farms or wind turbines can destroy entire ecosystems.
The maximum population size that can be supported by the available resources in the ecosystem is called....
Carrying Capacity
TRUE or FALSE
Water and carbon cycles have a clear starting and ending point.
FALSE! Both water and carbon cycles are continuous with no starting or ending point.
In which direction does energy flow in the energy pyramid?
Up. From prey to predator. This is represented by arrows within the energy pyramid.
Which TWO microscopes offer a 3D image?
Dissecting microscope and Scanning Electron Microscope (SEM)
__________ is when water bonds to other molecules and _________ is when water molecules bonds to other water molecules.
ADHESION is when water bonds to other molecules and COHESION is when water molecules bonds to other water molecules.
One positive and one negative for use of renewable resources.
Positive- Clean energy- no CO2 emissions; sustainable
Negative- High cost; destroy ecosystems due to land clearing
The last stage of an ecological succession.
Climax community
What are the TWO processes that ABSORB carbon from the atmosphere?
Photosynthesis and Diffusion
Within an energy pyramid diagram, arrows pointing outside the pyramid indicate what?
Energy lost to heat
Which microscope has the lowest magnification?
Dissecting microscope- 40x
When carbon dioxide is taken in by the oceans through the process of diffusion, which property of water supports this?
Universal Solvent
__________ is an energy resource that is not replaced or is replaced very slowly by natural processes. Name TWO examples.
Nonrenewable energy- oil, coal, natural gas
A glacier receded and left behind rocks- what type of succession would occur?
Primary Succession
Chemical process in which a substance reacts rapidly with oxygen and gives off thermal energy with NO flames.,
Combustion
What do we call: an introduced species that has begun to spread rapidly and is causing harm to its new environment.
Invasive Species
What are TWO differences between the Compound Microscope and the Transmission Electron Microscope (TEM)?
Compound- uses light, live specimen, 1000x magnification
TEM- uses electrons, dead specimen, 50,000x magnification
Name ALL four properties of water!
Cohesion
Ability to moderate temperature
Expansion upon freezing
Universal solvent
What happens to the carrying capacity if the non-renewable resources decreases?
The carrying capacity will DECREASE
__________ is individuals leaving a population and ___________ individuals coming into a population.
EMIGRATION is individuals leaving a population and IMMIGRATION is individuals coming into a population.
___________ is when the oceans constantly take in and release carbon dioxide (CO2) with the atmosphere
Diffusion
If biodiversity decreases within an ecosystem, what will happen to the ecosystem?
The ecosystem will become UNSTABLE and WEAKEN or COLLAPSE.
What are TWO similarities between the Dissecting Microscope and the Scanning Electron Microscope (SEM)?
They both give a 3D image of the surface of the specimen
In northern lakes, the surface water freezes during the winter months creating an insulated barrier to keep the water below slightly warmer allowing life to survive. Which water property allows this?
Expansion upon freezing
Two positive and TWO negative for the use of non-renewable resources.
Positive- cheap; infrastructure is already established
Negative- increase carbon emissions; limited supply; global warming
Name TWO biotic and TWO abiotic limiting factors.
Biotic: mates, prey, parasites, humans
Abiotic: water, space, sunlight, minerals, oxygen/carbon dioxide
Name three of the five processes that emit (release) carbon into the atmosphere. Name all 5 for additional points for your team!
Cellular Respiration
Death/ Decomposition
Combustion
Burning
Diffusion
If the producer starts with 1000 KJ of energy how much energy does the secondary consumer receive?
10 KJ of energy
Only 10% of energy transfers from level to level
Primary consumer= 100 KJ
Secondary Consumer - 10 KJ
