Cards

Term
How are biomes classified?
Definition
Climate and Rainfall (precipitation)
Term
What is Primary Succession?
Definition
Rock-->Lichens-->Moss/Ferns-->Bushes/Small Trees-->Bigger Trees-->Climax Community
Term
What is a Climax Community?
Definition
An environment where little to no change happens.
Term
What's the difference between Primary and Secondary Succession?
Definition
Primary starts with only rocks, no soil.
Secondary starts with soil, no vegetation
Term
What happens to the 90% of the energy that is not used in the next level by an organism?
Definition
It is:
Lost to heat
Used for growth and reproduction
Waste that is not edible
Term
How much energy moves from one level to the next in the Energy Pyramid?
Definition
10%
Term
To express the energy passed to the energy level above it should the decimal be moved to the right, or left?
Definition
Left
Term
To express the energy passed to the energy level below it should the decimal be moved to the right, or left?
Definition
Right
Term
What is Secondary Succession?
Definition
Secondary Succession occurs after an abrupt change such as fire, volcanic eruption, or deforestation when plant and tree life is wiped out.
Term
Does Primary Succession occur more rapidly than Secondary Succession?
Definition
No. Secondary Succession is much more rapid because soil and possibly seed and/or plant remnants may remain.
Term
What is the Energy Pyramid term for organisms that can do photosynthesis?
Definition
Producers
Term
What are Primary Consumers?
Definition
Plant eaters (herbivores)
Term
What are Secondary Consumers?
Definition
Meat eaters (carnivores)
Term
What are Omnivores?
Definition
Consumers who eat both plants and other animals. Humans are omnivores and NOT part of the Energy Pyramid.
Term
Which level is at the bottom of the Energy Pyramid?
Definition
Plants
Term
If bugs are removed from this food chain what will happen to the other 3 groups
Plant-->Bugs-->Shrew-->Hawk
Definition
Plants will increase
Shrews will decrease
Hawks will decrease
Term
What is the driving force for the Water Cycle?
Definition
The sun
Term
How does water get into the atmosphere?
Definition
Evaporation and evapotranspiration.
Term
Why do we need water?
Definition
Photosynthesis! It's a large portion of our cells/body. No water, no life
Term
Why is Carbon needed?
Definition
Needed to make sugars, fats, proteins and nucleic acids. Also provides heat and power.
Term
What is the driving force of the Carbon Cycle?
Definition
Sun
Term
How do we get Carbon out of the atmosphere?
Definition
Photosynthesis
Term
How does Carbon get into the atmosphere?
Definition
Respiration and combustion
Term
What is the driving force of the Nitrogen Cycle?
Definition
Bacteria
Term
Why is Nitrogen important?
Definition
To make nucleic acids (DNA/RNA/ATP) and proteins
Term
How does Phosphorous get into the atmosphere?
Definition
It doesn't
Term
Where is Phosphorous found?
Definition
Rocks and living things
Term
What other cycle is the Phosphorous Cycle similar to?
Definition
Rock Cycle
Term
Why do we need phosphorous?
Definition
Nucleic acids (DNA/RNA/ATP) and phospholipids (cell membrane)
Term
Arrows in a Food Chain show:
Definition
Flow of energy
Term
What makes the Nitrogen Cycle different?
Definition
It uses bacteria and lightning.
Term
Succession is what?
Definition
Smaller plants grow leaving behind soil for bigger plants to grow.
