Cells make tissues, tissues make organs and organs make . . .
What is systems?
100
This type of heat transfer occurs in the mantle.
What is convection?
100
Solar, wind, water/hydro, geothermal and biomass are all examples of this.
What are renewable resources?
100
These are in the bottom of the energy pyramid because most of the energy in an energy pyramid is used or lost as heat energy as it moves up the pyramid.
What are producers?
100
The smallest unit of life.
What are cells?
200
These are the basic unit of structure and function in all living things.
What are cells?
200
D=M/V is the equation for hot fluid rising and cold fluid sinking.
What is density?
200
Nuclear/uranium, propane, petroleum, natural gas and coal are examples of these.
What are nonrenewable resources?
200
This is how humans mostly impact the environment.
What is habitat destruction?
200
Heat transfer through empty space.
What is radiation?
300
These four systems are used when you brush your teeth.
What is digestive, skeletal, muscular and nervous?
300
This is heat transfer through direct contact.
What is conduction?
300
Lack of education, poor nutrition and disease are all caused by this.
What is water inequality?
300
The scientific way of saying a population went up then down.
What is increasing then decreasing?
300
Subduction causes these.
What is a trench?
400
This is what it's called when your temperature, stress, nutrition, and fitness level are all balanced.
What is homeostasis?
400
This type of boundary is occurring when one plate is subducting under another.
What is a convergent plate boundary?
400
The same water is cycled over and over on earth because of this.
What is the water cycle?
400
Illness, migration, and hunting are all reasons for a population to do this.
What is decrease?
400
These are on the bottom of the energy pyramid because they hold the most energy.
What are producers?
500
A group of parts that work together.
What is a system?
500
This crust is less dense then oceanic crust.
What is continental crust?
500
Materials found in nature that people use as raw materials for their survival and comfort.
