Energy Flow
Where does energy first come into an ecosystem?
The sunlight provides energy to producers
Provide an example of an event that would begin the process secondary succession
Fire, Flooding, Windstorms, Deforestation
How do we identify an atom?
Atomic number (number of protons)
!!!! DAILY DOUBLE !!!!
Who was the scientist that developed the theory of natural selection and what did he first study?
Who is Charles Darwin, and the Galapagos Finches
What 4 things will you find in each cell of the periodic table?
Atomic #, Element Symbol, Element name, Atomic Mass

What is the difference between heterotrophs and autotrophs?
Heterotrophs consume other organisms to gain energy while autotrophs make their own food to gain energy.
How does increased biodiversity result in a more sustainable ecosystem?
A greater variety of species present allows more organisms to adapt after changes occur.
What are the rows and column on the periodic table?
Columns- Groups
What is the difference between natural selection and selective breeding?
Natural selection is when organisms who are better adapted to their environment are able to survive and reproduce
Selective breeding is when two organisms are bred together to produce offspring with more desirable traits.
How many valence electrons and energy shells does 1 atom of Polonium have?
6 valence electrons, and 6 energy shells
What is the difference between a food chain and a food web?
In a food chain, there the flow of energy is only in one direction, in a food web, it is in multiple directions.
!!!!DAILY DOUBLE!!!!
What is a pioneer species and provide an example of one.
The first species to colonize barren environments, examples include lichen, mosses, fungi, bacteria
Increases
How can genetic variation be an advantage to a population?
Name the all subatomic particles, with their charges and locations
Proton- (+) inside nucleus
Neutron- (0) inside nucleus
Electron- (-) outside nucleus
What percent of energy is passed on to the next level in a food pyramid?
What is 10%
Some plants have stems that can hold water and have almost no leaves, which reduces water loss. In which type of habitat would be this important?
Desert
Where can I find the following types of elements of the periodic table? Metals, Nonmetals, and Metalloids
Metals can be found on the left hand side (majority of the elements are metals)
Nonmetals can be found on the right hand side
Metalloids can be found in the staircase pattern in between metals and nonmetals.
Why did the Galapagos finches have different beaks?
They had different food sources available to them.

Carbon
Silicon
Germanium
Lead
Flerovium
Name the first 4 levels in an energy pyramid
Producers, Primary Consumers, Secondary Consumers, Tertiary Consumers
What is the difference between primary and secondary succession?
Primary succession begins with bare rock, secondary succession begins with soil.

This element is most commonly used for cans, window frames, electrical conductors and kitchen supplies. It has 3 energy levels and 3 valence electrons.
What is Aluminum?
!!SKIP TO FIRST PLACE!!
What is an adaptation and how does it occur?
A body part, feature or behavior that helps a living thing survive it happens through natural selection.
This element has 50 neutrons, 2 valence electrons, and 5 energy levels.
