10
What is the most SPECIFIC classification category?
Species
10
How does evolution occur?
through NATURAL SELECTION over time.
10
What is the name of the group in the bottom level of a trophic pyramid?
Primary Producers
10
Where do phytoplankton get their energy from?
The sun
20
What continent is the star on? 
The continent of ASIA.
20
If two organisms have almost identical classifications, they share a __________ ___________.
Common ancestor
20
What does survival of the fittest mean?
The individuals most suited to survive in a given environment.
20
Zooplankton is categorized in the ________ level of the trophic pyramid?
Second Level (primary consumers/eat primary producers).
20
What is the size of plankton? (hint: vocabulary term)
Microscopic
30
What is the scientific name for a leopard?
Panthera pardus
30
What is the name of the third classification group?
Phylum
30
What is one evolutionary advantage of skin color?
Protect against skin cancer, absorb vitamin D, protect against UV rays.
30
What is the amount of energy transferred to secondary consumers if there is 200 J of energy at the primary consumer level?
200 J / 10 = 20 J of energy
(10% rule)
30
What type of plankton is this?
Phytoplankton
40
What is marine biology?
The study of life in the ocean.
40
Lions and leopards evolved form the same common ancestor until their _________.
Genus
40
Where would we expect people with darker skin to have trouble absorbing vitamin D?
Far from the equator (up north)
40
Where does the lost energy of as it travels through each level of the pyramid?
It gets released back into the environment as heat.
40
Where can plankton be found?
Near the surface of the water
50
What is the name of the ocean where the star is?
South Atlantic Ocean
50
How can two organisms that share a common ancestor evolve to have different traits? (hint: vocabulary term)
Some traits are better suited to survive in their environment due to EVOLUTIONARY ADVANTAGE.
50
Which classification group shows that humans and cats evolved from a common ancestor with hair and warm blood?
Class - Mammalia
50
What would occur if the number of top predators was drastically reduced?
The number of tertiary consumers would increase which would make the number of secondary consumers decrease.
50
What is the difference between zooplankton and phytoplankton?
Phytoplankton make their own energy (plant). Zooplankton consume other organisms to survive (animal).
