snake, falcon, mountain lion
100
What is the ultimate source of energy?
the sun
100
Who was the father of evolution?
Charles Darwin
100
the process that the youngest layer of soil is on the top of the ground and the oldest is at the bottom is known as what law?
law of superposition
200
water and sunlight would be examples of what kind of factor?
abiotic
200
How are predators and prey related to population size? (think of the chart)
When the prey population increases so does the predator population then the prey population will decrease (they are all getting eaten) and the predator pop will decrease because they no longer have any food
200
what is the first level of a food chain
a producer or a plant
200
What is the concept that over time organisms change due to their environment?
evolution
200
True or False: Every living organisms has been observed through fossils
false
300
Which is the correct order of an ecosystems hierarchal structure? A. species, populations, organisms, communities, biosphere, ecosystem B. organisms, species, populations, communities, ecosystem, biosphere C. organisms, populations, species, communities, ecosystem, biosphere
B

Which is an apex predator? A. Great white shark B. Lion C. Humans
all of the above
300
a caterpillar is an example of: A. producer B. primary consumer C. Carnivore
primary consumer
300
what is it called when random genetic modifications occur and the mutation benefits an organisms and over time that beneficial mutation is passed down?
natural selection
300
Where did Charles Darwin visit that led him to create the theory of evolution?
Galápagos Islands
400
What kind of population does a density dependent factor effect?
large populations
400
True or False: Competition between species does not occur when a species has a niche
true
400
Which level of an energy pyramid can support the least organisms?
the top of the pyramid
400
What is plate tectonic theory?
the process responsible for changes that we observe today are similar to the processes that have occurred throughout Earth's History
400
True or False: in a stable environment, populations can change at a predictable rate
true
500
When will a change in an environmental factor decrease the size of a population?
When its ability to survive is decreased by the change in factor
500
Out of the following symbiotic relationships (parasitism, mutualism, and commensalism) which is when neither organism is affected by the other
commensalism
500
How is a biomass pyramid different than a numbers pyramid?
a biomass pyramid includes alive and recently alive matter
