Experiments
Changing things up
Surviving and Thriving
Ecosystems and Energy
Ecosystem Structure
100
The variable that you are measuring as a result of your experiment
Dependent Variable
100
This is a change in the DNA (genetic information) of an organism
Mutation
100
This series of letters will help you remember how evolution occurs
VISTA
100
Organisms that can make their own food via photosynthesis
Autotrophs
100
The number of animals that can be sustainably supported by an ecosystem
Carrying Capacity
200
Something that stays the same each time you do the experiment
Constant
200
This is any difference in physical characteristics among member of the same species
Variation
200
When bacteria are exposed to an antibiotic they are experiencing a ________ _________
Selective Pressure
200
These are the organisms that form the base of the trophic levels by harnessing the energy from the sun
Producers
200
This will happen when a population of animals reproduces too much and uses up all of its resources
Die-off
300
The variable that you are choosing to test/change in an experiment
Independent variable
300
White mice blend in better to sand and black mice blend in better to dark lava rocks. This is an example of __________
Adaptation
300
This is the process where a random mutation in one organism helps it survive a selective pressure, it can pass on it's adaptive genes so that future generations with this adaptation will be more likely to survive
Natural Selection
300
Animals that eat plants are found in the trophic level we call
Primary Consumers
300
This is an organism whose presence helps an ecosystem remain stable with high biodiversity
Keystone species
400
The independent variable in this study:
Amount of antibiotic
400
Organisms who have an advantage are more likely to _________.
Survive and reproduce
400
When offspring receive adaptive genes in the DNA from their parents it is called ________
Inheritance
400
In a food web, arrows point in the direction that _______ moves
Energy
400
When a keystone species is removed it causes a direct effect on the ecosystem which then has a series of additional indirect effects
Trophic cascade
500
The dependent variable in this experiment:
Size of the Zone of Inhibition
500
Mutations occur during this process
Reproduction
500
People will mistakenly believe that this is a part of evolution. If it was, we would say LAVIST instead of VISTA
Learning
500
According to this rule, 90% of the energy from one trophic level will be lost as heat to the environment
Rule of 10%
500
This theory surprised scientists when they observed that predators who eat other animals actually help keep plant populations stable
Green World Hypothesis
