Unit 1
What is a independent variable
a variable that stands alone and isn't changed by the other variables you are trying to measure.
Darwin's 6 points of evolution
Whats a population
Members of the same species that live and interbreed with one another in the same habitat.
Name 5 of the trophic levels
producer, primary consumer, secondary consumer, and tertiary consumer
What is a dependent variable
the variable that changes as a result of the independent variable manipulation.
Behavioral isolation
when species are reproductively isolated from others due to differences in behavior.
The 2 different types of growth curves.
Exponential and logistic
Explain primary and secondary succession
Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is made of rock, devoid of soil.
How is a hypothesis statement written
Using if.. then.. format
Hierarchical levels of classification
species, genus, family, order, class ,phylum, kingdom, domain.
Its J curved
exponential
a close, prolonged association between two or more different biological species.
What is qualitative data
data representing information and concepts that are not represented by numbers.
temporal isolation
Temporal isolation happens when two or more species reproduce at different times.
Its S curved
Logistic
What's the difference between abiotic and biotic
Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
What is an inference
an idea or conclusion that's drawn from evidence and reasoning.
list all the types of isolation
behavioral, Temporal, reproductive, and geographic
How is logistic and exponential different
Exponential growth presumes infinite resources, resulting in unrestrained population expansion. Conversely, logistic growth considers resource limitations and a carrying capacity
What's the difference between an food web and food chain
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem.
