scientific study btwn organism and the environment
how can abiotic or biotic environments be classified as?
-resources and conditions
what are resources?
they can be consumed
what are conditions?
they influence an organism but cannot be consumed
how do resources or conditions affect competition?
resources make it more competitive while conditions alter the conditions for the competitiveness
what is “oikos” greek
means household (of nature)
what is biogeography?
where similar organisms (plants) occur in similar climates

(relates envy with species distribution)

what is an ecosystem?
the ability of species to survive in a a specific environment
what does an ecosystem include?
a biotic and abiotic community?
what is a network”ecosystem”?
it includes bot abiotic and biotic interactions that function as as one
what is a biotic environment?
they are living interactions.
like everything that has cells

what is an observational study?
it’s a measurement of an independent and dependent variable.
response- dependent
what is a field experiment?
what are some cons/ pros?
it’ an experiment that is performed in nature
cons- difficult to control factors
pro- they are realistic
why do we need replication?
to achieve accurateness and cosinstency in your results
acts as a control which is a good comparison
what is statistical population?
involve collecting data and drawing conclusions
-aka the measurements of ecological studies
what is the sample?
is that part that is observed!!
what are the two types of data you could have?
define them?
-categorical- qualitative
-numerical- quantitative (continous)
what is categorical data? give examples
hair colour, sex
what are the two values for numerical data? explain
-Discrete (whole numbers,
-continous data (any value within an interval, 0.5, height, weight
what is a histogram?
where are they placed
the relationship between categorical variable and continuous variable.
categorical- the x-axis, explanatory, independent
numerical- y axis, response, dependent
what is a scatter plot?
the relationship between two independent/ continuos variables or sets of observations
what is a scatter plot?
the relationship between two independent/ continuos variables or sets of observations
