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 

  • Overproduction. Most species produce more offspring than can survive.
  • Competition. Since living space and food are limited, organisms must compete for the necessities.
  • Variation. Differences between individuals in a population.
  • Adaptations. ...
  • Natural selection. ...
  • Speciation.

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.

200

Behavioral isolation 

 when species are reproductively isolated from others due to differences in behavior.

200

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.

Hierarchical levels of classification 

species, genus, family, order, class ,phylum, kingdom, domain.

Its J curved 

exponential

What's symbiosis

 a close, prolonged association between two or more different biological species.

400

What is qualitative data

 data representing information and concepts that are not represented by numbers.

400

temporal isolation 


Temporal isolation happens when two or more species reproduce at different times.

400

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.

500

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.
