Birth rate and death rate are number of births or deaths per 1,000 individuals for a given time period.
What is birth rate and death rate?
100
The behaviors and physical characteristics that allow organisms to live successfully in their environment.
What are adaptations?
100
The series of predictable changes that occur in a community over time.
What is succession?
100
Biotic and Abiotic factors
What is makes up a habitat?
200
An environment that provides the things a specific organism needs to live, grow, and reproduce.
What is a habitat?
200
Immigration means moving into the population and emigration means leaving the population.
What is the difference between immigration and emigration?
200
Individuals whose unique characteristics are well-suited for an environment tend to survive and produce more offspring. Offspring that inherit these characteristics also live to reproduce. In this way, natural selection results in adaptations.
How does natural selection work?

Primary succession is the series of changes that occurs in an area where no soil or organisms exist. (BONUS: the first species to populate an area are called pioneer species.) Secondary succession is the series of changes that occurs in an area where the ecosystem has been disturbed, but where the soil and organisms still exist.
What is the difference between primary and secondary succession?
200
size, leave
Population can change in ________ when new members join the population or when members ________ the population.
300
Biotic factors are the living, or once living, and interact with an organism. Abiotic factors are the nonliving parts of an organism's habitat.
What is the difference between biotic factors and abiotic factors?
300
The number of individuals in an area of a specific size. Population density can be written as an equation: Population density= Number of individuals/ Unit area
What is population density?
300
Competition and predation
What are the two major types of interactions among organisms?
300
The first species to populate an area
What are pioneer species?
300
Mutualism, commensalism, or parasitism
(Example depends on what you choose and will be determined by the teacher)
Name a type of symbiosis and give an example of it. (Teacher will determine if it is correct)
400
The study of how organisms interact with each other and with their environment.
What is ecology?
400
An environmental factor that causes a population to stop growing or decrease in size. Four limiting factors are weather conditions, space, food, and water.
What are limiting factors? Name four limiting factors.
400
A predator is the organism that does the killing and the prey is the organism that is killed.
What is the difference between a predator and prey?
400
Fires, hurricanes, and tornadoes. Human activities, such as farming, logging, or mining, may also disturb an ecosystem and cause secondary succession to begin.
What are some natural disturbances that effect secondary succession?
400
Primary, secondary
Unlike _________ succession, __________ succession occurs in a place where an ecosystem currently exists.
500
It starts out as an organism, a single prairie dog, then it becomes a population with a town of prairie dogs, next it becomes a community where all the living things on the prairie interact, and finally it becomes an ecosystem in which all the living and nonliving things interact on the prairie.
How is an organism's ecosystem organized?
(Example of an animal: a prairie dog)

21 llamas
Suppose a population of 8 llamas have produced 20 young in a year. If 7 llamas have died, how many llamas are in the population now? (Assume no llamas have moved into or out of the population for other reasons.)

Mutualism: a relationship in which both species benefit.
Commensalism: a relationship in which one species benefits and the other species is neither helped nor harmed.
Parasitism: a relationship that involves one organism living with, on, or inside another organism and harming it. (The organism that benefits is called a parasite.)
What are the three types of symbiosis? Tell me the definition of each one.
500
Volcanic Eruption: shortly after a volcanic eruption, there is no soil, only ash and rock. Pioneer Species: the first species to grow are pioneer species such as mosses and lichens. Soil Creation: as pioneer species grow and die, soil forms. Some plants grow in this new soil. Fertile Soil and Maturing Plants: as more plants die, they decompose and make the soil more fertile. New plants grow and existing plants mature in the fertile soil.
What is the order in which primary succession occurs in an area where no soil and no organisms exist?
500
Primary succession because there was no existing soil or organisms to start with and a volcanic eruption occurred.
Lichens and mosses have just begun to grow on a rocky area where a volcanic eruption has happened. What type of succession is occurring? Explain.
