What is ecology?
Ecology is the study of biotic and abiotic factors of an ecosystem and the interactions between them.
Name four abiotic factors found in a prairie ecosystem.
Sunlight, Soil, Temperature, Oxygen, Water
Name three populations found in a prairie ecosystem.
Prairie Dogs, Burrowing Owls, Rattle Snakes
Show the levels of organization in an ecosystem. Start with the smallest unit.

An environment that provides the things that a specific organism needs to live, grow, and reproduce is its (fill in the blank).
All the living and nonliving things that interact in a particular area make up a(n) (fill in the blank).
The parts of an organism's environment that are living or once living, and interact with the organisms are (fill in the blank).
All the different populations that live together in an area make up a(n) (fill in the blank).
What is an example of what lives in a prairie ecosystem?
What is an example of what a biotic factor?
Write a list that lists the levels of an ecosystem in order from largest to smallest?
ecosystem, community, population, organism
An organism gets food, water, shelter, and other things it needs to live grow and reproduce from (fill in the blank).
True or False (if false state what is false): The nonliving things that interact with an organism are called biotic factors.
False, change biotic factors to abiotic factors
True or False (if false state what is false): The study of how living things interact with each other and their environment is called ecology.
True or False (if false state what is false): A group of organisms that can mate with each other and produce offspring are called a species.
True or False (if false state what is false): Oxygen is an abiotic factor in the environment that is important for plants to make their own food.
False, oxygen is changed to sunlight or water
True or False (if false state what is false): All the organisms that live in a particular area and their nonliving make up an ecosystem.
True or False (if false state what is false): All the members of one community living in a particular area make up a population.
False, change community to species
An organism is a living thing.
All living things and non-living things that interact.
An environment that provides the things a specific organism needs to live, grow, and reproduce.
The parts of a habitat that are living, or once, and interact with an organism.
The non-living parts of an organism's habitat.
These organisms use the sun's energy to turn water and carbon dioxide into food molecules.
A group of organisms that can mate with each other and produce offspring that can also mate and reproduce.
All the members of one species living in a particular area.
All the different populations that live together in an area.
How organisms interact with each other and their environment.
What are the five abiotic factors?
Water, Oxygen, Temperature, Soil, Sunlight
The number of individuals in an area of a specific size.
An informed guess.
The number of births per 1,000 individuals for a given time period.
The number of deaths per 1,000 individuals for a given time period.
Leaving a population.
Moving into a population.
Environmental factor that causes a population to stop growing or decrease in size.
The largest population that an area can support.
What are the 4 ways changes occur in population size?
Immigration, Emigration, Deaths, Births
What are the 3 limiting factors?
Space, Food and Water, Weather Conditions
The process by which organisms that are best adapted to their environments are most likely to survive and reproduce.
An inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment.
How an organism makes its living and interacts with the biotic and abiotic factors in its habitat.
The struggle between organisms to survive as they attempt to use the same limited resources at the same time.
An interaction in which one organism kills another for food or nutrients.
The organism that does the killing in a predation interaction.
An organism that is killed and eaten by another organism in a predation interaction.
The organism that benefits by living with, in, or on a host in a parasitism interaction.
An organism that a parasite lives with, in, or on, and provides a sources of energy or a suitable environment for the parasite to live.
