The study of living organisms, divided into many specailized fields.
Define biology.
100
Keeping animals in a classification system helps make things easier to find and understand
why is a classification system so important?
100
biotic is living and abiotic is nonliving
examples
biotic-dog
abiotic-weather
What is the difference between abiotic and biotic? Give examples.
100
Natality: birth rate
Mortality: death rate
Emigration: number of individuals moving away
Immigration: number of individuals moving in
Describe characteristics of populations.

Decomposers break down plants and animals, without these plants wouldn't get enough nutrients.
What are decomposers?
200
It’s a universal measuring system so two people can measure and compare things and get the same results based on the power of 10
What is the importance of the metric system?
200
Plants: herbs, shrubs, and trees
Animals: land, water, air
What are the specific divisions within the classification system?
200
Habitat: The natural home or environment of an animal, plant, or other organism
Niche: the position or function of an organism in a community of plants and animals
Differentiate between an organism’s habitat and its niche.
200
Carrying capacity: the max number of individuals in a species that an environment can support for the long term
What is carrying capacity?
200
An electron is a subatomic particle with a negative charge.
What is an electron?
300
Observation: something you see that isn’t proven with data and could possibly be false
Inference: something you believe will happen based on previous evidence
What is the difference between an observation and an inference?
300
Behavior, morphological, and evolutionary relationships in their classification systems
Give examples of abiotic and bitotic things that would affect a species.
300
keep a population from continuing to increase indefinitely
What does a limiting factor do?
300
An atom or molecule that binds together with other monomers to create polymers.
What is a monomer?
400
Control: the thing that stays the same that you use to compare against others
Independent variable: the variable you change
Dependent variable: results from or depends on changes to the independent variable
Differentiate among control, independent variable, and dependent variable.
400
Binomial nomenclature- A species name gets a genus which is the first part name and the second part is the specific epithet or specific name that identifies the species.
How do scientists name organisms?
400
The arrows go wherever the energy is going. So when a hawk eats a mouse the arrow is pointing towards the hawk because the hawk is getting energy from the mouse.
Describe the flow of energy through an ecosystem.
400
not enough food, water, and shelter
What are the consequences of having too big of a growing population?
400
A type of diffusion where organisms exhibit a clumped dispersion when they are found in groups.
What is clumped dispersion?
500
Adaptations evolve, maintains homeostasis, made of one or more cells, display organisms, grows and developes, reproduces, requires energy, responds to stimuli
What are the characteristics of all living things?
500
Made of one or more cells, displays organization, grows and develops, reproduces, responds to stimuli, requires energy, adaptations evolve over time, and maintains homeostasis.
What basic criteria should a classification system meet?
500
Biosphere: part of earth that contains all ecosystems
Ecosystem: community and its nonliving surroundings
Community: populations that live together in a defined area
Population: group of organisms of one type that live in the same area
Organism: individual living thing
Groups of Cells: tissues, organs, and organ systems
Cells: smallest functional unit of life
Molecules: groups of atoms; smallest unit of most chemical compounds
Describe the levels of biological organization.
500
Biotic relationships such as predator/prey, symbiosis, and competition
What determines population size?
500
A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms.
