Quick Vocab
100
Pavlov's dog is an example of
Classical conditioning
100
The two ways populations grow
exponentially and logistically
100
Describe the energy flow of nutrients
100
The study of interactions between single populations and communities
Ecology
200
Describe how a scientist can determine if behavior is from genetic or environmental factors?
Think of the snake example from class: Two snakes from two environments breed in a lab. The babies are tested for food preference and find that one population is more interested in the food. This shows that the behavior is innate.
200
Survivorship curve: most individuals die young
Type III

What is the difference between a food chain and food web?
Food Chain: single path of energy flow
ex: leaves->bugs->sparrow->hawk
food Web: interconnecting paths of energy flow
200
require only inorganic nutrients and outside energy source to produce organic nutrition. Provides energy for themselves and members of the community
Autotrophs
300
A baby duckling sees a dog when she first hatches. She then proceeds to follow the dog around at all times.
Imprinting
300
What is the difference between a population and community?
Population: group organisms same species occupying certain area and sharing gene pool
Communities:Assembly of species interacting with one another
300
The reason why few carnivores can be supported in a food web
10% rule: as you move up an ecological pyramid, 10% of energy is available at the next trophic level. Since carnivores are at the top, there is the least amount of energy available to them.
300
consumers that take in organic food. These can be further classified as omnivores, herbivores, and carnivores
Heterotrophs
400
Training a dog to run through agility trials in an example of
operant conditioning
400
Why do prions (CWD) last a long time in an environment?
They are proteins, and protein cannot be destroyed easily by heat or UV light. Therefore, they are in an environment for a long time and are passed through urine or corpses of deer.
400
Pathways where chemicals circulate through biotic and geological components
Biogeochemical cycle
400
heterotrophic bacteria that breakdown nonliving organic matter and release inorganic nutrients that are taken back up by plants
Decomposer
500
When is monogamy common
males limited mating opportunities
territoriality
male certain offspring are his
500
What are the three models of succession?
climax-pattern: particular areas always lead to same type of community(climate and biome)
facilitation model: some communtiy members prepare landscape for new species
tolerance model:different types plants colonize at same time
500
CO2, methane (CH4), Nitrous Oxide (NO2), hydrofluorocarbons
greenhouse gases
500
Establishment of plant community in newly formed area where no soil composition
primary succession
