Population Properties and Dynamics
The movement of individuals into the population, and the movement of an individual out of the population
Immigration and Emigration
Long term strategy to enter a state of reduced activity
Dormancy
Get energy from eating other organisms or organic waste/heterotrophs
Ex: Herbivore, Carnivore, Omnivore
Consumer
Predator eats part or all of an individual of another species
Predation
Birth rate
Natality Rate
Distribution of individuals among different ages in a population
Age structure
Organisms that don't regulate their internal conditions and organisms that use energy to control some of their internal conditions
Conformers and Regulators
Organism's position in a sequence of energy transfers
Trophic Levels
Close long-term relationship between two organisms
Symbiosis
Death Rate
Mortality Rate
Mortality data of different species, the probability that members of a population will live till a certain age
Survivorship
Non-living and living things that affect the environment
Abiotic and Biotic Factors
Single pathway of feeding relationships among organisms and many food chains interlink, a diagram that resembles a web
Food chain and food web
Members of the same species compete for limited resources, and two or more species use the same resources
Interspecific and intraspecific Competition
Number of individuals that the environment can support for long periods of time
Carry Capacity
Observation that population can grow in a pattern
Exponential Model
Process where some organisms can adjust their tolerance to abiotic factors
Acclimation
Eats plants, eats animals, eats everything
Herbivore, Carnivore, Omnivore
One species is eliminated from a community because of competition for limited resources
Competitive Exclusion
Birth rates and death rates are not constant but vary with population size; birth rate declines and death rates rise as the population grows, and the opposite is true
Logistic Model
Restrains growth of population
Limiting Factors
Specific role of a species within its environment, and a place where an organism lives
Niche and Habitat
Consumers that feed on the garbage of an ecosystem, and many bacteria and fungi that cause decay by breaking down complex molecules
Detritivore, Scavenger/Decomposer
Chemicals that are often byproducts of the plant's metabolism, Bad taste, poison, or irritation
Secondary Compounds
Reduces population by the same portion regardless of its size and individual's chance of survival or reproduction depends on number of individuals in the same area
Density Independent and Dependent Factors
