• MORBIDITY General term meaning the occurrence of disease and illness in a population.
• POPULATION entire group of people of different races, sexuality, and status; objects like material things; events like social gatherings; hospital or school visitations, and measurements of a distinct boundary.
• DEMOGRAPHIC TRANSITION the shift in the history of birth and death rates in society because of the absence of science and technology advancements
• POPULATION DENSITY frequently applied to living organisms, most of the time, to humans and  a key geographical term
• MORTALITY RATE the number of death in a given population over some time
• SEX RATIO ratio of males to females in a population. In most sexually reproducing species, the rate tends to be.
• FECUNDITY

  Referred in two ways a. human demography has the potential for the reproduction of a listed population as opposed to a single organism. b. For the study in the biological community, it is similar to fertility, wherein it is a natural way to produce offspring.
• DEMOGRAPHY

  The statistical features of the human population.

   

  The demographic analysis can cover whole societies or groups comprising education, nationality, religion, and ethnicity.
• MIGRATION

  movement of people of different sectors from one country to another with the intention of the new location, new work or employer or for greener pasture.

  The movement is often over long distances and from one country to another, but internal migration within the city is also possible; indeed, this is the dominant form globally.
• DEMOGRAPHY

  field of science interested in collecting         and analyzing demographic parameters 

  •  study of characteristic of population
• DEMOGRAPHIC PARAMETERS

  series of statistical measures to study      populations objectively

  •  population size, density, age structure,      fecundity, mortality and sex ratio
• POPULATION GROWTH

  The rise in the number of people on Earth 

  It is typically measured as a percentage increase in the population size over a set period, such as a year, and can be influenced by factors such as birth rates, death rates, immigration, and emigration

  Sustainable management of population growth is an important consideration for governments and policymakers to ensure the well-being and quality of life for their citizens.
• 2 Primary Components of Population Growth

  1. natural increase
  2. net migration
• NATURAL INCREASE

  Is the difference between the number of births and the number of deaths in a population over a specific period.
• NET MIGRATION

  Accounts for the difference between the number of people moving into a region (immigration) and the number of people leaving the region (emigration). 
• TAXONOMY is the practice and science of categorization or

  classification.
• vast variety of life on Earth is referred to as BIODIVERSITY
• HOTSPOTS are also home

  to endemic species, which can only be found in a single place.
• TAXONOMY the branch of biology that classifies all living things
• TAXON plural: (taxa) is a group of organisms that are classified as a unit. This can be

  specific or general.
• BIODIVERSITY different kinds of life you’ll find in one area—

  the variety of animals, plants, fungi, and even microorganisms like bacteria that

  make up our natural world.
• FERTILITY refers to the capacity to become pregnant or to have children.
• FAMILY

  A taxonomic rank is more specific than order but less specific than genus?
• BIRTH RATE EXPECTANCY

  refers to the average number of years a newborn infant can expect to live births.
• DEMOGRAPHIC TRANSITION

  three-stage pattern of change in birth rates and death rates that

  has occurred during the process of industrial and economic development.
• DOMAIN

  It is the highest (most general) rank of organisms.
• PREDATION

  is referring to a biological interaction where one organism captures

  and kills other organisms, its prey.
• SYMBIOTIC RELATIONSHIP

  referring to any close and long-term biological

  interaction between two different organisms.
• MUTUALISM both

  organisms benefit from each other.
• PARASITISM symbiotic relationship between species, where one organism, the

  parasite, lives on or in another organism, the host, causing it some harm, and is

  adapted structurally to this way of life.
• KEYSTONE SPECIES

  a concept that was introduced by Robert T. Paine in

  1969. It pertains to species relative to its abundance is a disproportionate effect on its natural environment
• A species' way of making a living is

  called its NICHE
• organism’s HABITAT is where it

  lives.
• COMPETITION

  relationship between organisms that strive for the same

  resources in the same place. The resources might be food, water, or space.
• 2 types of competitio:

  1. INTRASPECIFIC COMPETITION -same species
  2. INTERSPECIFIC COMPETITION - different species
• GENUS

  group of similar species
• CLASS

  the most general rank in the taxonomic hierarchy until phylum was introduced
• PHYLUM

  next level of classification and is more specific than kingdom
• KINGDOM

  highest level of classification next to domain
• ORDER

  more specific than class and constitutes one or more than one similar families
