Exam 5

multidiciplinary, mission oriented science focused on protecting biodiversity, ecosystems, and species from rapid, human-driven extinction.

a branch of science concerned with the interrelationship of organisms and their enviorments

community of organisms and their enviorment functioning as a ecological unit

non-native organsism that gorws and disperes quickly and usually to the detriment of native species and ecosystems

rate at which plants and other producers store chemical energy after subtracting the energy used for respiration

a group of interbreeding organisms in a particular location that represents the level of organization at which speciation begins

the rate per unit area or per unit volume at which biomass consumable as food by pother organisms is made by producers

the period of the year that is normally charecterized by a particular kind of weather.

the region in a thermally stratified body of water which seperates warmer surface water from cold deep water and in which temperatures decrease rapidly with depth

state of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness.

the max population than an area will support without undergoing deterioration

most common spatial dispersion in nature, where individuals in a population are grouped in patches, usually around essential resources, social interaction, or patchy habitats.

biological influences that affect population groth rates based on population density

enviormental, abiotic, or physical factors- such as weather, natural disasters, and pollution- that affect population size regardless of how dense the population is.

spatial arrangemnet of individuals within a populations habitat

departing from a place, natural home, or residence to reside elseware

sequence of age- or stage specific events related to an organisms growth, development, reproduction, and survival from birth to death.

any resource or enviormental condition that restricts the growth, abundance, or distribution of an organsims or a population within a ecosystem.

a model of population groth that occus when resources are limited, causing the growth rate to slow as the population size approacges its maximum sustainable level (carrying capacity)

net change in a populations size per individual over a specific time period

calculated as the birth rate (b) minus the death rate (d) oer individual. defines how fast a population grows or declines

subfield of biology that studies how and why the size, density, and structure of a specific species population in a given geographic area change over time

the average number of individuals of a species per unit area or volume, measuring how crowded a population is within its habitat.

a pattern where individuals are spaced at unpredictable distances from one another, with no specifc, predictable pattern to their location.

line graphs illustrating the proportion of a population surviving at each age, used to analyze mortality rateds, ;ife expectancy, and reproductive stratagies.

spatial arrangement where individuals in a population are soaced more or less equally apart, resulting in a even, regular distribution across their habitat.

organisms that thrive in unstable or unpredictable enviorments by prioritizing high reproductive rates over competetive ability ( stands for growth rate)

a life history stratagy in biology where species thrive in stable enviorments by producing fewer, larger offspring with high parental care, enabling them to live near the carrying capacity.

Relationship in which one benefits from the other without benifiting or harming it

a interacting population of various kinds of individuals (species) in a common location

an interaction between organisms or species striving for the same limited resources

temporary abrupt change in enviormental conditions that significantly alters ecosystem structure, biomass, or resource availability.

relationships vetween organisms in an ecosystem, spanning from the same species (intraspecific) to different species (interspecific).

hierarchical sequence of organisms showing how energy and nutrients transfer through and ecosystem.

interconnected netweorj of multiple food chains showing how energy and nutrients flow through and ecosystem, illustrating who eats whom

full range of enviormental conditions, resources, and habitats a species can theoretically occupy and utilize in the absense of biotic limitations like competition or predetors

individuals of different species compete for the same limited resources such as food water or space in a ecosystem

individuals of different species compete for the same limited resources in a ecosystem

organism that holds and ecosystem together, playing a critical role in structure, stability, and biodiversity, despite often having low population numbers.

a symbiotic relationship where bpoth organisms benifit and depend on eachother

the specific role and profession of a species within its ecosystem

competing species adapt to utilize different resources, habitats, or behaviors to minimize competition to coexist

one organism hunts, klills, and consumes another organism

process by which organisms colonize a barren enviorment, leading to the formation of a new ecosystem over time

ecological succession that follows after a primary succession

variaty and relative abundance of different species within a given area or ecosystem

total count of different species within a specific community, landscape, or region.
