exponential growth equation

Front

dN/dt=rN

Back

conditions that favor exponential growth

Front

continuous supply of resources reduced predation, disease, parasitism positive birth rate little to no competition colonization

Back

exponential growth graph

Front

Exponential growth graphs curve up

Back

mutualism

Front

(+,+) Both organisms benefit

Back

where does Co2 enter in plants?

Front

the leaves!

Back

primary production

Front

total amount of carbon fixed by photosynthesis

Back

dispersion

Front

how organisms are distributed in space, can either be clumped, uniform, or random

Back

population ecology

Front

The study of populations in relation to the environment, including environmental influences on population density and distribution, age structure, and variations in population size.

Back

density dependent model

Front

logistic growth

Back

commensalism

Front

(+,o) One organism benefits and the other isn't affected

Back

predation

Front

(+/-) An interaction in which one organism kills another for food.

Back

random distribution

Front

spreading seeds throughout the wind, random dispersal

Back

clumped distribution

Front

predator defense, clumped distribution of resources, protection from environment and cold

Back

density

Front

#/area

Back

carbon cycle

Front

The organic circulation of carbon from the atmosphere into organisms and back again

Back

uniform distribution

Front

limited resources leading to equal distribution, territoriality, aggression

Back

demography

Front

average characteristics of members of populations

Back

logistic growth graph

Front

S-shaped curve

Back

biotic components

Front

living organisms of ecosystem

Back

community ecology

Front

the study of interactions between species

Back

dynamics

Front

how population changes over time (equations)

Back

competition

Front

(-/-) two species are interacting and neither is benefiting from the interaction going after the same resources

Back

population descriptors

Front

density dispersion demography dynamics

Back

ecosystem ecology

Front

emphasizes energy flow and chemical cycling among the various biotic and abiotic components

Back

parasitism

Front

(+/-) A relationship between two organisms of different species where one benefits and the other is harmed requires host

Back

net primary production

Front

the total energy and matter available to trophic levels above it

Back

ecology

Front

the study of interactions

Back

logistic growth equation

Front

dN/dt=rN(K-N/K)

Back

energy flow

Front

The passage of energy through the components of an ecosystem

Back

density independent model

Front

exponential growth

Back

abiotic components

Front

nonliving players in an ecosystem

Back

producers

Front

Organisms that make their own food (Photosynthesize)

Back

population estimation equation

Front

Nt = N0e^rt

Back

what could cause r to change?

Front

famine disease harsh winter inbreeding climate change predation
