Technology
Application of scientific knowledge for any invention
ecologist and biologist
People who study the environment and collect data about the population size in dif environments
Global positioning system
GPS
phenomenon
a situation that i exists especially one that causes or is an explanation to questions
GPS
they are used to track patterns of different species
stakeholders
land developers,local gov., or conservation groups
scientific method
Its when you ask questions,make a prediction and make experiment(s) to answer question(s)
Engineering design proces
The process of iterations till you get a solution to your question(s)
Environmental impact
What benefits and non benefits does it have
Decision matrix
A easy way to pick best solution
Input
what goes into a system
output
what goes out of a system
Input system
Both input output flows freely it contains energy and matter
output system
input can flows and output is limited only energy is exchanged
Isolated systems
Both input output or contained like an ice cooler
input/output
Are energy,matter,information
manuel
is a type control
automatic
is a type control
automatic and manuel
is a mix of both controls
Feedback loop
when its of cycle and input leads to out put and output leads to input
population density
how many individuals living in a given space
large picture
emergent property it is a large unit
geosphere
the earth its self
hydrosphere
All body of water in earth
anthrosphere
Man made stuff
Biotic factors
living/once living componets
abiotic factors
non-living componets(energy and matter)
ecosystem levels smallest to bigggest
Organisms,population,community,ecosystem,biome, biosphere
biotic ecosystem
29% land based 71% water based
Mantaining homostasis
Mantaining stable internal condition
A ecologic Niche
Everything an organism needs to live and reproduce
abiotic conditions
air temp. and the amout of water the can tolortate
habbitat
where organism lives
Niche
how it lives in the habbitat
what organisms compiete for
food, shelter, water and space
biodiversity
the amout of a different species found in an area
Biodiversity hotspot
an area of high levels of biodiversity
keystone spices
a spices that has a greater impact in the ecosystem
Population despertion
when organisms seperate to 3 types of groups
clumpped
when resources are spread in a certain a
helps find a mate and protects from predators
uniformed
limited rescores or territory
when individuals compete
random
individuals just roam randomly
immigration
an animal establishes a home in a habitat because it has resources it can utilize or because the habitat is ideal for them
Emigration
an animal leaves its home because the habitat is no longer ideal for them and they need to find a more suitable environment
exponential Growth
an ideal amount of resources
food,water,space
logistic growth
when a population is running low on resources
Density dependent limiting factors
they are competition, predation, parasitism and disease
Density independent limiting factors
it is weather, natrual disastrers, and human activity
Disturbance in inviorment
physical agent, chemical agent, biological agent
Natrual disturbances
they are drought, tsunami, tornadoes, earthquakes, volcanoes, lightning fires, and floods
human disturbances
some fires, human settlement, agriculture, urbanization, mining, air population, water population, and cutting forest
ecosystem stabilaty
Its when all ecosystems are in a state of flux
a stable ecosystem
it can bounce back from a normal disturbance
ecosystem reasilience
it can bounce back type of ecosystem
secondar pioneer species
grass+small perennials-like weeds,grass,shrubs,firt pines-intermelate species and mature mixed conifer forest-climax community
primary pioneer speices
they are bare rock, lichens, lichens,mass ,lichens,mass, fungis
