population growth (vocab)
What is Niche
An organism’s “job” within an ecosystem
EX: A cardinal eating sunflower seeds, in turn fertilizing and planting the seeds
Immigration
Individuals going INto a population
EX: Moving to Spain from Portugal
Energy
Energy flows through an ecosystem starting with the primary producers
precipation
when water returns back to earth surface rain,snow,hail,sleet.
How many Characteristics of Life
8
symbiosis
Any relationship in which two species live closely together
EX: A bee and a wasp
Emigration
Individuals Exiting a population
EX: Moving from Spain to Portugal
Matter
Matter includes things like vitamins, minerals, elements, and all the nutrients required by organisms for growth and development
when liquid water turns into a gas
What is growth in development
growth- when something grows bigger
Development- puberty
Habitat
The area an organism lives in
EX: A cardinal in a tree
Exponential Growth
Given enough nutrients, an ecosystem could theoretically grow forever
When an ecosystem grows unhindered, that is called exponential growth
As the size of the ecosystem increases, the rate of growth increases as well
EX: Binary fission in bacteria
Matter matters
Organisms consume matter to gather the “building blocks” for those processes to happen
Transpiration
when planet allows water to evaporate through their leaves
Reproduction
when something makes something of its self
carrying capacity
The amount of individuals in a population able to be supported by the ecosystem
EX: 10 lions in the Serengeti
limiting growth
As a population gets closer to its carrying capacity, its growth slows down, eventually stopping, or becoming negative
This is called logistic growth
Carbon matters
All life is based on (made up of a lot of) carbon
All life requires a frequent supply of carbon in one way or another
oxygen matter
Oxygen is required to make energy in most living organisms, including humans
maintain stable internal condition
Limiting Nutrient
A single nutrient that limits the growth of an ecosystem based on its availability
Logistic Growth
Following a period of exponential growth, a population will fluctuate above and below its carrying capacity
Rocks store carbon in them in various forms
When these rocks get broken through weathering or erosion, that carbon is released into the ground for plants to absorb
Human activity
Certain human activities directly release carbon into an ecosystem
change over time
how organisms adapt to their environment
