Population Growth
The human population doesn't grow this way
The sea cow has gone extinct from what group
Humans
A cycle that takes water and brings it into the sky and then brings it back down to land
The study of population growth
Demo graphics
An organism that finds its own food and eats it
Heterotroph
This type of human growth is L shaped & the other is J shaped
Logistic growth and exponential growth
At least 680 species has gone extinct from this group
People
The cycle where nitrogen goes through multiple living and non-living things while also changing forms
The nitrogen cycle
When heat makes the water molecules grow in size
Thermal expansion
This role in an ecosystem can eat dead animals without getting sick
Scavenger
Improved healthcare, better laws, women's education, and family planning are all ways to reduce this problem
Overpopulation
Driving cars, growing cattle, and burning fossil fuels is one of the few ways this group hurts the world
How humans hurt the environment
The cycle where carbon travels through the atmosphere, into living organisms, then back into the atmosphere
The carbon cycle
A non-living factor in an ecosystem
Abiotic factor
This rule states that about only 10% of energy is passed down
Rule of 10's
These are the limits or slows based on the population (ex: an outbreak)
Density-dependent factors
Undrinkable water, bad air, and climate change has happened as a result of this group
Humans
What cycles take earth's resources and recycle them
A relationship in which one side benefits while the other is neither benefitted nor harmed
This looks like a straight line where the producer is at the bottom and the biggest consumer is at the top
Food chain
These are the limits or slows regardless of population (ex: a tornado)
In about 5,000 years there would be no ice and we'd have an average temperature of about 80 degrees Fahrenheit if this substance emission isn't reduced
Carbon
This cycle only makes 1% of a liquid that humans can use
The water cycle
An animal in a food chain that makes its own food
Autotroph
This pyramid helps show the levels of energy transferred
