This law states energy cannot be created or destroyed, only transformed.

These two variables define a biome
Temperature and precipitation

This chart shows this type of population growth
Logistic
100
This is the term for number of individuals per area
Population density
100
This is the term for humans receiving benefits from nature
Ecosystem services

This is measure of disorder that increases with energy transformations
Entropy

These types of organisms breakdown dead material and recycle nutrients
Decomposers

A golden jackal follows a tiger as it hunts and feeds on the leftovers of its kills - known as this kind of species relationship
Commensalism
200
When an individual leaves a population for another, it's called this
emigration
200
This is an example of a regulating ecosystem service
water purification
300
This is a type of feedback loop where change is dampened and the system stabilizes
Negative feedback loop
300
Some species have disproportionate effects on their ecosystems relative to their abundance - a beaver is an example of this
Keystone species

This is a density dependent factor that affects the carrying capacity of a system
Disease, competition, predation, population size

The levels of energy transfer through an ecosystem are called these
trophic levels

The fossilized remains of a 3-4 million year old hominin specimen found in Ethiopia in 1974, named this, illuminated evolutionary history of human bipedalism and brain size.

In this equation, pi is the relative abundance of a species in system. H` is known as this.
Shannon diversity index

These terms make up the acronym IPAT, which describes the human population-driven factors in environmental degradation (usually expressed in equation form as I = P x A x T
Impact = Population x Affluence x Technology

These are three agents of disturbance; how human populations impact the environment
•Clearing of natural vegetation for growing crops, pasture, transportation and housing
•Selective harvesting of desirable species and introduction of alien ones
•Mining for coal and other minerals
•Draining of wetlands for agriculture and human settlements
•Introduction of chemicals into the environment
•Introduction of greenhouse gases into the atmosphere and climate change.
