CED:165
what is water pollution?
CED:60
what is biodiversity?
what is cutting down of the forest called.
CED:121
what is deforestation?
this layer of the atmosphere protects Earth from harmful UV radiation.
CED: 190
what is the ozone layer
the maximum population size an environment can support is called?
CED: 76
what is carrying capacity.
when nutrients like nitrogen and phosphorus run into water and cause algal blooms.
CED:170
what is eutrophication?
The range of environmental conditions in which an organism can survive and reproduce is known as this.
CED:63
what is ecological tolerance.
this agricultural practice help prevent soil nutrient depletion by alternating the types of crops grown in a field each season.
CED:105
what is crop rotation?
when Earth gets warmer because gases trap heat in the atmosphere. this effect is called?
CED: 192
What is the greenhouse effect?
R- selected species have this type of offspring pattern.
CED: 73
what is many offspring with little parental care
disease transmitted by an infected mosquito bite.
CED: 183
what is zika and malaria
This type of species has disproportionately large effect on its ecosystem compared to its population size.
CED:65
what is a keystone species?
the removal of trees faster than forests can naturally regrow is?
CED:121
what is deforestation?
Hydrifluricarbons are commonly used in air conditioners and refrigerators and are classified as this type of atmospheric compound because they trap heat extremely efficiently.
CED: 191
What are greenhouse gases?
a population of deer grows from 450 to 630 individuals in one year. calculate the population growth rate percentage.
what is 40%
this occurs when organisms in higher trophic levels have more concentrated pollutants in them
CED:173
what is biomagnification
A behavioral or physical trait that improves an organisms ability to survive and reproduce in it environment is called?
CED:65
what is an adaptation?
When groundwater is pumped from an aquifer faster than it can be naturally replenished it results in this environmental problem.
CED:120
what is aquifer depletion?
a power plant emits 2.5 million metric tons of co2 annually. if emissions increase by 12% next year, how many metric tons of co2 will the plant emit
CED:200
what is 2.8 million metric tons of co2

CED:75
What is type 1 survivorship curve?
