The total of the variety of organisms in the biosphere.
What is Biodiversity?
100
The total area of the land and water ecosystems that provide the resources that each person uses.
What is Ecological footprint?
100
Smog, Acid Rain, Greenhouse Gases, and Particulates are all examples of this.
What is Air Pollution?

What is ecological footprint?
200
The nitrogen and sulfur compounds that are released into our air, as a result of burning fossil fuels, combine with water vapor to produce this type of precipitation.
What is acid rain?

A resource that can be reduced or replaced by healthy ecosystem functions.
What is a renewable resource?
300
The sum total of all different forms of genetic information carried by a particular species, or by all organisms on Earth.
What is the genetic diversity?
300
This term describes a place where significant numbers of species and habitats are in immediate danger of extinction.
What is an ecological hot spot?
300
