What causes mutations?
Error in DNA Replication or some type of radiation.
R vs K-Selected Species?
-R-selected species produce many offspring with little parental care.
- K-selected species produce fewer offspring and invest more resources in their care.
What is the equation called to determine the doubling time of a population?
The Rule of 70.
Non Point VS. Point Source!?
Point-source pollution is easy to identify. it comes from a single place. Nonpoint-source pollution is harder to identify and harder to address. It is pollution that comes from many places, all at once.
What is eutrophication?
Excessive amounts of nutrients which lead to algae blooms and massive die-offs.

Name an anthropogenic source of carbon dioxide.

Explain the difference between Generalist and Specialist species.

What is tolerance?
an organism's ability to survive and thrive within a range of environmental conditions.
What is the Greenhouse Effect?
It is the natural process that heats up the earths surface.
What does the T in "IPAT" stand for?
Which group of organisms contain the largest amount of species?
Insects.
What is an indicator species?
A species that indicates whether an environment is good or bad.
Describe Carrying Capacity.
The maximum population size of a biological species that can be sustained by that specific environment.
What weather is associated with El Nino?
El Niño refers to a naturally occurring climate pattern characterized by warmer-than-average sea surface temperatures in the central and eastern Pacific Ocean.
What type of pollution is hard to regulate?
Non Point Pollution
It comes from multiple places
What does the term organic refer to?

What does the "I" stand for in "HIPPCO"?

What is a "pioneer species"?
The first organism to colonize a new or disturbed area. Ex: "Lichens"
