Test 1
One is a group of organisms that are all the same species the other is a group of organisms of different species
Same Species = Population
Different Species = Community
The largest water reservoir on earth?
The ocean
Ecosystem, Species, Genetic
Ecological Succession
Two types of Eutrophication
Natural and Cultural
The amount of light that is absorbed or reflected off of a surface
What is Albedo
An organism interaction in which two organisms are fighting over a resource
What is Competition
All of the land that drains into a specific body of water
What is a watershed?
smaller range of tolerance that makes them more prone to extinction
What is Climax Community
A major solar event that occurs on June 21 and December 21 each year. (Hint: it is the longest or shortest day of the year)
What is the Solstices or A solstice
Organism that alls Nitrogen gas being converted into biologically useable Nitrogen
Nitrogren Fixation
When a body of water has excess nutrients leading to low dissolved oxygen level and agal growth
What is Eutrophication?
Species not native to an are introduced by human transport
When a habitat is broken into different pieces by development
Habitat fragmentation
If a producer contains 1250 Kcal of energy how much energy will a tertiary consumers get?
1.25
How humans introduce nitrogen and phosphorus into the environment
Fertilizer
Type of plate boundary that is formed when two plate slide back and forth against eachother
What is a transform boundary
a reservoir that takes in more than it releases
What is a sink
When discussing human threats to biodiveristy what does HIPPCO stand for?
Habitat Fragmentation
Invasive Species
Population Growth
Pollution
Climate Change
Over Exploitation
Larger islands have more biodiversity and Islands farther from mainland have less biodiversity
What is the Island Biogeography Theory
Primary: Mosses and Lichens due to no established soil
Secondary: Small flowers, weeds, and grasses due to preexisting healthy soil
when adding or removing an organism from an areas food wed causes a ripple effect through the trophic levels
What are Temperature and Precipitation
Causes stress on marine life due to lack of available dissovled oxygen
Ocean Warming
What are the 4 ecosystem services give an example of each
Supporting ( root filtration, pollination,etc)
Regulating ( ocean regulating temperature, trees regulating carbon)
Provisioning (food crops, lumber, hunting)
Cultural ( fishing and hunting, ecotourism to natural parks, using plants for medicine sold as profit)
Direct effects of clearcutting
Soil Erosion
Increased soil and stream temp
Flooding and Landslides
What are the two issues that arise due to Tree Plantations
Loss of biodiversity and all the trees being the same age
Describe natural selection
Organisms that are better adapted to their environment survive and reproduce more offspring.
