Ecology II 
1
Term Definition 
Habitat A place where organisms live 
Population A group of individuals of the same species in a particular 
location. 
Community All of the populations of species in a given area. 
Ecosystem The community, together with the physical and 
chemical environment of a particular area. 
Biosphere All the earth's ecosystems interacting with the physical 
environment. This includes all life as well as the earth itself and 
the atmosphere. 
Ecological 
Niche 
The role an organism plays in its community, including its habitat 
and its interactions with other organisms. 
Succession The series of changes in a community over time. 
Pioneer 
species 
These are the first species to occupy a new habitat, starting new 
communities 
Climax 
community 
This is the stable community that is reached, beyond which, no 
further succession occurs. 
Taiga Russian word meaning swampy moist forest, boreal forest 
2
Two types of succession 
A. Primary Succession 
1. starts with bare rock or there is little or no soil 
2. first stage is called pioneer. 
a) plants that can break down rock with acids — 
pioneer species 
3. often takes an extremely long time, as no soil and few 
available nutrients for plants 
3
4
5
B. Climax Community 
1. final, stable stage plants are called the climax species. 
2. when an area has these plants it is called a climax community. 
3. Examples: 
a) New England forest: beech, sugar maple, or white birch 
b) Southeastern forest: oak, hickory, or pine 
c) Northwestern forest: Western Hemlock, Western Redcedar 
6
D. Secondary Succession 
1. When climax habitat destroyed then 
secondary succession takes place. 
2. Causes of destruction: 
7 
Volcanic Activity Flood/Landslide 
Tsunami Wildfire
8
9
10 
E. From Lake to Forest 
1. sediments collect on 
bottom of lake filling it 
in 
2. goes through same 
stages as forest 
3. becomes marsh, then 
bog, then land

Color the map according to the clues listed below. You may need to look at a map of North America if you 
get stuck. Place a check mark in the box once you have completed that step. 
1. The dotted lines represent the border between the U.S. and Mexico and Canada. All other lines show biome borders. Color the U.S. 
borders (dotted line) red. 
2. Northern Canada and Alaska are tundra –color the tundra light blue 
3. Most of Canada is boreal forest. Color the boreal forest dark green. 
4. The west coast of the U.S. is mainly Temperate forest where California is. The east coast, all the way to the center of the countryis also 
Temperate forest. Color the Temperate forest light green. 
5. The Midwest (middle of the country) is temperate grassland. Color the grassland yellow. 
6. The eastern edge of Mexico and Central America, Hawaii, and the Caribbean Islands are all tropical rain forests. Color those purple. 
7. There is a northwest coniferous forest located in the far corner of the U.S (northwest). Color the northwest coniferous forest brown. 
8. The great lakes and the lakes in Canada are freshwater. Find each freshwater lake and color it pink. 
9. The bodies of water surrounding the continent are salt water. Color the coastal areas dark blue. 
10. The western region of the U.S. as well as Northern Mexico is desert. Color the desert orange. 
11. The western edge of Mexico is temperate forest. Color it the same color as you did the other temperate forests. 
12. Color code the squares at the bottom to match your biome colors.
