List 2 Biotic factors
Living examples
Give one example of an autotroph and one example of a heterotroph.
Autotroph: Plants
Heterotroph: Animals, insects, bacteria, fungi
Define Carrying Capacity
The maximum population an ecosystem can sustain
What is the term used to define the first organism to colonize an area?
Pioneer species
What is another term for the water cycle?
Hydrologic Cycle
Define "populaiton"
All of the same species that live in an area
Draw a food chain
Grass
Rabbit eats grass
Raccoon eats rabbit
Wolf eats raccoon
Grass --> Rabbit --> Raccoon --> Wolf
Density Dependent limiting factor:

Dependent: Food, water, shelter
Independent: Natural Disaster
What is the term used to describe the final ecosystem that forms during succession?
Climax Community
Which cycle does not have a form in the atmosphere
phosphorus cycle
List 4 factors that would belong to a community
Only living factors
Bush --> Deer --> Fox --> Coyote
What is the tertiary consumer
Coyote
Density Dependent
What type of succession occurs when a new island is forming from a volcanic explosion?
Primary Succession
What is the term used to describe how plants release water into the atmosphere?
Transpiration
List 6 factors that would belong to an ecosystem
must list biotic and abiotic factors
bush --> deer --> Fox --> coyote
If the deer passes 13,000 kCal of energy to the fox, how many kCal will the coyote gain from the fox?
1300
An irresponsible camper did not put out their campfire properly before leaving their campsite. The fire quickly spread through the forest because of the recent droughts. Many populations perished in the fire. What type of limiting factor is this?
Density Independent

Use picture #2 to answer this question
Review the food web. Choose 1 food chain from the web that has 4 trophic levels. Draw an energy pyramid. Place the organisms on the correct level. Label the feeding relationships on the RIGHT (producer...) label the Energy flow on the LEFT. The producers begin with 180,000 kCal of energy.
Draw together
