Unit 10 Review- Ecosystem stability

What is the carrying capacity of the following graph?

• 1000
• 8000
• 800
• 600

Growth of biological organisms which goes on unhindered when resources are unlimited.

• population density
• carrying capacity
• exponential growth 
• survivorship curve

Which of the following would be the most likely effect, if there were a sudden increase in the cricket population?

• There would be a decrease in the small bird population.
• There would be a decrease in the grass/flowers population.
• There would be a decrease in the mice population.
• There would be an increase in the grass/flowers population.

A species that is not native to an area is called: 

• Native Species
• Natural Species
• Invasive Species
• Symbiotic Species

Whenever a species is the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession.

• Pioneer Succession

• Pioneer Species

• Pillager Species

• Ecological Species

In a habitat that has never before been colonized; (volcanic activity or retreating glacier), this type of succession is the __________________ succession .

• Secondary Succession

• Third Stewardship

• Primary Succession

• Secondary Selection

Changes which take place on a disturbed or damaged habitat. (Examples include areas which have been cleared of existing vegetation (such as after clear-cutting a forest) and destructive events such as fires.)

• Primary Selection

• Secondary Stewardship

• Primary Succession

• Secondary Succession

succession that occurs in an area where soil is already present

• ecological succession 
• primary succession 
• secondary succession
• pioneer speciles

a stable ecological community that has reached equilibrium

• ecological succession 
• climax community
• secondary succession
• pioneer speciles

starts with bare rock followed by lichen

• primary succession 
• secondary succession
• both types of succession
