EQ 2-7 species population dynamics

What is carrying capacity?

• A condition that occurs when two or more organisms compete for the same resources within an ecological community

• A relationship in which two organisms are mutually dependent on each other for survivial

• All the biotic and abiotic factors and the interactions among them in a given area

• The maximum number of organisms an ecosystem can support

What can occur when ecological niches overlap and multiple organisms seek the same resources?

• Symbiosis

• Resource partitioning

• Competition

• Predation

What are factors that affect carrying capacity?

• Biotic only

• Biotic and abiotic

• Depends on the ecosystem

• Abiotic only

Which statement best describes the predator-prey relationship displayed on this graph?

• There is no relationship between the predator and prey.

• When the prey population increases, the predator population decreases.

• When the prey population increases, the predator population increases.

• when the predator population increases, the prey population increases.

Which of the following is a biotic factor that would affect the carrying capacity of a population?

• Soil

• Predator

• Rainfall

• Sunlight

Which statement best describes the term limiting factors?

• All the biotic and abiotic factors and the interactions among them in a given area

• A finite resource organisms in an ecosystem require

• The biotic and abiotic factors in an ecosystem

• The maximum number of organisms an ecosystem can support

What is the carrying capacity of the following graph?

• 1000
• 8000
• 800
• 600

Will competition increase/decrease the carrying capacity of an ecosystem for the animal in competition?

• Decrease
• Increase

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow
• The population starts to die off to return to carrying capcity
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity
