Limiting Factors

What is an example of a density independent factor?

• Natural disasters such as hurricanes or wildfires.

• Population density of a species.

• Availability of food resources.

• Competition among species.

How do limiting factors affect population growth?

• Limiting factors have no effect on population growth.

• Limiting factors increase birth rates and decrease death rates.

• Limiting factors restrict the growth of a population by reducing birth rates or increasing death rates.

• Limiting factors only affect the population of plants, not animals.

What is the difference between density dependent and density independent factors?

• Density dependent factors are influenced by population size, while density independent factors affect populations regardless of size.

• Density independent factors are influenced by population size, while density dependent factors affect populations regardless of size.

• Density dependent factors are always negative, while density independent factors are always positive.

• Density dependent factors affect populations in urban areas, while density independent factors affect rural populations.

Can you name a density dependent factor that affects animal populations?

• Natural disasters

• Predation

• Climate change

• Habitat destruction

What is the term for the weakness in a population due to stress levels?

• Density Dependent Factors

• Environmental Resistance

• Carrying Capacity

• Biotic Potential

How does carrying capacity relate to limiting factors?

• Carrying capacity is independent of limiting factors.

• Carrying capacity is determined by limiting factors, which define the maximum population size an environment can sustain.

• Carrying capacity increases with the number of limiting factors.

• Carrying capacity is only affected by biotic factors.

What is the term for the number of organisms per unit area?

• Population

• Density

• Biomass

• Abundance

What are the factors in the environment that depend on the number of organisms in a population?

• Density Dependent Factors

• Climate Change Factors

• Geographical Factors

• Random Environmental Factors

What is the significance of understanding limiting factors in ecology?

• It helps in predicting weather patterns.

• Understanding limiting factors is crucial for conservation efforts and managing wildlife populations.

• It allows for the creation of artificial ecosystems.

• It is primarily used for agricultural productivity.

What are the factors that keep the number of organisms from growing too large called?

• Limiting Factors

• Exponential Growth

• Carrying Capacity

• Population Density
