Population Dynamics and Environmental Factors

The video tutorial by Meredith Miguel from Kubeneteon City Senior High School covers the concepts of biotic potential and environmental resistance affecting population growth. It explains how environmental resistance acts as a limiting factor, while biotic potential drives population increase. The tutorial also discusses carrying capacity, types of population distribution, and factors regulating population growth, including density-dependent and density-independent factors. The lesson aims to help students understand these ecological concepts and their impact on population dynamics.

What is the main focus of the lesson presented by Meredith Miguel?

• Classification of organisms

• Biotic potential and environmental resistance

• Photosynthesis process

• Human anatomy

Which of the following is a biotic factor affecting population growth?

• Parasitism

• Temperature

• Drought

• Fire

How does environmental resistance act in relation to population growth?

• It accelerates growth

• It acts like a hill pushing back

• It eliminates all organisms

• It has no effect

What does biotic potential measure in a species?

• The number of predators

• The adaptability and survival rate

• The amount of food available

• The temperature of the environment

What happens when a population reaches its carrying capacity?

• All organisms migrate

• Population growth accelerates

• Resources become unlimited

• Competition for resources sets limits

What is clump dispersion influenced by?

• Random chance

• Resource availability and behavior

• Territoriality

• Social interactions

Which type of dispersion is characterized by individuals being evenly distributed?

• Clump dispersion

• Random dispersion

• Clustered dispersion

• Uniform dispersion

What is the impact of high population density on disease transmission?

• Increases transmission rate

• Eliminates diseases

• Has no effect

• Decreases transmission rate

Which factor is considered density-independent in population regulation?

• Predation

• Competition for resources

• Natural disasters

• Territoriality

What is the relationship between population size and extinction risk?

• All populations have equal risk

• Population size has no effect

• Smaller populations have higher risk

• Larger populations have higher risk
