key vocabulary

• founder effect: ____________ genetic diversity when a small group starts a new population

ecological succession
primary succession

• starts with ____________ environment
• first organisms: ____________ (combination of fungus and algae)

secondary succession

• begins with existing ____________
• occurs after ____________ or disruption of ecosystem

Explanation:

Population dynamics involves factors like births, deaths, and the resulting population change. Age - distribution impacts population growth in different ways depending on age - groups. Biotic potential is the maximum rate of population growth. Exponential growth means rapid population increase, while logistic growth levels off at carrying capacity. Carrying capacity is the maximum number of organisms an environment can support. The founder effect affects genetic diversity. Density - dependent factors are related to organism density. Primary succession starts with a barren environment and lichens (fungus - algae combination) are the first organisms. Secondary succession begins with an existing soil and occurs after a disturbance in the ecosystem.

Answer:

• Population Growth Factors: Births + Immigration - Deaths - Emigration - Population Change
• Population Characteristics:
• Pre - reproductive age: Future population potential
• Reproductive age: Current population growth
• Post - reproductive age: No population growth
• Types of Population Growth:
• Biotic Potential: Maximum rate for population growth
• Exponential Growth: Rapid population increase
• Logistic Growth: Population levels off at carrying capacity
• Key Vocabulary:
• Carrying Capacity (K): Maximum number of organisms an environment can support
• Founder Effect: Decrease in genetic diversity when a small group starts a new population
• Density - Dependent Factors: Population changes based on density of organisms
• Ecological Succession:
• Primary Succession:
• Starts with barren environment
• First organisms: Lichens (combination of fungus and algae)
• Secondary Succession:
• Begins with existing soil
• Occurs after a disturbance or disruption of ecosystem
