Review Direction: Choose the correct answer from the box to complete each statement.  CHOICES: Birth Rate Density-Independent Factors Emigration Exponential Growth Population Growth  Activity 1: The Carrying Capacity Glass Direction: Observe the teacher as they demonstrate the activity. Pay close attention to what happens as more marbles are added to the glass. Be prepared to answer the guide questions based on your observations.  Guide Question: 1. If more and more people keep moving into a town or city, just like the marbles filling up the glass, what do you think might happen in real life? 2020 2025 Carrying Capacity Learning Objectives: a. Define carrying capacity. b. Identify whether a growth curve describes exponential, liner and/or logistic growth. Carrying Capacity The maximum population size of species that the environment can sustain. Determined by the number of available resources (food, habitat, water).  Growth Patterns Related to Carrying Capacity 1. Exponential Growth (J-Curve) 2. Logistic Growth (S-Curve)  Exponential Growth (J-Curve) Occurs when resources are unlimited → Population grows very fast. Logistic Growth (S-Curve) Occurs when resources are limited → Population stabilizes.  Limiting Factors Disease Competition Predation Emigration and for Parasites Resources 1. Disease and Parasites Spread faster in dense populations, exposing more organisms to infections and increasing death rates. 2. Competition for Resources Organisms with better survival skills thrive and reproduce, while those struggling for resources decline.  3. Predation When prey is abundant, predator numbers grow, but when prey decreases, predator populations also drop.  4. Emigration As populations near their resource limits, individuals or groups leave to find better survival conditions.  Activity 2: TRUE OR FALSE Direction: Write TRUE if the statement is true, and FALSE if the statement is false. 1. Carrying capacity is determined by the number of organisms in an ecosystem. 2. Exponential growth occurs when resources are unlimited, and the population grows very fast. 3. When a population exceeds it carrying capacity, the environment can support it indefinitely. 4. Logistic growth occurs when resources are limited, and the population size stabilizes over time. 5. Limiting factors such as competition, disease, and predation can affect population growth and carrying capacity. 1. Carrying capacity is determined by the number of organisms in an ecosystem.
