Kudu Population Dynamics and Ecology

This video tutorial, led by Mr. P, covers worksheet question 3 on population ecology. It explains the graph representing population changes of kudu and wild dogs in a closed habitat over 35 years. The video discusses the predator-prey relationship, carrying capacity, and the consequences of exceeding this capacity. It also includes calculations of percentage increase and trends in population data. The tutorial aims to enhance students' understanding of graphs and prepare them for their final assessment.

What is the main focus of the video tutorial?

• Exploring the history of ecology

• Understanding population ecology through graphs

• Learning about different animal species

• Studying plant growth patterns

Why is it important to understand the scale and units of the graph?

• To make accurate calculations and interpretations

• To predict future population trends

• To identify the species shown in the graph

• To determine the habitat type

What does the dotted line labeled 'A' on the graph represent?

• The starting population size

• The average population size

• The environmental carrying capacity

• The maximum population size ever recorded

What type of relationship is depicted between kudu and wild dogs?

• Mutualistic relationship

• Competitive relationship

• Commensal relationship

• Predator-prey relationship

What could happen if the kudu population exceeds 700?

• The wild dog population will initially increase

• The kudu will migrate to a new area

• The wild dog population will remain stable

• The habitat will expand

How is the percentage increase in the wild dog population calculated?

• By subtracting the initial population from the final population, dividing by the initial population, and multiplying by 100

• By dividing the final population by the initial population

• By multiplying the initial population by the final population

• By adding the initial and final populations

What trend is observed in the kudu population from 1987 to 1994?

• The population remains constant

• The population increases

• The population decreases

• The population fluctuates

Between 1994 and 2008, what happens to the kudu population?

• It remains constant

• It decreases

• It becomes extinct

• It increases

What is the overall trend of the kudu population from 1987 to 2015?

• Decrease, then increase, then decrease

• Increase, then decrease, then increase

• Constant throughout

• Fluctuates randomly

What is the purpose of the video tutorial?

• To explore different ecosystems

• To discuss climate change

• To introduce new species of animals

• To prepare students for their final assessment
