Gannet Population Trends and Analysis

Mr. Balum introduces a lesson on the disruption of food chains and webs, focusing on gannet populations. The lesson involves analyzing a data table of gannet breeding pairs from 1995 to 2013, plotting this data on a graph, and identifying trends. Students are encouraged to consider factors affecting population changes, such as food availability, competition, and disease. The lesson aims to enhance understanding of ecological interactions and data interpretation.

What is the main focus of the activity sheet discussed in the video?

• The migration patterns of gannets

• The breeding habits of gannets

• The diet of gannets

• Changes in the population of gannets

Where do the gannets mentioned in the task live?

• In urban areas

• In dense forests

• On sandy beaches

• On rocky cliffs

What is the significance of the data table in the task?

• It provides population data over 18 years

• It lists the predators of gannets

• It shows the diet of gannets

• It describes the habitat of gannets

What is the purpose of plotting the data onto a graph?

• To compare with other species

• To practice drawing skills

• To easily spot trends in the data

• To create a colorful chart

What should you be careful about when plotting the graph?

• Ignoring the scale

• Using colored pencils

• Drawing freehand for creativity

• Using a ruler to ensure accuracy

What trend is observed in the gannet population from 1995 to 2009?

• A decrease in population

• A stable population

• An increase in population

• No change in population

What is one possible reason for the increase in gannet population?

• Less space for nesting

• Increase in available food

• Decrease in available food

• More predators in the area

What change is observed in the gannet population after 2009?

• A leveling off

• A rapid decrease

• A rapid increase

• A complete extinction

What could be a reason for the leveling off of the gannet population?

• Increased competition for food

• Less competition for food

• More breeding pairs

• More space available

What additional data is needed to understand the population trend post-2013?

• More data on gannet diet

• More data on gannet predators

• More data on gannet migration

• More data on population changes
