Adaptations and Competition in Ecology

The video tutorial by Miss Clark covers the classification and biodiversity unit for Year 11 WJEC science. It explains how organisms have morphological and behavioral adaptations to compete for resources and survive. The tutorial discusses the differences between intraspecific and interspecific competition and how factors like predation, disease, and pollution affect population numbers. The session concludes with a preview of the next topic on biodiversity conservation.

What is the primary focus of the unit discussed in the introduction?

• Photosynthesis and energy transfer

• Classification and biodiversity

• Genetic mutations

• Human anatomy

Which of the following is an example of a morphological adaptation?

• A wolf's hunting strategy

• A bird's migration pattern

• A swan's long flexible neck

• A fish's schooling behavior

How do behavioral adaptations differ from morphological adaptations?

• They are permanent and unchangeable

• They are related to an organism's actions

• They involve changes in physical structure

• They only occur in plants

Why do organisms develop adaptations?

• To improve their survival and resource acquisition

• To increase their size

• To become more intelligent

• To change their color

What is intraspecific competition?

• Competition within the same species

• Competition between plants and animals

• Competition between predators and prey

• Competition between different species

Which of the following is an example of interspecific competition?

• Two lions fighting for territory

• A rabbit and a deer competing for grass

• A flock of birds migrating

• A school of fish swimming together

What does the term 'intra' signify in intraspecific competition?

• Within the same species

• Above the species

• Outside the species

• Between different species

Which factor is NOT mentioned as affecting population numbers?

• Climate change

• Pollution

• Disease

• Predation

How can pollution impact local wildlife?

• By causing habitat destruction

• By improving habitat conditions

• By increasing food supply

• By reducing competition

What is the impact of predation on prey populations?

• It has no effect

• It stabilizes prey numbers

• It decreases prey numbers

• It increases prey numbers
