Natural Selection and Adaptation Concepts

The video introduces abiotic and biotic factors in ecosystems, explaining how organisms compete for these resources. It illustrates natural selection through giraffes' height variations and discusses plant competition for sunlight and water. The video emphasizes adaptation and survival in changing environments.

What are the two main types of factors discussed in the video?

• Physical and Chemical

• Natural and Artificial

• Living and Non-living

• Abiotic and Biotic

Which of the following is a biotic factor?

• Fish

• Soil

• Sunlight

• Water

Which of the following is an abiotic factor?

• Animals

• Plants

• Bugs

• Sunlight

What is the term used to describe the process where organisms with advantageous traits survive and reproduce?

• Mutation

• Natural Selection

• Evolution

• Adaptation

In the giraffe example, what trait helped some giraffes survive better?

• Longer necks

• Stronger legs

• Better eyesight

• Faster speed

What is a common competition factor for plants?

• Space

• Nutrients

• Temperature

• Sunlight

Which tree is better adapted to get sunlight in the example given?

• The red tree

• The blue tree

• Both trees equally

• Neither tree

What might give the blue tree an advantage in competing for water?

• Taller height

• Stronger roots

• Wider leaves

• Thicker bark

What is the main idea of natural selection?

• Random chance determines survival

• All organisms survive equally

• Organisms with beneficial traits reproduce more

• Only the strongest survive

What is the result of organisms adapting to their environment?

• They stop evolving

• They have more offspring with the same traits

• They reproduce less

• They become weaker
