Understanding Biotic and Abiotic Factors in Ecosystems

The video from Moon Math and Science explains the difference between biotic and abiotic factors in ecosystems. Biotic factors are living elements like animals and plants, characterized by growth, cellular structure, response to stimuli, energy requirement, reproduction, and DNA. Abiotic factors are non-living elements such as water, air, and sunlight. The interaction between these factors defines an ecosystem. The video provides examples of ecosystems, identifying their biotic and abiotic components, and concludes with a call to share the educational content.

Which of the following is NOT a characteristic of biotic factors?

• Made of cells

• Require sunlight

• Contain DNA

• Ability to grow and develop

What is a key difference between biotic and abiotic factors?

• Biotic factors are non-living, abiotic factors are living

• Biotic factors require energy, abiotic factors do not

• Abiotic factors contain DNA, biotic factors do not

• Abiotic factors can reproduce, biotic factors cannot

Which of the following is an example of an abiotic factor?

• Tree

• Bacteria

• Fish

• Sunlight

In an ecosystem, which of these would be considered a biotic factor?

• Human

• Temperature

• Water

• Rock

Which of the following is NOT an abiotic factor?

• Ice

• Fire

• Air

• Lichen

What role do abiotic factors play in an ecosystem?

• They contain DNA

• They are the living components

• They interact with biotic factors to define the ecosystem

• They reproduce and grow

Which of the following is a biotic factor in a forest ecosystem?

• Rock

• Tree

• Temperature

• Sunlight

How do biotic and abiotic factors interact in an ecosystem?

• They do not interact

• Biotic factors depend on abiotic factors for survival

• Abiotic factors depend on biotic factors for energy

• They compete for resources
