Biotic And Abiotic Factors In Ecosystems Explained

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 temperature. The video provides examples of ecosystems, identifying both biotic and abiotic components, and concludes with a call to share the video.

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

• Do not contain DNA

• Made of cells

• Require energy

• Ability to grow and develop

What is an example of a biotic factor in an ecosystem?

• Temperature

• Bacteria

• Water

• Sunlight

Which of the following is considered an abiotic factor?

• Fish

• Tree

• Bacteria

• Air

Abiotic factors include all of the following EXCEPT:

• Water

• Lichen

• Temperature

• Fire

In an ecosystem, what role do abiotic factors play?

• They reproduce and grow.

• They are the living components.

• They interact with biotic factors.

• They are made of cells.

Which of the following is an example of interaction between biotic and abiotic factors?

• Fish swimming in water

• Sunlight warming the air

• Rocks forming in the ground

• Clouds moving in the sky

What is the main focus of the conclusion in the video?

• Listing all biotic factors

• Summarizing the interaction between biotic and abiotic factors

• Explaining the process of photosynthesis

• Describing the water cycle

What is the significance of understanding biotic and abiotic factors in ecosystems?

• To identify the largest animal

• To understand the interaction within ecosystems

• To calculate the amount of sunlight

• To measure the temperature
