Exploring Abiotic and Biotic Interactions in Ecosystems

The video explains the roles of biotic and abiotic factors in ecosystems. Biotic factors include living organisms like plants, animals, and bacteria, while abiotic factors are non-living elements such as sunlight, water, and soil. The video provides examples of interactions between these factors, such as plants using sunlight and water for growth, turtles seeking soil for temperature regulation, and bacteria decomposing organic matter to enrich soil. These interactions highlight the interconnectedness of living and non-living components in maintaining ecosystem balance.

What are the living components of an ecosystem called?

• Atmospheric gases

• Non-living factors

• Biotic factors

• Abiotic factors

Which of the following is NOT a biotic factor?

• Bacteria

• Sunlight

• Animals

• Plants

What do plants use to make food?

• Sunlight, water, and CO2

• Soil, temperature, and water

• Atmospheric gases and soil

• Sunlight and soil

Why do some turtles bury themselves in the soil?

• To stay cool when it's hot

• To escape predators

• To lay eggs

• To find food

How do elephants interact with water?

• They use it to bathe

• They avoid it

• They use it to find food

• They drink it to stay hydrated

What happens to a fish's body temperature in warm tropical waters?

• It stays constant

• It matches the water temperature

• It decreases

• It fluctuates

Why do some foxes grow a white fur coat in the snow?

• To find food

• To attract mates

• To stay warm and camouflage

• To avoid predators

What role do bacteria play in the soil?

• Producers

• Consumers

• Predators

• Decomposers

How do decomposers get their energy?

• By absorbing sunlight

• By consuming living organisms

• By photosynthesis

• By recycling dead organisms

What is the result of bacteria decomposing dead organisms?

• The soil becomes dry

• The soil becomes infertile

• Nutrients re-enter the soil

• The soil temperature increases
