Ecosystem Components and Interactions

The video explains ecosystems, which are composed of living (biotic) and non-living (abiotic) components. Ecosystems are classified into biomes based on abiotic factors like sunlight and temperature. Biotic factors interact through competition for resources. Abiotic factors determine the types of life that can exist in an ecosystem. The interaction between biotic and abiotic factors creates unique ecosystems. Biodiversity is crucial for ecosystem resilience. Humans must be mindful of their impact on ecosystems and work to preserve them.

What is an ecosystem composed of?

• Only living organisms

• Only non-living components

• Both living and non-living components

• Only plants and animals

How are ecosystems classified into biomes?

• Based on the size of the area

• Based on the types of animals present

• Based on the number of plants

• Based on non-living factors

What is a common way biotic factors interact?

• Through isolation

• Through competition

• Through cooperation

• Through migration

Which of the following is an abiotic factor?

• Fungi

• Sunlight

• Plants

• Animals

Why can't forest trees survive in tundra environments?

• Excessive water

• Too much competition

• Lack of sunlight

• Inadequate temperature conditions

How do abiotic factors affect ecosystems?

• They only affect plant life

• They have no impact on ecosystems

• They only affect animal life

• They determine the types of biotic factors that can exist

What is biodiversity?

• The variety of life in an ecosystem

• The number of plants in a forest

• The number of animals in a desert

• The variety of abiotic factors in an ecosystem

What is the significance of preserving both biotic and abiotic factors?

• To reduce plant growth

• To eliminate competition

• To maintain ecosystem balance

• To increase the number of animals

What happens when there is a great variety of abiotic factors?

• Only animals can survive

• Fewer types of biotic factors exist

• More types of biotic factors can exist

• Only plants can survive

Why is it important for humans to be mindful of their impact on ecosystems?

• To increase biodiversity

• To ensure ecosystems we rely on are not harmed

• To increase the number of plants

• To reduce the number of animals
