Ecosystem Components and Interactions

Karen Chisen explains the biotic and abiotic components of ecosystems, highlighting their interdependence. Biotic factors include living organisms like plants and animals, while abiotic factors are non-living elements like air and sunlight. The video discusses how these components interact, the role of photosynthesis, and the impact of changes in abiotic factors, such as the Amazon rainforest fires. The importance of maintaining a balance between these components for ecosystem health is emphasized.

What are the two main components that make up an ecosystem?

• Plants and animals

• Herbivores and carnivores

• Producers and consumers

• Biotic and abiotic factors

Which of the following is a producer in an ecosystem?

• A lion

• A plant

• A decomposer

• A human

What type of consumer eats both plants and animals?

• Carnivore

• Omnivore

• Herbivore

• Decomposer

How do decomposers contribute to an ecosystem?

• By producing their own food

• By consuming only plants

• By providing sunlight

• By breaking down dead organisms

What happens if one factor in an ecosystem is changed or removed?

• Only biotic factors are affected

• Only abiotic factors are affected

• It affects the entire ecosystem

• Nothing changes

Which abiotic factors are essential for photosynthesis?

• Oxygen and nitrogen

• Temperature and pathogens

• Carbon dioxide and sunlight

• Minerals and bacteria

What was one of the consequences of the Amazon rainforest burning?

• Loss of habitats

• Improved climate conditions

• Decreased carbon dioxide levels

• Increased oxygen levels

Why is the relationship between abiotic and biotic components important?

• It is not important

• It affects only the abiotic factors

• It ensures the survival of organisms

• It helps in the growth of only plants

Which factor controls the development of organisms in an ecosystem?

• Abiotic factors

• Consumers

• Biotic factors

• Producers

What is the role of abiotic factors in an ecosystem?

• They are non-living and support biotic life

• They provide energy to consumers

• They are the living parts of the ecosystem

• They decompose dead organisms
