Ecosystem Components and Functions

The video tutorial discusses the structure of ecosystems, focusing on the interaction between biotic and abiotic components. It explains the roles of producers, consumers, and decomposers in nutrient cycling and energy flow. The importance of abiotic factors like air, water, and sunlight is highlighted, along with the functions of ecosystems in maintaining ecological balance and stability.

What is the primary focus of the ecosystem structure?

• The interaction between organisms and their environment

• The classification of species

• The history of ecosystems

• The future predictions of climate change

Which of the following is NOT a biotic component?

• Soil

• Plants

• Animals

• Decomposers

What role do producers play in an ecosystem?

• They consume other organisms

• They regulate climate

• They decompose organic matter

• They produce food through photosynthesis

What is the main function of decomposers in an ecosystem?

• To regulate temperature

• To produce energy

• To consume plants

• To break down dead matter

What is the role of consumers in an ecosystem?

• To decompose organic matter

• To regulate climate

• To produce food

• To depend on other organisms for food

Which component is essential for photosynthesis?

• Minerals

• Sunlight

• Wind

• Humidity

Which of the following is a non-living component of an ecosystem?

• Animals

• Plants

• Water

• Decomposers

Which of the following is a function of the abiotic components?

• Producing food

• Supporting photosynthesis

• Consuming other organisms

• Decomposing organic matter

How do ecosystems maintain balance?

• By eliminating predators

• Through nutrient cycling and energy flow

• By increasing the number of species

• Through human intervention

What is the significance of nutrient cycling in ecosystems?

• It supports ecological balance

• It increases the number of species

• It prevents energy flow

• It reduces biodiversity
