Ecosystem Roles and Interactions

The video explains ecosystems, highlighting the interaction between biotic and abiotic components. It details abiotic factors like climate and soil, and biotic components such as producers, consumers, and decomposers. The roles of different consumer types are discussed, concluding with a question about human consumer classification.

What is an ecosystem primarily composed of?

• Only living organisms

• Only non-living components

• Only water and soil

• Living organisms and their non-living environment

Which of the following is NOT a climatic factor in an ecosystem?

• Rain

• Temperature

• Soil pH

• Humidity

What role does the atmosphere play in an ecosystem?

• Provides nutrients for plants

• Stores water for plants

• Supplies carbon dioxide for photosynthesis

• Acts as a habitat for animals

Which component of an ecosystem is responsible for photosynthesis?

• Abiotic components

• Decomposers

• Producers

• Consumers

What is the primary role of producers in an ecosystem?

• To decompose organic matter

• To consume other organisms

• To produce their own food

• To provide shelter for animals

Which of the following is a characteristic of autotrophs?

• They produce their own food using sunlight

• They depend on other organisms for food

• They are the largest carnivores

• They decompose organic matter

Which type of consumer feeds directly on producers?

• Quaternary consumers

• Secondary consumers

• Primary consumers

• Tertiary consumers

What is the role of decomposers in an ecosystem?

• To produce food for plants

• To break down dead organic material

• To consume primary consumers

• To provide energy for photosynthesis

Which of the following is an example of a secondary consumer?

• Fox

• Deer

• Lion

• Rabbit

What distinguishes quaternary consumers from other types of consumers?

• They only eat plants

• They are the smallest carnivores

• They are not eaten by any other animals

• They feed on producers
