Ecosystem Roles and Energy Flow

The video explains how organisms in an ecosystem obtain energy, highlighting the roles of producers, consumers, and decomposers. Producers, mainly plants, use photosynthesis to create food. Consumers, including herbivores, carnivores, and omnivores, obtain energy by eating other organisms. Decomposers like bacteria and fungi break down dead matter, recycling nutrients back into the ecosystem. The video encourages viewers to explore local ecosystems to identify these roles.

What is the primary way that producers obtain energy?

• Through photosynthesis

• By absorbing nutrients from the soil

• By eating other organisms

• By decomposing dead matter

Which of the following is NOT a characteristic of producers?

• They consume other organisms

• They release oxygen

• They make their own food

• They use sunlight for energy

What is the main function of producers in an ecosystem?

• To consume other organisms

• To decompose dead organisms

• To provide energy for consumers

• To hunt other animals

What type of consumer only eats plants?

• Carnivore

• Omnivore

• Herbivore

• Decomposer

Which type of consumer eats both plants and animals?

• Producer

• Omnivore

• Carnivore

• Herbivore

Which of the following is a characteristic of a consumer?

• They make their own food

• They decompose dead matter

• They use sunlight to produce food

• They obtain energy by eating other organisms

What role do decomposers play in an ecosystem?

• They break down dead plants and animals

• They hunt other animals for food

• They produce food through photosynthesis

• They consume only plants

Which organisms are typically decomposers?

• Herbivores and carnivores

• Bacteria and fungi

• Plants and trees

• Omnivores and producers

What is released back into the ecosystem when decomposers break down dead matter?

• Sunlight

• Oxygen

• Nutrients

• Carbon dioxide

What should you look for when exploring an ecosystem to identify producers?

• Animals that eat other animals

• Plants that perform photosynthesis

• Organisms that decompose matter

• Animals that eat plants
