Ecosystem Interdependence and Food Chains

The video explains the role of decomposers like bacteria, fungi, and worms in breaking down dead plants and animals, converting them into nutrients that enrich the soil. This process is part of a continuous energy flow in ecosystems, known as the food chain, which involves producers, consumers, and decomposers. Examples of food chains in pond and land ecosystems are provided, illustrating how energy is transferred from one organism to another. The video also highlights the interdependence between plants and animals, emphasizing the exchange of nutrients and carbon dioxide.

What role do decomposers play in the ecosystem?

• They consume living plants.

• They break down dead organisms to enrich the soil.

• They provide shelter for animals.

• They produce food for plants.

What initiates the energy flow cycle in an ecosystem?

• Consumers eating producers.

• Animals breathing carbon dioxide.

• Decomposers breaking down waste.

• Producers using sunlight and nutrients to make food.

In a pond food chain, which organism is considered the producer?

• Eagles

• Algae

• Larger fish

• Small fish

Which of the following is a consumer in the pond food chain example?

• Algae

• Sunlight

• Small fish

• Soil

In the terrestrial food chain example, what does the caterpillar eat?

• Eagles

• Snakes

• Frogs

• Grasses and small plants

Which animal is at the top of the terrestrial food chain example?

• Caterpillar

• Snake

• Eagle

• Frog

What do microorganisms release into the air while decomposing animal waste?

• Hydrogen

• Nitrogen

• Oxygen

• Carbon dioxide

How do plants benefit from animals in the ecosystem?

• Animals protect plants from decomposers.

• Animals give carbon dioxide for plants to use.

• Animals provide oxygen for plants.

• Animals help plants to grow faster.

What happens to animals when they die in the ecosystem?

• They are consumed by other animals.

• They become producers.

• They disappear without a trace.

• They are reduced to nutrients and carbon for plants.

Why are plants and animals considered interdependent?

• They exchange nutrients and gases essential for survival.

• They both produce food for each other.

• They both rely on sunlight for energy.

• They both decompose to enrich the soil.
