Decomposer

The video tutorial explains the role of decomposers in ecosystems. Decomposers, such as earthworms, bacteria, and fungi, recycle dead plants and animals into nutrients, supporting plant growth. The video also covers the food chain, highlighting how energy flows from the sun to producers, consumers, and finally decomposers. Decomposers are crucial for nutrient cycling and ecosystem health.

What is the primary function of decomposers in an ecosystem?

• To provide shelter for other organisms

• To consume living plants and animals

• To recycle dead plants and animals into nutrients

• To produce energy from sunlight

Which of the following is an example of a decomposer?

• Shark

• Lion

• Eagle

• Earthworm

How do fungi contribute to the food chain?

• By breaking down dead matter into nutrients

• By producing food through photosynthesis

• By consuming herbivores

• By providing energy directly from the sun

What is the starting point of a food chain?

• Consumers

• The sun

• Carnivores

• Decomposers

Why are decomposers crucial for the survival of plants and animals?

• They recycle nutrients back into the soil

• They prevent the growth of new plants

• They provide direct energy to all organisms

• They consume all producers
