The Role of Decomposers in Ecosystems

The video explores the food chain, focusing on producers like plants and their importance. It then delves into decomposers, such as fungi, bacteria, and invertebrates, explaining their role in breaking down dead matter into soil. The video provides examples of decomposers found in nature and discusses how some people farm decomposers like worms at home. It concludes by reflecting on the critical role decomposers play in the ecosystem.

What is the primary role of producers in the food chain?

• To provide shelter for animals

• To consume other organisms

• To produce energy through photosynthesis

• To decompose organic matter

What happens to producers and consumers when they die?

• They decompose into soil

• They turn into water

• They disappear completely

• They become fossilized

Which of the following is NOT a decomposer?

• Birds

• Bacteria

• Fungi

• Invertebrates

Where is a good place to find decomposers?

• In a swimming pool

• In a compost pile

• In a desert

• On a mountain peak

What does the presence of mushrooms on a tree indicate?

• The tree is producing fruit

• The tree is growing rapidly

• The tree is healthy

• The tree is dead or dying

What is one way people can farm decomposers?

• By raising fish

• By growing vegetables

• By planting more trees

• By keeping pet worms

What do worms produce that is beneficial for plants?

• Leaves

• Seeds

• Flowers

• Castings

Why are decomposers crucial to the ecosystem?

• They produce oxygen

• They break down dead matter

• They provide food for predators

• They create new species

What might the world look like without decomposers?

• Completely barren

• Covered in plant life

• Piled with dead organic matter

• Filled with living dinosaurs

What is the main topic of this video?

• The life cycle of plants

• The role of decomposers in the food chain
