Scavengers and Decomposers in Ecosystems

The video explains the roles of scavengers and decomposers in ecosystems. Scavengers, such as hyenas and vultures, consume dead animals, while decomposers like fungi and bacteria break down organic matter. Both are crucial for recycling nutrients. Scavengers initiate decomposition, and decomposers complete it. Despite their reputation, scavengers are vital for maintaining ecological balance.

What is the primary role of both scavengers and decomposers in an ecosystem?

• To create new species

• To recycle dead and decaying matter

• To provide shelter for animals

• To produce energy

Which of the following is NOT an example of a scavenger?

• Vulture

• Hyena

• Fungi

• Raccoon

What type of organisms are decomposers typically?

• Large mammals

• Birds

• Fungi and bacteria

• Reptiles

Which of the following foods is made using decomposers?

• All of the above

• Bread

• Yogurt

• Cheese

What is the main difference between scavengers and decomposers?

• Scavengers live in water, while decomposers live on land

• Scavengers produce food, while decomposers consume it

• Scavengers are larger animals, while decomposers are smaller organisms

• Scavengers are plants, while decomposers are animals

How do scavengers contribute to the decomposition process?

• By consuming living plants

• By creating new habitats

• By breaking down large pieces of dead matter

• By producing oxygen

Why might scavengers be considered unpleasant by some people?

• They are very noisy

• They destroy crops

• They are often smelly and associated with decay

• They are dangerous predators

What is the ultimate role of decomposers in the ecosystem?

• To start the decomposition process

• To complete the decomposition process

• To prevent decomposition

• To create new ecosystems
