Decomposition

Decomposition is the process of breaking down organic materials into simpler chemicals, essential for maintaining healthy ecosystems. It ensures the recycling of finite organic material to support new organisms and growth. Key requirements for decomposition include decomposing bacteria, fungi, warmth, moisture, and oxygen.

What does the decomposition process involve?

• Combining chemicals into complex structures

• Breaking down organic matter into simpler chemicals

• Creating new organisms from scratch

• Preserving organic material indefinitely

Why is decomposition essential for ecosystems?

• It recycles finite organic material

• It stops the growth of new organisms

• It creates new ecosystems

• It eliminates all bacteria

What happens to organic material in a living system?

• It is constantly recycled

• It is destroyed completely

• It remains unchanged

• It is never reused

What is a key requirement for decomposition to occur?

• Presence of decomposing bacteria and fungi

• Cold temperatures

• Lack of oxygen

• Absence of moisture

Which of the following is NOT necessary for decomposition?

• Oxygen

• Moisture

• Warmth

• Sunlight
