Decomposers do not perform photosynthesis; they break down dead organic matter and recycle nutrients.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Decomposition - Process and Factors
Leaching involves the removal of water-soluble inorganic nutrients, which move downward in the soil and sometimes become unavailable to plants.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Decomposition - Process and Factors
Photosynthesis is a process performed by autotrophs, whereas decomposition includes leaching, fragmentation, humification, and mineralization.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Decomposition - Process and Factors
Fungi decompose complex organic matter into simpler substances, playing a crucial role in nutrient recycling.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Decomposition - Process and Factors
Leaching is the process by which water-soluble inorganic nutrients dissolve and percolate into the soil.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Decomposition - Process and Factors
Decomposers break down organic matter and recycle essential nutrients back into the ecosystem, maintaining nutrient balance.
