This document discusses abiotic and biotic factors in an ecosystem. Abiotic factors are non-living physical and chemical conditions such as light, water, air, climate, and soil. Biotic factors refer to the living organisms in an ecosystem, including animals, plants, fungi, protists, and bacteria. The document explains that ecosystems are complex systems where abiotic and biotic factors interact and depend on one another, so damage to one part can have disastrous effects on the other parts.

1. ECOSYSTEM
ABIOTIC FACTORS AND BIOTIC FACTORS

3. ABIOTIC COMPONETS
ABIOTIC FACTORS ARE THE NON-LIVING THINGS IN AN
ECOSYSTEM THAT PLAY AN IMPORTANT ROLE IN PROVIDING
ORGANISMS WITH A SUITABLE HABITANT.
ABIOTIC FACTORS ARE:
• LIGHT
• WATER
• AIR
• CLIMATE
• SOIL AND HUMUS
• PHYSIOGRAPHIC FACTORS

4. BIOTIC COMPONENTS
BIOTIC FACTORS ARE REFERRED TO LIVING ORGANISMS OF AN
ECOSYSTEM.
BIOTIC FACTORS EXAMPLES ARE:
• ANIMALS
• PLANTS
• FUNGI
• PROTISTA
• BACTERIA

5. IMPORTANCE OF BIOTIC
AND ABIOTIC FACTORS
ECOSYSTEMS ARE COMPLEX INTEGRATED SYSTEMS WHERE BIOTIC AND
ABIOTIC FACTORS INTERACT WITH EACH OTHER,
• FOR EXAMPLE A FOREST AND ANIMALS
• AN OCEAN WITH AQUATIC ANIMALS AND
• SOIL WITH TREES.
THE PARTS OF AN ECOSYSTEM DEPEND ON ONE ANOTHER AND WHEN
ONE PART OF THE ECOSYSTEM IS DAMAGED IT WILL HAVE A DISASTROUS
EFFECT ON THE OTHER PART.
