Final answer:
Interaction between abiotic and biotic factors is essential for a stable ecosystem, providing diverse resources and enabling the exchange of matter and energy necessary for life processes such as photosynthesis and nutrient cycling.
Step-by-step explanation:
Abiotic and biotic factors must interact to produce a stable ecosystem because neither abiotic factors alone nor biotic factors alone can maintain stability. The interaction between these two sets of factors provides diverse resources and conditions for life to adapt and thrive. For example, sunlight (an abiotic factor) drives photosynthesis in plants (a biotic factor), which in turn produce oxygen for animals to breathe. A stable ecosystem requires this continuous and intricate exchange of matter and energy.
Another way that abiotic and biotic factors interact is through the nutrient cycle. Biotic factors such as decomposing organisms break down organic matter, returning nutrients to the soil (an abiotic factor), which then become available for plants to absorb and use for growth, thus supporting the food web.
