* A tree (biotic) absorbs sunlight (abiotic) to perform photosynthesis. This is a classic example where an organism uses an energy source from the non-living world to fuel its life processes.
* A fish (biotic) requires oxygen dissolved in water (abiotic) to breathe. This highlights the dependence of living things on the chemical composition of their environment.
* A cactus (biotic) has deep roots that access groundwater (abiotic) in arid environments. This shows how organisms adapt to use abiotic resources for survival in challenging conditions.
* A bird (biotic) builds its nest using twigs and leaves (biotic) collected from trees and secured with mud (abiotic). This example combines biotic and abiotic resources to create a structure for survival.
