There are many things which determine an organism's classification. In most cases features, physical traits and behavior patterns are used for classification.
DNA
genes and environment

The organisms genotype.
Chromosomes (DNA/genes).
No, genotype actually determines phenotype.
Biodiveristy determines prey and predators, giving organisms food sources and safety.
Animals that have that adaption to swim fast and eat other organisms that live in lake.
The water's temperature is the number one factor that determines the types of organisms that can live in a body of water. Organisms are adapted to specific temperature ranges, so water temperature directly influences the diversity and distribution of aquatic life.
One primary environmental condition that determines the success of an organism is temperature. Organisms have specific temperature ranges in which they can thrive, and deviations from this range can impact their metabolism, reproduction, and other life functions. Temperature affects enzyme activity, membrane fluidity, and overall physiological processes in organisms.
