<span>Functional traits can be shared between organisms with divergent SSU rRNA sequences because functional traits may evolve independently, be shared through horizontal gene transfer, or be lost in divergent lineages.
Functional traits are characteristics that define our behavior.

<span>biomes vary in their rates of net primary production-biomass that remains after cellular respiration limited by sunlight and nutrients available
In general, warmer and wetter biomes have higher net primary productivity than colder and drier biomes. The reason for this trend is that plants require sunlight, water, and temperatures warm enough to grow. This is true even in aquatic ecosystems, where sunlight and the availability of nutrients determine the level of net primary productivity.</span>
