Examples of plant evolution
Secondary metabolites are essentially low molecular weight compounds, sometimes having complex structures, that are not essential for the normal processes of growth, development, or reproduction. They function in processes as diverse as immunity, anti-herbivory, pollinator attraction, communication between plants, maintaining symbiotic associations with soil flora, or enhancin… WebDec 26, 2024 · Classic examples include predator-prey, host-parasite, and other competitive relationships between species.
