Plants as primary producers
Plants capture solar energy and make it available to the rest of the ecosystem through food webs. They are the base of almost all terrestrial food chains.
Mycorrhizal partnerships
Over 90% of plant species form symbiotic associations with fungi. The fungus extends the plant’s root system, enhancing nutrient uptake (especially phosphorus). The plant provides the fungus with sugars. These networks connect multiple plants and even different species. See mycorrhiza and mycelial networks.
Plant signaling and defense
Plants are not passive. They produce chemical defenses against herbivores, emit volatile compounds that attract predators of their attackers, and communicate through mycorrhizal networks. See plant signaling.
Pollination ecology
The co-evolutionary relationships between plants and their pollinators shape flower form, color, scent, and timing. See pollination.
Niche construction
Plants modify their environments — stabilizing soil with roots, changing soil chemistry with leaf litter, altering microclimates with canopy shade. See niche construction.
Why this matters
Understanding plants in their ecological context explains why biodiversity matters, how forests function, and how agriculture can work with rather than against ecological processes.
