Biodiversity above and below ground
Flowering plants are essential for biodiversity both above and below the ground. Below ground, they interact with microorganisms that provide nutrients to the plants or benefit from them. Fertile soil also contains spiders, worms, woodlice, moles, and mice, many of which rely on plants for food. When deceased animals decompose, they provide nutrients to the soil, benefiting the plants. Plants are thus a crucial link in the soil food web. When everything is thriving below ground, plants can flourish above ground as well. Many species, including butterflies, bees, bumblebees, beetles, and hoverflies, rely on flowering plants. They feed on pollen and/or nectar and play a role in pollinating the flowers during foraging. Larvae of various insects also feed on leaves and flowers, finding shelter among the plants. Insects, their larvae, and worms serve as food for small mammals, reptiles, and birds, which in turn become prey for larger mammals and birds. Finally, dead plants provide food for microorganisms. Thus, plants are also a vital link in the aboveground food web.
