In the Amazon rainforest, abiotic variables include water, soil, climate, sunlight, and air. All populations and species in the Amazonia are dependent on the warm environment and water, whilst all plants are directly nourished by sunlight, oxygen, and soil nutrients.
Abiotic variables are nonliving components that influence the biotic or living species in a particular biome. The existence and quantity of abiotic elements are crucial to the life cycle of plants, animals, and the decomposition of once-living things in the Amazon. They also influence the adaption of rainforest plants and animals.
Liana, a climbing vine prevalent in the Amazon and other tropical jungles, is one example. Due to the low amount of sunlight on the forest floor, it attaches to trees and climbs to the forest canopy by climbing upward. When a liana reaches the treetop, it spreads to neighbouring trees and intertwines with other lianas to form a network of vines that protects shallow-rooted trees from high winds.
Due to the lack of soil nutrients in the rainforest, the trees that flourish there have shallow roots. Enormous and tall trees adapt by creating buttress roots or massive ridges that support the tree by fusing with the trunk. Due to the lack of sunshine on the forest floor, certain aerial plants rely on the warm, humid air for sustenance. To avoid relying on the low-nutrient soil, the majority of shrubs and bushes on the forest floor obtain nutrients from decomposing plant matter.
