vertical stratification of plants
Explanation:
vertical stratification is best explained as the vertical layering arrangements of vegetation in the rain forest habitat.
The vertical arrangement of trees is so significant to so many species in the forest because they are dependent on different vegetative layers. Each layer offers a distinct purpose to the habitat.
Producers, which are the base of the food chain for ecosystems are essential and do not require oxygen to cycle energy and matter, as they create oxygen through photosynthesis. Plants are producers that use this process to capture light energy and use it to convert carbon dioxide and water into an organic substance known as glucose.
