Final answer:
The forest stratification leading to different levels of sunlight and thus various species in a mature forest is an example of a microhabitat. Stratification creates varying conditions for photosynthesis, influencing the distribution of organisms in both terrestrial and aquatic ecosystems.
Step-by-step explanation:
The variation in light levels in a mature forest, leading to the presence of various species, is an example of a microhabitat. The stratified layers of the forest, including the forest floor, understory, and canopy create different conditions of light availability. This vertical layering influences not only the distribution of plant species but also the animals and other organisms that depend on these plants for food and shelter. Photosynthetic organisms have adaptations to capture the light available to them, as in the case of plants in the rainforest floor that capture the minimal light filtered through the canopy.
Tropical rainforests demonstrate high net primary productivity and feature distinct vertical layers that create diverse and complex habitats. This stratification results in various microhabitats due to differing levels of sunlight, dictating the distribution of both plants and animals within the ecosystem. Photosynthesis is a crucial process for organisms here, driving the structure of not only terrestrial ecosystems but aquatic ones as well, where similar stratification can occur due to light penetration in water
