Final answer:
The three abiotic factors that influence the range of organisms living in rainforests are temperature, which affects organism metabolism and diversity; rainfall, which impacts soil quality and plant growth; and light availability, which is crucial for photosynthesis and understory plant growth.
Step-by-step explanation:
Three abiotic factors that influence the range of organisms living in rainforests are:
- Temperature: A crucial abiotic factor, temperature affects the metabolic rates of organisms and the types of plants and animals that can survive in rainforests. Consistently high temperatures in rainforests allow for a wide range of species to thrive.
- Rainfall: The amount of rainfall a rainforest receives influences soil quality and the types of vegetation that can grow. High rainfall leads to lush plant growth, which in turn supports a diverse array of animal species through food and habitat.
- Light availability: Sunlight penetration through the dense canopy influences how plants can survive in the lower layers of the rainforest. The amount of light available affects photosynthesis and the growth of understory plants, which are crucial for the ecosystem.
These abiotic factors create an interconnected system that supports the high biodiversity found in rainforest biomes, affecting everything from plant migration to the overall ecosystem health.
