Final answer:
The law of tolerance states that organisms have a range of tolerance for different abiotic factors. Limiting factors in terrestrial ecosystems include temperature and moisture, while in aquatic ecosystems, sunlight availability and the concentration of dissolved oxygen and nutrients are the main limiting factors.
Step-by-step explanation:
The law of tolerance states that organisms have a range of tolerance for different abiotic factors, such as temperature, moisture, sunlight, dissolved oxygen, and nutrients. Organisms can survive and function optimally within a certain range of these factors, but their growth and reproduction may be limited if they go beyond these limits.
In terrestrial ecosystems, limiting factors include temperature and moisture. Different plants and animals have specific tolerances for these factors, and they vary depending on the biome. For example, desert plants have adaptations to survive with limited water, while tundra animals are adapted to extreme cold temperatures.
In aquatic ecosystems, the main limiting factors are sunlight availability and the concentration of dissolved oxygen and nutrients. Sunlight is crucial for photosynthesis, which provides energy for aquatic organisms. Dissolved oxygen and nutrient levels vary from place to place in water bodies, influencing the types of organisms that can survive and thrive.
