Question

how do natural events like wildfires or floods affect the distribution of organisms? include once specific thing for each

imagine a species of fish that lives only in freshwater. what challenges would it face if its habitat were affected by rising sea levels or saltwater intrusion?

why are temperature, light, and moisture considered influential abiotic factors?

Explanation:

1. Wildfires can destroy habitats, forcing organisms to relocate. For example, many small - animals may flee the burned area. Floods can disperse organisms by carrying them away or creating new wet - habitats that some species may colonize.
2. A freshwater fish species would face osmotic stress as saltwater intrusion changes the water's salinity, making it difficult for the fish to maintain proper water and salt balance. Rising sea levels can also flood and contaminate freshwater habitats.
3. Temperature affects the metabolic rates of organisms. Light is crucial for photosynthesis in plants and also influences the behavior of many animals. Moisture is essential for maintaining cell turgor in plants and for the survival of many organisms as it is involved in various physiological processes.

Answer:

1. Wildfires destroy habitats, causing relocation; floods disperse organisms.
2. Osmotic stress due to salinity change and habitat contamination.
3. Temperature affects metabolism, light is for photosynthesis and behavior, moisture is for physiological processes.
