Abiotic factors are things in an ecosystem that aren't alive.
Here are a few examples of abiotic factors in a rain forest:
1. Sunlight
2. Water
3. Soil
4. Rocks
Hope this helps!
Exchange of gases in fish is very efficient because of: the large surface area of the gills. the large surface area of the blood capillaries in each gill filament. the short distance required for diffusion – the outer layer of the gill filaments and the capillary walls are just one cell thick.
Albedo is the "whiteness" of a surface. It is a reflection coefficient, and has a value of less than one. The albedo of a surface is the ratio of radiation reflected from the surface to the incident radiation. Hope this helps. Have a nice day. Feel free to ask more questions.
