... higher feeding level. Most energy taken into an organism as food is lost to the environment as heat (only about 10% is actually used)! As you move up the food chain/web (trophic levels), the number of organisms decreases (as does the biomass- or the total weight of living matter at each level). ...

As water drains from sandy soils, it often carries nutrients along with it. This condition is called leaching. When nutrients leach into the soil ...
