according to image 5, the movement of phosphorus between biological organisms and soil...

readily available organic phosphorus in the soil is assimilated by plants

in the savanna the lions visit the watering hole in the morning.

resource partitioning

5 different species of warblers...

resource partitioning of the seeds reduced competition, and the five different species can live in the same tree.

the weathering of ______ releases phosphorus.

rocks

distribution of aquatic biomes is based on which main factor?

salinity

this biome is characterized by long dry seasons and is dominated by grasses, shrubs, and grazing animals.

savanna

based on image 5, which of the following reservoirs contain the most phosphorus?

sediments

in the nitrogen cycle illustrated above, nitrification occurs in which of the following steps?

step 3

in a fish species...
