Ready? Begin!

What are some sources of phosphorous? Ocean sediment Question: Plant tissue Bones of terrestrial animals All of the above

In what state of matter is phosphorous usually found on Earth? Gas Question: Liquid Solid (as dust particles) Plasma

The most abundant form of phosphorous is… Diphosphate Question: Orthophosphate The element phosphorous Tetraphosphorous hexoxide

Where does the phosphorous cycle end? In mineral formations Question: In the ocean In the atmosphere A circle has no end

From which source can animals obtain their phosphorous? Plant tissue Question: Bones of other terrestrial animals Both of the above None of the above

How do terrestrial animals utilize phosphorous? Bone formation Question: Cellular plasma membrane Component of ATP All of the above

Phosphorous is most commonly harvested by humans for use in… Fertilizer Question: Pesticide Explosives All of the above

Why does phosphorous limit the growth of producer populations in many freshwater streams and lakes? Plants do not need Phosphorous Question: Phosphorous is very soluble in water Phosphorous is only slightly soluble in water Phosphorous does not affect growth of plants in freshwater ecosystems

How can an overabundance of phosphorous adversely affect aquatic ecosystems? Aquatic plants suffer from the toxic effects of phosphorous Question: Excessive plant growth and decay drains water of oxygen Explosive animal population consumes all of the primary producers It causes the water to taste bad, causing the animals to leave

Humans can add excess phosphate to aquatic environments through… runoff of animal wastes from livestock feedlots Question: runoff of phosphate fertilizers from farmland discharge of sewage All of the above
