APES phosphorus cycle

where does phosphorus NOT come from in order to enter the cycle?

• mountains

• atmosphere

• hills

• forests

where can the inorganic phosphate first be distributed into the cycle?

• soil and water

• mountains

• atmosphere

• Is not distributed in beginning of cycle

Where do the animals get the inorganic phosphate?

• oceans

• rocks

• themselves

• plants

what is mineralization

• when phosphorus is in inorganic form, ready to be absorbed by animals

• when phosphorus is in organic form, ready to be absorbed by plants

• when phosphorus is in inorganic form, ready to be absorbed by plants

• when phosphorus is in oranic form, ready to be absorbed by animals

when phosphorus gets washed into the ocean, the process is similar to when the phosphorus is distributed into the plants

• true

• false

people do not have an impact over the phosphorus cyccle

• true

• false

After the animals excrete the phosphorus, are decomposers able to use the phosphorus?

• yes

• no

what do humans use in order to be involved in the phosphorus cycle?

• fertilizer

• hair dryer

• detergents

• washing machines

what is the first step of the phosphorus cycle

• plants are decomposed

• The plants take up the inorganic phosphate from soil

• Through the weathering and erosion of rain, wind, and other causes, the inorganic phosphate ions and minerals are distributed into soil, and water

• Through the weathering and erosion of rain, wind, and other causes, the organic phosphate ions and minerals are distributed into soil, and water

what indicates that phosphorus does not come from the atmosphere in the diagram?

• the seperation of the steps

• the groupings of the steps

• arrows are connected

• the arrows are not connected
