Nutrients Cycles

Question 1

Water Cycle

Answer 1

CONDENSATION:
When gas(water vapor) turns into liquid when cool
gas ➡ liquid

EVAPORATION(TRANSPIRATION):
When water turns into gas when hot
liquid ➡ gas

PRECIPITATION:
When condensed gas lets out liquid that falls to the ground. When a cloud becomes to heavy it will let water fall.
*human impacts* 
*deforestation 
* withdrawals

Question 2

Phosphorus Cycle

Answer 2

When phosphate rock is is mined, weathered down or fertilized it will be taken up by plants. and then is eaten by animals.

• human impacts*
• can increase growth pf algae and duckweed which prevents sunlight and oxygen from entering the water
• by mining it may runoff into water which can cause water to be unliveable

Question 3

Carbon Cycle

Answer 3

The atmosphere contains carbon dioxide which is used by green plants in the process of photosynthesis. All organisms use the glucose for energy the organisms then break them down through cellular respiration, carbon dioxide is released back into the atmosphere. Fossil fuel combustion also releases carbon back into the air.

• human impacts*
• deforestation- reduces the amounts of plants to reduce carbon dioxide
• burning fossil fuels- returns carbon dioxide back to air
