3. Animal waste in water

Question 10

Ammonia

Answer 10

Compound used to make ammino acids and proteins

Question 11

Phosphorous cycle

Answer 11

The cyclic movement of phosphorous in different chemical forms from the environment to organisms, back to the environment

Question 12

Amino acids

Answer 12

A group of molecules in which NH4 plays a large role

Question 13

Assimilation

Answer 13

The process in which plants absorb N

Question 14

Ammonification

Answer 14

Nitrogen from animal waste or decaying bodies returned to the soil by bacteria

Question 15

Denitrification

Answer 15

Ammonia is converted back to N2 by specific kinds of bacteria and archaea and goes back to the atmosphere

Question 16

Hydrogen fixation

Answer 16

Nitrogen bonding with hydrogen

Question 17

Carbon cycle

Answer 17

Continuous moving of carbon from the living to the nonliving and back. Oxygen is released during the process

Question 18

Photosynthesis

Answer 18

the process by which plants and some organisms use sunlight to synthesize foods from carbon dioxide and water.

Question 19

Combustion

Answer 19

The burning of a substance (fossil fuels, forest fires, etc.) which releases carbon. Carbon then mixes with oxygen to make CO2. Fossil fuels and forest fires release a lot of carbon
