Question 19

energy is conserved, neither created nor destroyed

Answer 19

1st law of thermodynamics

Question 20

entropy (disorder) increases in all natural systems; less energy is available to do work; it has not been destroyed, only dissipated.

Question 26

Essential for PHOTOSYNTHESIS Part of LIFE’s BIOMOLECULES Part of FOSSIL FUELS Major cause of GLOBAL WARMING

Answer 26

Carbon

Question 27

MOST ABUNDANT GAS in the atmosphere Converted into several form with the aid of different bacteria while in the cycle.

Answer 27

Nitrogen (N2)

Question 28

is the first step in the process of making nitrogen usable by plants

Answer 28

Fixation

Question 29

with the aid of lightning

Answer 29

Atmospheric fixation

Question 30

due to extremely high temperature

Answer 30

Industrial fixation

Question 31

with the aid of bacteria

Answer 31

Biological fixation

Question 32

This is the process by which ammonium changed into nitrates by bacteria. Nitrates are what the plants can then absorb.

Answer 32

Nitrification

Question 33

This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll.

Answer 33

Assimilation

Question 34

This is part of the decaying process. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium

Answer 34

Ammonification

Question 35

Extra nitrogen in the soil gets put back out into the air.

Answer 35

Denitrification

Question 36

Component of DNA, RNA, ATP, proteins and enzymes. Source: ROCK Released into the cycle through MINING and WEATHERING

Answer 36

Phosphorus

Question 37

enters the atmosphere as  hydrogen sulfide (H2S) during fossil fuel combustion volcanic eruptions decomposition.

Answer 37

Sulfur

Question 38

2nd abundant gas in the atmosphere WASTE product of PHOTOSYNTHESIS Essential for ENERGY PRODUCTION.

Answer 38

Oxygen Cycle

Question 39

also known as the hydrologic cycle, describes the continuous movement of water on, above and below the surface of the Earth.

Answer 39

Water Cycle
