Answer 28

rely on suns energy, water, co2 to create glucose and oxygen

Question 29

consumers (heterotrophs)

Answer 29

use oxygen and glucose and place co2 and water back into the atmosphere

Question 30

biochemical cycles

Answer 30

when elements, chemical compounds etc. are passed from one organism to another from one part of biosphere to another - water carbon, nitrogen, phosphorus cycles

Question 31

water cycle

Answer 31

Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Question 32

what is steos in the carbon cycle

Answer 32

Carbon enters the atmosphere via carbon dioxide. 2. Carbon dioxide is absorbed and used as energy. 3. Carbon compounds enter the food chain. 4. Carbon reenters the atmosphere via decomposition. 5. The carbon cycle repeats

Question 33

steps on nitrogen cycle

Answer 33

Nitrogen fixation Nitrification Assimilation Ammonification Denitrification

Question 34

nitrogen cycle: Nitrogen fixation

Answer 34

the process by which nitrogen is taken from its molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other biochemical processes.

Question 35

nitrogen cycle:Nitrification

Answer 35

the biological conversion of ammonia or ammonium to nitrite or nitrate.

Question 36

nitrogen cycle:Assimilation

Answer 36

process by which inorganic nitrogen compounds are used to form organic nitrogen compounds

Question 37

nitrogen cycle: Ammonification

Answer 37

When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen

Question 38

nitrogen cycle: Denitrification

Answer 38

the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere.

Question 39

phrospurs cycle

Answer 39

Weathering. Fertilizer. -Soil. -Direct Runoff. Excretion and Decomposition. Dissolved Phosphates (generally in ocean) Geologic Uplift.

Question 40

what is the human impact

Answer 40

carbon cycle- burning fossil fuels increase the amount of co2 in it which is too much to hold nitrogen/phrospurs cycle- fossil fuels+ fertilizer= severe altercations nitrogen- increase in harmful algal blooms
