Description of biogeochemical cycles

par Rebeca Aimé Lujan Flores
1

Biogeochemical cycles refer to how essential chemicals move from living things to non-living things and then back again.

Select one or more answers

2

Which chemical is good to make complex organic materials?

Select one or more answers

3

Which chemical is essential for the formation of proteins?

Select one or more answers

4

Which chemical is essential for celular respiration and we can also find it in water?

Select one or more answers

5

For one thing, the atoms in your body are not brand new. Instead, they've been cycling through the biosphere for a long, long time, and they've been part of many organisms and nonliving compounds along the way. You may or may not believe in reincarnation as a spiritual concept, but there's no question that atoms in your body have been part of a huge number of living and nonliving things over the course of time!

Explanation

Biogeochemical cycle, this name reflects the importance of chemistry and geology as well as biology in helping us understand these cycles.

About 18% of your body consists of carbon atoms, by mass, and those carbon atoms are pretty key to your existence!. Without carbon, you wouldn't have the plasma membranes of your cells, the sugar molecules you use for fuel, or even the DNA that carries instructions to build and run your body.

Nitrogen is a key component of the bodies of living organisms. Nitrogen atoms are found in all proteins and DNA

Why does it matter that there is lots of CO2 in the atmosphere? ​It is a greenhouse gas. When in the atmosphere, it traps heat and keeps it from radiating into space. Based on extensive evidence, scientists think that elevated levels of CO2 and other greenhouse gases are causing pronounced changes in Earth's climate. Without decisive changes to reduce emissions, Earth's temperature is projected to increase by 1 to 5°C by the year 2100.

Nitrogen exists in the atmosphere as N2 gas. In nitrogen fixation, bacteria N2 into ammonia, a form of nitrogen usable by plants. When animals eat the plants, they acquire usable nitrogen compounds.

Phosphorus is an essential nutrient for living organisms. It’s a key part of nucleic acids,like DNA and of the phospholipids that form our cell membranes. As calcium phosphate, it also makes up the supportive components of our bones.
