“describe how biogeochemical cycles provide organisms with the raw materials necessary to synthesize complex organic compounds”

The biochemical cycles can be defined as the nitrogen, carbon and phosphorous cycle. These cycle helps in renewing the nutrients back into the soil.

The nutrients like carbon, phosphorous and nitrogen are the basic nutrients for the formation of the complex organic compounds.

The nitrogen, carbon and phosphorous is brought into the soil and environment which helps in the synthesis of the complex organic substances.

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
