Arrow C
It indicate cellular respiration in which organisms utilise atmospheric O2 gas for respiration ( O2 is the result of photosynthesis )and metabolize nutrients . All animals and plants / single or multicelled perform cellular respiration .
Add Answer to:

Which process fixes carbon (i.e., captures carbon and incorporates it into a living thing)? A. fire B. Respiration C. carnivory D. photosynthesis Plants manufacture a wide variety of carbohydrates, oils, and proteins, all of which contain carbon atoms. Where do plants get the carbon atoms? A. from water B. from soil C. from the atmosphere D. from sunlight “Fossil fuels” developed from A. Carbon-rich deposits of limestone that went through complex chemical changes. B.

What is released as a product of cellular respiration during the Krebs cycle? A Carbon dioxide (CO2). B. Pyruvate C. Glucose D. Acetyl CoA. QUESTION 36 Which of the following is TRUE regarding mutations? A. They always cause diseases. B. They always benefit an organism. C. They can be completely harmless, D. They stop evolution from occurring,

NPP = GPP – R
Net primary production =
______________
= GPP – energy used for cellular respiration
Gross primary production = ________________ production of
primary producers
Respiration = ______________________
Thus NPP is the amount of energy available to primary
consumers = primary production
Explain the different ways in which primary production is
influenced in terrestrial and aquatic ecosystems
Primary production: terrestrial
ecosystems influenced by water, temperature, and
nutrient availability
Evapotranspiration rate measures the amount of
water entering the atmosphere...

Background: Ancient lycophytes were the dominant plants on Earth during the Carboniferous Period, which is named for the coal that formed from those ancient plants that lived 300 million years ago. As humans use fossil fuels such as coal and gas, we release carbon in the form of carbon dioxide (CO2) into the air. Because CO2 traps heat near the surface of the earth, it is known as a greenhouse gas and contributes to climate change. However, carbon is also...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
