What process is represented by the blank in the diagram of the nitrogen cycle?

klemol [59]

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. ... Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.

Which is a biotic element found in the tropical rain forest biome

RideAnS [48]

Abiotic factors (non-living things) in a tropical rainforest include temperature, humidity, soil composition, air, and many others. A few of the many biotic factors (living things) in that forest are toucans, frogs, snakes, and anteaters. All of the biotic factors are dependent upon the abiotic factors

Which observation would provide indirect evidence that supports a hypothesis that the bubbles are o2 ?

zhuklara [117]

Explanation:

D. An increase in bubbles on the plant when it is moved under a brighter light.

The rate of photosynthesis increases with light intensity.

The process of photosynthesis is energy-storing, it converts light energy into chemical energy, which is stored in the bonds of glucose. Thus an increase in light intensity would increase the rate of photosynthesis, and more O2 bubbles would be produced as waste.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.

Occurring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage molecule ATP through an electron transport chain.

This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.
