Cellular respiration release co2 and photosynthesis absorbs co2. these two reactions are part of which biogeochemical cycle?
Naddika [18.5K]

The metabolic process that takes place in an organism's cells is called cellular respiration. Both photosynthesis and cellular respiration contribute carbon dioxide to the biogeochemical cycle.

<u>What is biogeochemical cycle?</u>

The mechanism that distributes and circulates abiotic chemical elements among the various realms of the planet is known as the biogeochemical cycle. The carbon, water, nitrogen, phosphorus cycle, etc. are all included.

Carbon dioxide is released during cellular respiration as a waste gas into the atmosphere, where it is then taken by plants to produce energy, which is then utilized by the organism, which then releases more carbon dioxide. The ecological chain's carbon cycle continues from the producer to the consumer.

Therefore, the carbon cycle is influenced by photosynthesis and cellular respiration.

In an exothermic reaction, heat is
GarryVolchara [31]

Answer:

B. the particles in the surroundings move faster and have increased entropy

Explanation:

An exothermic process releases heat, causing the temperatures of the surroundings to increase. Entropy increases as temperature increases. Since an exothermic reaction releases heat to the surroundings, molecules in the surroundings will begin to move faster because they will absorb more energy, which increases their kinetic energy. An increase in temperatures means that the particles of the surroundings have greater kinetic energy. The faster moving particals have more disorder than particles that are moving more slowly at a lower temperature. Entropy is interpreted as the degree of disorder/randomness.
