Both photosynthesis and cellular respiration are part of the carbon cycle. Which statement best compares these two processes? Both release carbon dioxide as waste. Both provide organisms with usable energy. Both add bacteria to the soil. Both require fixation in order to convert molecules.

Answers

Answer:

Both provide organisms with usable energy.

Explanation:

Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.

During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.

Both processes furnishes an organism with energy in the end. Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy. This energy is used by both plants and animals for their living activities.

Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical​

Answers

Answer:

Equation

Explanation:

the last word is Equation

Considering the definition of chemical reaction and chemical equation, A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical​ equation.

Chemical reaction

A chemical reaction consists of the formation of new substances (products) from others (reagents). In this process bonds of the reactants are broken and new ones are formed in the products.

In other words, a chemical reaction occurs when the substances participating in it are transformed into different ones. The mass of the participating substances is the same before and after the reaction, that is, it is conserved because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.

Chemical equation

Chemical reactions are represented by chemical equations. In them, the reactants are determined, the products are predicted, and the proportions of the substances that participate in the reaction are indicated.

Summary

A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical​ equation.
