- oxígeno (O2)

2. Productos de la nutrición animal:

- residuos orgánicos  

- dióxido de carbono (CO2)

Explanation:

Los alimentos son sustancias químicas que los animales ingieren a fin de que el organismo transforme dichos compuestos en nutrientes los cuales son requieridos para la generación, el crecimiento y la reconstrucción de células y tejidos.

El oxígeno (O2) es un nutriente escencial para la vida el cual se absorbe mediante el proceso de respiración. Este proceso posibilita la absorción de otros nutrientes obtenidos a través de la alimentación.

Los residuos orgánicos representan productos de la nutrición animal los cuales se descomponen naturalmente para formar parte de la materia orgánica. En animales, los desechos órganicos son eliminados a través de los excrementos o en la orina.  

El dióxido de Carbono (CO2) es un producto de la respiración. En animales, la respiración celular consume oxígeno y compuestos orgánicos con el objetivo de producir energía en forma de ATP. Como concecuencia del proceso de respiración, los animales liberan CO2 al medio ambiente.

How do plants use nitrogen?
antoniya [11.8K]

Answer:

Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.
