The children need discipline because of their behavior.
Los niños necesitan la disciplina debido a sus malos comportamientos.
For style reasons I'd like to rather propose "debido a su mal comportamiento", to make it a wider concept.

The children need to be disciplined because of their bad behavior.

The dog is growling because the cat is looking at him.

Umbrellas are needed because of the rain.
(Se) Necesitan (los) paraguas debido a la lluvia.
..."porque llueve".
* "los" is not necessary, but not incorrect.

"Porque" works in most of the cases, but the use of alternatives is correct in your sentences.

I'm doubtfulness in this text.

They left home because of their parents.
Ellos salieron de casa a causa de sus padres.

I guess that in the part of their could to take the phrase cause as in the translation at Spanish causa.

Then I guess that it could to be They left home to cause of their parents.

I don't know if am in the correct about it in, but just came in mind the idea about that change in the sentence.
