The following factors affect the growth of living things:

1. Nutrition:

Nutrition refers to the food we eat and how our body uses it. The availability of appropriate nutrients in diet plays an important role, in the growth of an organism.

2. Hormones:

Hormones are chemical messengers, produced by the endocrine glands, situated in different parts of the body.

Growth Hormones:

These are produced from the pituitary gland, which is located at the base of the midbrain. The pituitary gland secretes an important hormone called pituitary hormones, or growth-stimulating hormones (GSH) which determines how tall an individual can be.
