What determines the final size of a living organism?
In short: Explore the complex interplay between biology and surroundings. This video examines how genetic blueprints and environmental conditions dictate the growth and ultimate scale of plants and animals.
Growth is not determined by a single factor. For plants, development is shaped by both genetic instructions and local environmental conditions. For animals, the process is more multifaceted, involving genetic factors, the amount of food consumed, and various interactions with other organisms. While every species possesses a typical range for its adult size, these external variables play a critical role in how much an individual can grow.
