How do organisms harness energy for survival?
Quick fact
Metabolism is the collection of chemical reactions that keep organisms alive.
Why this is interesting
Every living thing needs energy, but life has evolved incredible ways to capture and use it.

Understanding How do organisms harness energy for survival?
Cells break down nutrients such as sugars and fats to release energy. This energy powers movement, growth, repair, and reproduction.
A deeper explanation
Metabolism connects biology and chemistry by showing how living systems use molecular reactions to maintain order and resist the natural tendency toward disorder.
