What is an Organism?
An organism is a living thing that can carry out essential life functions such as growth, reproduction, and responding to stimuli. Organisms can be classified into different categories based on their characteristics and evolutionary history.
Types of Organisms
- Plants: Examples include trees, flowers, and grass.
- Animals: Examples include mammals, birds, and reptiles.
- Microorganisms: Examples include bacteria, viruses, and fungi.
Case Study: Human Organism
Humans are complex organisms that have a highly developed nervous system, allowing them to think, communicate, and interact with their environment. The human organism consists of different systems such as the respiratory system, circulatory system, and digestive system that work together to maintain homeostasis.
Statistics on Organisms
According to a study conducted by the World Health Organization, there are an estimated 8.7 million species of organisms on Earth, with only a fraction of them identified and documented. This highlights the incredible biodiversity present in the natural world.
