Study Notes
Diversity in the Living World
- The living world encompasses an incredible range of organisms and habitats, including cold mountains, deciduous forests, oceans, freshwater lakes, deserts, and hot springs.
- The diversity evokes feelings of awe, illustrated by galloping horses, migrating birds, blooming valleys, and aggressive sharks.
- Two fundamental questions arise regarding life:
- What distinguishes the living from the non-living?
- What is the purpose of life? (Philosophical aspect not addressed by scientists).
1.1 Observing Diversity
- A diverse variety of living organisms can be observed in everyday life, from potted plants and insects to birds and pets.
- Many microorganisms exist that are not visible to the naked eye, contributing to the biodiversity around us.
- Expanding observation areas, like visiting dense forests, reveals an even greater number and variety of living organisms.
- Each distinct type of organism, whether plant, animal, or microbe, is classified as a species.
- The estimated number of known and described species is between 1.7 to 1.8 million, highlighting the vastness of biodiversity.
