Single-celled organisms, primarily bacteria and archaea, make up an estimated 70-90% of all living organisms on Earth in terms of abundance. In terms of biomass, they constitute a significant portion of the planet's total biological mass, with microorganisms playing crucial roles in ecosystems. However, the exact percentage can vary based on the specific environment and criteria for classification.
No, they do not. Because they have such a thin Cell Membrane, all the nutrients they need can be absorbed through diffusion or active transport.
Multicellular algae is crucial to the atmosphere, as it actually produces the greatest percentage of oxygen in our atmosphere, compared to other photosynthetic organisms.
Water constitutes a significant portion of most organisms, typically ranging from 60% to 90% of their total body mass. For instance, the human body is about 60% water, while plants can contain around 90% water. This high water content is essential for various biological processes, including nutrient transport, temperature regulation, and metabolic reactions. The exact percentage can vary widely depending on the species and environmental conditions.
Roughly 30% of fungi are known to be parasitic, meaning they obtain nutrients from living organisms. These parasitic fungi can cause various diseases in plants, animals, and humans.
Approximately 1% of the world's water is available for use by terrestrial organisms, with the majority of it being found in freshwater sources such as rivers, lakes, and underground aquifers. The rest of the Earth's water is saltwater or locked in ice caps and glaciers.
