Mesocosms Simulate Ecosystem Processes in a Controlled Setting
- If you were tasked with creating a miniature ecosystem in a jar.
- How would you ensure it remains stable over time?
- This is the essence of mesocosms which are controlled environments that model natural ecosystems.
Definition
Mesocosms
Mesocosms are controlled experimental systems that replicate natural ecosystems, allowing scientists to study how variables like nutrient cycling and energy flow affect stability.
Key Elements Make Mesocosms Function
NoteThe video above is categorized on the old syllabus but its contents remain just as useful to you today.
- To create a sustainable mesocosm, all essential components of an ecosystem must be included:
- Autotrophs: Plants or algae to produce oxygen and organic matter.
- Consumers: Herbivores and carnivores to simulate food webs.
- Decomposers: Bacteria and fungi to recycle nutrients.
- Abiotic Factors: Soil, water, light, and temperature to maintain stability.
A balanced mesocosm must include all trophic levels to replicate ecosystem sustainability.
