SUMMARY

Decomposers play a crucial role in the energy cycle by breaking down dead materials and releasing energy back into the ecosystem, although they are often not depicted in traditional food chains or webs. The primary distinction between the "pyramid of energy" and the "pyramid of biomass" lies in their measurement criteria; the pyramid of energy quantifies the energy released from burning a specific mass of an organism, while the pyramid of biomass measures the weight of completely dehydrated organisms. Understanding these concepts is essential for grasping ecological dynamics.

PREREQUISITES
  • Basic understanding of ecological concepts
  • Familiarity with food chains and food webs
  • Knowledge of energy transfer in ecosystems
  • Understanding of biomass measurement techniques
NEXT STEPS
  • Research the role of decomposers in nutrient cycling
  • Explore the concept of trophic levels in ecosystems
  • Learn about energy flow in ecosystems using the "10% Rule"
  • Investigate the implications of biomass versus energy in ecological studies
USEFUL FOR

Students studying ecology, educators teaching environmental science, and researchers interested in ecosystem dynamics and energy flow.

Homework Statement



1. can anyone tell me why decomposers are not shown in the food chain or food web?
2. what is the main difference between '' pyramid of energy'' and ''pyramid of biomass''?

Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
Decomposers may be represented in the food chain (reference)
 
uuummm... actually they should be shown coz they are part of the energy cycle, i.e they release the energy from dead materials back to the surrounding, hence completing the cycle...

pyramid of energy is more representative as compared to the pyramid of biomass. the pyramid of energy considers the amount of energy liberated whe a specific mass of that organism is burnt while the pyramid of biomass considers the weight of the completely dehhydrated organism.
