Energy Flow in Ecosystems
Refers to the movement of energy through different organisms within an ecosystem.
Primary Productivity
The rate at which energy is converted by photosynthetic and chemosynthetic autotrophs into organic substances.
Trophic Levels
The hierarchical levels in an ecosystem consisting of producers, consumers, and decomposers based on their feeding relationships.
Biomass
The total mass of living or once-living organisms in a given area, often measured in grams per square meter.
Energy Transfer
The process of energy moving from one organism to another through consumption or decomposition.
Human Impact
The influence of human activities on disrupting energy flow in ecosystems, leading to consequences like habitat destruction and loss of biodiversity.
Pyramid of Energy
A graphical representation showing the flow of energy through different trophic levels, with energy decreasing as it moves up the pyramid.
Efficiency of Energy Transfer
The percentage of energy transferred from one trophic level to the next, with a significant amount lost as heat at each transfer.
