ECOLOGICAL SUCCESSION for NEET – Conceptual Only

Ecosystem, NCERT LINE BY LINE, pre-class / Prof. Siddharth Sanghvi

Concept Description Community Response to Environment Communities change in composition and structure over time in response to changing environmental conditions. This change is orderly, sequential, and leads to a climax community, which is in near equilibrium with the environment. Ecological Succession The gradual and predictable change in species composition of a given area over time. […]

The pyramid of biomass in sea is generally inverted because the biomass of fishes far exceeds that of phytoplankton. Isn’t that a paradox? How would you explain this

Ecosystem, NCERT LINE BY LINE, pre-class / Prof. Siddharth Sanghvi

Concept/Reason Explanation Standing Crop The standing crop refers to the total biomass of organisms (like phytoplankton) present in an ecosystem at a given moment. In marine ecosystems, the standing crop of phytoplankton is small, but this doesn’t limit their ability to support consumers. Turnover Rate Turnover rate refers to how quickly organisms (like phytoplankton) are

Aspect Aquatic Ecosystem (Grazing Food Chain Dominant) Terrestrial Ecosystem (Detritus Food Chain Dominant) Primary Producers Mostly phytoplankton, which are consumed directly by herbivores. Dominated by plants, trees, and shrubs. Most plant biomass is not consumed by herbivores directly. Energy Flow Energy moves directly from primary producers (phytoplankton) to herbivores and higher trophic levels. A large
