Leather tanning wastes contain high concentrations of chromium and other heavy metals that severely degrade aquatic ecosystems.
The Western Ghats contains about 60% endemic plant species, making it one of India's most critical biodiversity areas.
Ecological resilience is the capacity to recover from disturbances and return to equilibrium state.
Resource partitioning reduces competition by allowing species to utilize different niches (feeding at different heights).
Sundarbans face threats from climate change-induced sea level rise and human encroachment, reducing tiger habitat.
Antibiotic-resistant strains survive and proliferate while susceptible strains are eliminated, exemplifying natural selection.
Both cellular respiration by organisms and decomposition of dead organic matter release CO2 back into the atmosphere.
Earthquakes are density-independent factors. Density-dependent factors (competition, parasitism, disease) increase with population density.
Crabs in mangrove ecosystems regulate sediment composition and nutrient cycling, disproportionately affecting ecosystem structure.
Primary succession occurs on bare substrate with no pre-existing soil. Lichens and mosses are pioneer species.
