The Western Ghats contains about 60% endemic plant species, making it one of India's most critical biodiversity areas.
Decomposer bacteria have generation times measured in hours to days, making them have the shortest lifespan compared to other organisms in the ecosystem.
Agriculture accounts for ~70% of water use in India and will face severe stress due to changing precipitation patterns and increased evapotranspiration.
Ecological resilience is the capacity to recover from disturbances and return to equilibrium state.
Biological control using natural enemies provides sustainable, long-term management without ecological disruption.
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.
Energy pyramids always show decreasing energy upward and cannot be inverted, making them the most reliable representation.
Inverted pyramids occur when individual organisms at lower trophic levels are larger (e.g., one tree supporting many insects).
