Biotic potential refers to the inherent capacity of an organism to reproduce and increase in numbers when environmental conditions are optimal and resources are unlimited.
The Lindeman 10% law states that only approximately 10% of energy is transferred from one trophic level to the next, with the remaining 90% lost as heat, respiration, and incomplete consumption.
Ecological succession in freshwater ecosystems follows a predictable pattern starting with pioneer algae, progressing to submerged aquatic vegetation, then emergent plants, and finally leading to terrestrial vegetation as the habitat transitions.
Lotka-Volterra cycles show predator population lags behind prey by approximately 90 degrees, peaking after prey abundance increases.
Nitrogen and phosphorus from agricultural runoff and sewage cause algal blooms and eutrophication in Indian water bodies.
The CBD's post-2020 global biodiversity framework targets 30% land protection by 2030, known as the '30 by 30' target.
Niche partitioning allows different predator species to exploit different resources or hunting strategies, reducing direct competition.
Monoculture plantations reduce species and genetic diversity, making ecosystems more vulnerable to disturbances and less stable.
Desert organisms show adaptations like nocturnal behavior to avoid heat, and physiological mechanisms to conserve water.
High biodiversity ecosystems typically show Shannon index values between 2.5-4.0, reflecting greater species diversity and evenness.
