Feedback
An ecosystem includes biotic and abiotic components and their interactions.
Succession is the gradual change in species composition over time.
Solar energy is renewable; fossil fuels are non-renewable.
Biodiversity supports ecosystem services like pollination, water purification, and cultural value.
Noise pollution refers to excessive or disturbing sounds impacting health.
It safeguards wildlife and habitats to prevent illegal exploitation.
In-situ conservation protects organisms in the wild.
Habitat loss is a primary driver of species declines.
Ecosystem services include provisioning, regulating, supporting, and cultural benefits.
Water sustainability relies on protecting sources and prudent use.
Sustainability balances present needs with future generations' ability to meet theirs.
Environmental sustainability blends ecological, economic, and social aspects.
Energy transfer between levels is inefficient; most energy is lost as heat.
Deserts are defined by arid conditions and temperature extremes.
Coal, oil, and natural gas are finite resources. Solar, wind, and hydro are renewable.
Western Ghats and Sundaland are global biodiversity hotspots with high endemism.
Kyoto Protocol established binding emission targets for developed countries.
Chipko Movement involved tree-hugging to protect forests (also Silent Valley, Bishnoi).
Field work covers documentation of environmental assets: Rivers, Forests, Plants.
Solid waste management includes collection, segregation, recycling, composting, landfill.
