Ecology & Environment quizzes
Climate, biodiversity, energy, pollution
Ecology & Environment tackles the planet's big issues: the greenhouse effect and climate change, biodiversity and endangered species, ecosystems such as forests, oceans and wetlands, the water and carbon cycles, air, soil and sea pollution, waste and recycling. It also covers renewable energy like solar, wind and hydropower, and international agreements such as the Kyoto Protocol and the Paris Agreement.
These ecology quizzes help you separate common myths from scientific facts and understand everyday environmental choices. They are free, they run on five difficulty levels from very easy to expert, and every answer is explained so you walk away with something clear to remember.

Frequently asked questions about Ecology & Environment
What is the greenhouse effect?
The greenhouse effect is a natural phenomenon: gases in the atmosphere such as water vapor, carbon dioxide and methane trap part of the heat radiated by Earth. Without it, the average temperature would be about -18 °C instead of roughly 15 °C. Human activities increase these gases, which strengthens the effect and contributes to global warming.
What is biodiversity?
Biodiversity is the variety of life at three levels: the diversity of species, the genetic diversity within each species, and the diversity of ecosystems such as forests, coral reefs and grasslands. It provides essential services, including pollination, soil fertility and food resources.
What is the difference between renewable and non-renewable energy?
Renewable energy comes from sources that replenish quickly or are practically inexhaustible on a human timescale: sun, wind, water, biomass and the Earth's heat. Non-renewable energies such as oil, coal, natural gas and uranium rely on limited stocks that took millions of years to form.
