Frequently asked questions: Nature & Ecology
A preview of what awaits you in this nature & ecology quiz: 15 multiple choice questions, each with a detailed explanation so you can learn as you play. Here are a few sample questions (and their answers, so no cheating before you play!).
Which greenhouse gas is mainly responsible for current global warming?
Answer: Carbon dioxide (CO₂). Carbon dioxide (CO₂) is the main greenhouse gas responsible for current global warming, because of the huge quantities released by burning fossil fuels. Methane is more potent per molecule, but CO₂ is emitted in far greater quantities.
Which ocean phenomenon, linked to warming waters, bleaches and kills corals?
Answer: Coral bleaching. Coral bleaching occurs when the water becomes too warm, causing corals to expel the symbiotic algae that give them their colour. Without these algae, the corals turn white and die if they do not recover quickly.
What is the main role of bees in ecosystems?
Answer: Pollinating flowering plants. The main role of bees in ecosystems is pollination. As they forage from flower to flower, they carry pollen and make possible the reproduction of more than 80% of flowering plants, including many food crops.
Which type of forest has the greatest biodiversity on land in the world?
Answer: The tropical rainforest. The tropical rainforest has the greatest land biodiversity in the world. Although it covers only 6% of the Earth's land surface, it is home to more than 50% of known plant and animal species. The canopy alone is an ecosystem of extraordinary richness.
What is the role of wetlands (marshes, peatlands, mangroves) in the ecosystem?
Answer: They filter water, store carbon and protect against flooding. Wetlands play a major ecological role: they naturally filter water by trapping pollutants, store huge amounts of carbon (peatlands hold twice as much carbon as all the world's forests), and act as natural sponges against flooding.
