Ecology and Environment Quiz: How Green Is Your Knowledge?
From food webs to climate change, test how well you understand ecosystems, biodiversity, and the forces shaping our planet.
About this quiz
Ecology is full of everyday mysteries: how food chains begin, why decomposers matter, what happens when forests disappear, and how climate change affects the systems around us. This quiz turns those big environmental ideas into a quick knowledge challenge.
After working through questions on biomes, biodiversity, greenhouse gases, the water cycle, ocean acidification, keystone species, and endangered species protection, you'll get a clearer sense of your ecology strengths and the topics worth revisiting.
