Trivia Quiz On Ecology Nutrient Cycles And Succession!

A nutrient cycle is the unending movement of nutrients from the physical ecosystem into a living organism, and then it goes back into the physical environment. The health of the ecosystem depends on this. An ecological sequence is the procedure of change in the species structure of an ecological community over time. This quiz is all about ecology, nutrient cycles, and succession. You can do it.
