Question

MATTER is recycled in an ecosystem, and ENERGY flows in and out and cannot be recycled.
true or false

Answer 1

True. In an ecosystem, matter is recycled through biogeochemical cycles, meaning that nutrients and elements are reused and transformed as they move through different organisms and the environment. In contrast, energy flows in one direction: it enters the ecosystem (typically from the sun), is converted into different forms by organisms, and is ultimately lost as heat, making it impossible for energy to be recycled within the ecosystem.
