Explanation:

An ecosystem includes all living (biotic) and non - living (abiotic) components in a particular area. The first option has only two types of living organisms (chameleons and poison dart frogs), missing non - living and other living components. The third option has only a group of insects (crickets, fruit flies, moths), also missing non - living and other living things. The second option includes soil (non - living, abiotic), bromeliads (living, plant, biotic), and poison dart frogs (living, animal, biotic), which covers both biotic and abiotic components of an ecosystem.
