| | An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. | | | A healthy ecosystem has lots of species diversity and is less likely to be seriously damaged by human interaction, natural disasters and climate changes. | | | The third type of living organism in an ecosystem are the decomposers. |

| | Management of the honey bee in the New World is currently threatened by the movement of, and hybridization with, an aggressive African strain of honey bee that was accidentally released in Brazil in 1956. | | | Pollination by honey bees, originally imported from Europe, is extremely important as well, but these bees are presently in decline, enhancing the importance of pollinators from natural ecosystems. | | | Humanity obtains from natural ecosystems an array of ecosystem goods— organisms and their parts and products that grow in the wild and that are used directly for human benefit. |

| | ecosystem |
| | Ecosystems can be large, such as the global ecosystem (the ecosphere), or small, such as the pools that collect water in the branch of a tree, and they can contain smaller systems. | | | However, major changes to an ecosystem, such as climate change, overpopulation, or the removal of a species, may threaten the system& sustainability and result in its eventual destruction. | | | These relationships are usually complex and finely balanced, and in natural ecosystems should be self-sustaining. |
