| 4217451239 | Autotroph | An organism that produces complex organic compounds from simple substances present in its surroundings, generally using energy from light or inorganic chemical reactions. |  | 31 |
| 4217451240 | Heterotroph | An organism deriving its nutritional requirements from complex organic substances. |  | 32 |
| 4217451241 | Dominant Species | The species that predominates in an ecological community, particularly when they are most numerous or form the bulk of the biomass. |  | 33 |

This ecosystem experiences high average temperatures and a significant amount of rainfall. |  | 40 |
| 4217451249 | Savanna | A type of woodland characterised by a very open spacing between its trees and by intervening areas of grassland. This lack of vegetation is due to the dry conditions present in such biomes, which means the distribution of water among organisms only allows the survival of a few. |  | 41 |

| 4217451254 | Tundra | A type of biome where the tree growth is hindered by low temperatures and short growing seasons. |  | 46 |
| 4217451255 | Wetlands and Estuaries | Bodies of water usually found where rivers meet the sea. Estuaries are home to unique plant and animal communities that have adapted to brackish water—a mixture of fresh water draining from the land and salty seawater. |  | 47 |
| 4217451256 | Lakes | An inland body of water, usually fresh water, formed by glaciers, river drainage, etc., larger than a pool or pond. |  | 48 |
| 4217451257 | Streams and Rivers | A large stream of water flowing in a bed or channel and emptying into the ocean, a sea, a lake, or another stream; a stream larger than a rivulet or brook. Transparent and sparkling rivers, from which it is delightful to drink as they flow. |  | 49 |
| 4217451258 | Intertidal Zones | The area that is above water at low tide and under water at high tide |  | 50 |
| 4217451259 | Coral Reefs | diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. |  | 51 |
| 4217451260 | Oceanic Pelagic Zone | Most of the ocean's waters far from shore, constantly mixed by ocean currents. |  | 52 |
| 4217451261 | Marine Benthic Zone | The ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers. Organisms living in this zone are called benthos |  | 53 |
| 4217451262 | Fundamental Niche | The full range of environmental conditions (biological and physical) under which an organism can exist. |  | 54 |
| 4217451263 | Realized Niche | The ecological role that an organism plays when constrained by the presence of other competing species in its environment | | 55 |
