This document describes several terrestrial and aquatic ecosystems. Terrestrial ecosystems discussed include tundra, grasslands, forests, and deserts. Tundra is very cold and dry with lichens, mosses, grasses, and animals like reindeer. Grasslands are dominated by grasses and support animals such as elephants and zebras. Forests include coniferous, deciduous, Mediterranean, and tropical rainforests with different plant and animal species. Deserts are the hottest, driest places with cacti and small bushes and animals like lizards and snakes. Aquatic ecosystems discussed are lakes, rivers, oceans, coral reefs, shorelines, and the open ocean for marine environments and rivers,
