1 00:00:00,430 --> 00:00:04,110 The ecosystem by 5th grade B. 2 00:00:08,759 --> 00:00:17,820 Savannah ecosystem. Grasslands are large areas of grass found in place with very little rain. 3 00:00:18,300 --> 00:00:23,980 Trees need a lot of rain to grow, which means that grass and small plants tend to grow instead. 4 00:00:24,440 --> 00:00:28,120 Savannas are found in tropical areas where there is more rain. 5 00:00:29,100 --> 00:00:33,380 For this reason, Germans see more trees, but not many. 6 00:00:33,380 --> 00:00:40,380 Aquatic ecosystem. Aquatic ecosystems can be marine and fresh water. 7 00:00:40,380 --> 00:00:43,380 Fresh water, water type, fresh water. 8 00:00:43,380 --> 00:00:46,380 Lakes, rivers, stems and ponds. 9 00:00:46,380 --> 00:00:50,380 Flora, bushes, roots and water lilies. 10 00:00:50,380 --> 00:00:54,380 Fauna, fish, cacodriles, turtles and frogs. 11 00:00:54,380 --> 00:01:01,380 Forest ecosystem. Rainy places allow trees to grow in large groups known as forests. 12 00:01:01,380 --> 00:01:06,379 Coniferous forests are located in the colder zones of the Northern Hemisphere. 13 00:01:06,379 --> 00:01:08,379 They are deciduous forests and tropical rainforests. 14 00:01:08,379 --> 00:01:12,379 Mediterranean forests are found near the Mediterranean Sea. 15 00:01:12,379 --> 00:01:20,379 The urban ecosystem. Instead of adapting to ecosystems, humans have adapted ecosystems to suit them. 16 00:01:20,379 --> 00:01:23,379 These are not as urban ecosystems. 17 00:01:23,379 --> 00:01:29,379 They have got many artificial elements, but also contain natural elements. 18 00:01:29,379 --> 00:01:34,379 Artificial elements include buildings, airpods, parks and bridges. 19 00:01:34,379 --> 00:01:37,379 And desert ecosystems. 20 00:01:37,379 --> 00:01:41,379 Deserts are the hottest and driest places on Earth. 21 00:01:41,379 --> 00:01:49,379 During the day, temperatures can reach up to 50 degrees, but drop to 0 degrees at night. 22 00:01:49,379 --> 00:01:56,379 Living things have adapted to the changes in temperature and the lack of water.
