  •  
  • An ecosystem is made up of two parts, the biotope and the biocoenosis.
  • The biotope, or physical environment, includes all of the non-living things in an ecosystem, such as geographical relief, soil, light and temperature. 
  • The biocoenosis includes all the living things in an ecosystem, such as plants, animals and other organisms.
  •  In an ecosystem, we can classify the relationships between individual organisms.
  •  Food chains, food webs and trophic pyramids show how energy is transferred in an ecosystem. A food web contains all of the food chains within an ecosystem. Ecosystems recycle nutrients
  • Biomes are regions of the world with similar climates, animals and plants. An ecosystem is the relationship between living and non-living things in an environment.
  • The biosphere is all of the ecosystems of the Earth. It includes the oceans, the land, the atmosphere and all the living things on the planet. 
  • Forest biomes :
  • Temperate forests have cold winters, warm summers and rainfall throughout the year.
  • Taiga forests are in regions where 
  • the climate is colder and drier.
  • Rainforests have very warm, wet climates with precipitation all year round.
  • Grassland biomes:
  •  Prairies are large areas of grassland with a temperate climate, that are a transition zone between forest and desert biomes.
  • Savannahs are grassland biomes with a few trees.The climate is hot and dry, although there is rain during some parts of the year. 
  • Aquatic biomes: Freshwater Rivers, lakes, ponds and wetland ecosystems.
  • Marine biomes : Marine ecosystems contain salt water and can be deep or shallow, warm or cold.
  • Desert biomes Deserts are very hot and very dry.
  • Tundra biomes Tundra are flat, treeless regions of the Arctic, where the subsoil is permanently frozen.
  • Overpopulation: The global human population is now over 7 000 million.
  • Overconsumption: Today we use more water, energy and resources than ever before.
  • Pollution :  Energy production, agriculture, transport and manufacturing all create pollution. Harmful chemicals are sometimes released into the atmosphere and into rivers, lakes and seas.
