U3 Why are natural environments important to I and S

• Biome- Area or envrionment classified by the animals/Plants that lives there
• Terrestrial biome - Biomes that are land base and influenced by temperature and rainfall
• Aquatic biomes - Biomes with a habitat that are dominatd by water
• Freshwater biomes - Biome with less than 1% salt concentration in the water with two categories called "Lotic" and "Lentic"
• LOtic: flOwing water habitat such as rivers and streams

  Lentic: Still water such as lakes and ponds
• Marine biomes - Biome with more than 1% of salt concentration of water that are divided into 5 parts
• Values of Biomes

  1.Essential resources - Sources for human survival/development

  2.Food security - Habitats for food and plants which is he bases of our food supplies

  3.Health and well-being - Nature providing improvement of mental health. Medical plants provided for modern healthcare

  4.Cultural Heritage - Biomes are necessary to form the cultural identity and hertage for indigenour communities

  5.Climate Resilience - Builds resilience from natural disasters and climate change
• Some threats to biomes:

  • Illegal Wildlife trade - Animal extinction/Deterioration of a equilibrium in the ecosystem(reduced biodiversity)
  • Pollution of environment - Impact on human food/toxic soil
  • Deforestation - Increased greenhouse gas/habitat loss
  • Climate change - droughts/rising sea levels
• Trophic cascade - An ecosystem collapse that cause the deterioration of a balanced food web due to the reduction of the top predator
• poaching - Illegal taking of wildplants/animals of their parts
• Natural resources in DRC - White SAP, rubber, uranium, cobalt, copper, diamonds
• Maritime effect - Sea having a cooling/heating effect on land depending on the temperature of the water
• 1. Latitude: climate can differ from the latitude of the location, becomes more inhospitable as close to north or south.
  2. Distance from the sea:The maritime effect can cause the differeing climate for biomes
  3. Altitude - Higher the biome is located above sea level, the colder the temperature is.
  4. Ocean currents(movement of water) - Make the location have a more temperate climate than other areas of the same latitude.
• Biodiversity - The variety of different species of organisms in a particular area, making the ecosystem more resillient and balanced
• Type of biodiversity

  1. Ecosystem diversity
  2. Species diversity
  3. Genetic diversity
• keystone - specific species that supports the whole ecosystem and holds the environment together
• The biome with a high percipitation and low percipitation are most likely to be a grassland
• Capital of drc - Kinshasa
• Gauchos - A Nomadic Horsemen that worked in Argentina and Uruguay
• What are the two types of Aquatic biomes?

  Freshwater biome and Marine Biomes
