sustainable biomes

Question 1

def of a biome

Answer 1

• a community of plants and animals that extend over a large area due to similarities of climate and elevation.

Question 2

biomes

Answer 2

• terrestrial(land based(
• aquatic(water based)
• Variations in the visible landscape and animals that have adapted to the climate
• BIOMES MOVE AS THE CLIMATE CHANGES
  -diversity and functional understanding= our survivl and wellbeing
• biomes have adapted to changing climates and human interference.
• biomes are practially a large group of similar ecosystems
• biomes have a similar weather, rainfall, animals and plants.

Question 3

what is a ecosystem

Answer 3

• an ecosystem includes all the living elements in each area, ineractin with each other and the non living environments.
• each organims has a role to play

Question 4

habitat

Answer 4

• specifically where a species of organism lives.

Question 5

influence of climate on biomes

Answer 5

• affects the location, climate and soil
  (soil -> flora and fauna)- bc of difference in temp and precipitation patterns
• productivity -> how many consumer species a biome can support
• extreme climate- low productivity, lor precipitation, poor soil quality

Question 6

how climate is influenced

Answer 6

• distance from equator(latitude)
• distance from the sea
• landforms surrounding
• elevation(altitude)
• ocean currents
• air movement

Question 7

latitude

Answer 7

• focus of rays on equator- curved earth- suns rays travel more spread out- sun does not heat up earth as effectively (why the poles are colder)
• influences rainfall and photosynthesis.

Question 8

altitude

Answer 8

• the higher up variations in the landscape, harsher climate, worse soil and low precipitation

Question 9

landforms

Answer 9

• mountain ranges affect amount of pre that reaches inland areas
• prevent moisturised winds form reaching inland areas (they create borders)

Question 10

ocean current

Answer 10

• continuous movement of ocean water that flows in oceans driven by gravity and wind

Question 11

ocean currents and air movements

Answer 11

• currents are generated through = earths rotation, wind, temp, salinity, diff of moon gravitation.
  -evaporation- increases temp and humidity -> rain and sand storms
  -cold ocean currents + warm land mass = cold ocean currents cool the air- less evaporation = drier areas- arid(desert)
• ## dry air + warm land( the water starts to heat up) = less likely to release moisture - arid areas.

Question 12

soil in biomes

Answer 12

• determines which plants and animals inhabit the area
• characteristics + productivity of the soil: temperature and precipitation
• rocks and minerals make up the bedrock which is the basis of soil development:
  altitude, soil and vegetation cover

Question 13

reasons for soil type and productivity

Answer 13

• biomes with higher temperature and rainfall = have more abundant soil
• erosion of bedrock -> more rapid and faster decomposing organic matter = more and nutricious soil
• this provides the biome with nutrients in a continuous cycle.
