1.5 – Features of habitat

Research on the tundra

We looked up Planet Zork’s tundra habitat and we realised there were 2 kinds of tundras: the arctic tundra and alpine tundra. From what we know of Planet Zork, its habitat is an arctic tundra as it is not specifically on a high mountain.

Conditions of a tundra:

  • extremely low temperatures
  • little precipitation (<– geography)
  • simple vegetation with no deep root systems
  • limited drainage
  • short summers of 50-60 days
  • permanent layer of frozen soil (permafrost)
  • top layer of soil turns waterlogged in summer
  • slowly decaying layer of dead matter

Animals in the tundra are

  1. adapted to handle long, cold winters
  2. breed and raise young quickly in the summer
  3. Mammals and birds have additional insulation from fat
  4. Many hibernate during the winter because of scarcity of food.
  5. Or: Migrate south in the winter, like birds do.

Plants are

  1. short and group together to withstand strong winds, cold temperatures
  2. photosynthesize in low light conditions
  3. most reproduce asexually and quickly within the short summers
  4. roots run horizontally rather than vertically into the soil (due to permafrost)

This gave us a better idea of the conditions our organisms had to face. After a brief discussion, we decided that our microhabitat would be on a plain as its conditions are not as harsh as those on the mountains.

–> But our organisms would not have shelter in this way 😦

So, we decided to include a mountain with caves as their shelter. This list summarises the habitat layout and the abiotic factors in it.

Habitat

  • Plain (grassland)
  • Covered with short plants that are clustered together
  • A mountain with caves is located at the far end of the grassland

Influential abiotic factors

  • Temperature – Low
  • Seasons
  1. Winter – extremely low temp., long
  2. Summer – warmer temp., short
  • Wind – strong
  • Soil – permafrost present in winter, waterlogged in summer
  • Water – little rainfall
  • Light – little sunlight
