My organsim's amazing adaptations and its habitat


      Adaptations of my organism:
      
\     Body
     It has a white body. This is to blend with the surroundings which is snow and that is white. This helps the plant not to be spotted easily by its predators. This adaptation is camouflage.I got this inspiration from polar bears which live in Antarctic areas where it is covered by snow that is white.

    The plant is round instead of being straight up as this helps the plant survive the cold temperature in the arctic tundra.  When it like a ball, it has a closed surface which is thick and this could withstand cold temperature.  
     
     Green leaves
     It has green spots where the leaves are. The leaves are small so as to minimize transpiration, as the plants need water to sustain life. 

     Black spots


  • It has black spots with hair.  The darkness of their flesh absorbs solar heat, and the hair helps to trap the heat and keep it close to the surface of the plant.
  •     The black spots also acts as distractor to the predators confusing the predators as they would think that these are eyes.
  •  Some of the black dots are used to store shoots and food so that when there is absence of sunlight and the plant could not photosynthesise, the food would be used.
  •  The black dots also act as traps for the predators. When flies and small insects are on the plant, the slippery white floor would lead them to the black dots that would open and the insects would be eaten.

     Wings   
     The plant has wings. This helps the plant fly a short distance when the predators chase them. Under the wings, there is nectar which gives off a good smell that attracts preys and when the preys come near the wings, the would be stuck on the sticky nectar and would also be dead as the nectar is poisonous. The plants through the black dots would then eat them. The nectar could cause allergies to human who touch it.

     Spores   
     There is a bent part in the wings where spore bags are found as this plant is a non-flowering plant. The force of the plant’s movement would disperse the spores when it vibrates.

     Roots    
     The plants have very short legs which act as roots and this cause them to be exposed more to the soil and as it is round, it is exposed to the ground even more. This is because of the lack of nutrients found in the soil. Also being close to the dark, warmth, absorbent soil helps to keep plants from freezing.

     Detachable Head     
     It has a black rounded tail with eyes. This is to absorb heat and to sense if any animal is nearing the plant and this would lead the plant to vibrate so that the predators would be frightened and would be chased away. This is also to fool animals that that is the head and if the tail is detachable thus even if the plants eat the head, it would not affect the plant. 



My Organism's habitat:    
     
     My organism is living in the which is known for its cold, desert-like conditionsThe tundra is the world's coldest and driest biomes. About 1/5 of the Earth is tundra. The word comes from a Finnish word and means 'treeless plain'. The main seasons in tundra are winter and summer. Spring and fall are only short periods between winter and summer. Winters in Tundra are very cold and long while summers last for a very short time. The average annual temperature is -18° F (-28° C). Nights can last for weeks when the sun barely rises during some months in the winter, and the temperature can drop to -94° F (-70° C). During the summer the sun shines almost 24 hours a day, which is why the Arctic is also called the Land of the Midnight Sun. Summer are usually warm. Temperatures can get up to 54° F (12° C), but it can get as cold as 37° F (3° C). Average summer temperatures range from 37° to 60°F (3° to 16°C). Rainfall may vary in different regions of the arctic. Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches). Soil is formed slowly. About a metre under the top layer of soil there is ground that is permanently frozen, called permafrostIn the very short summers, the top level of soil thaws just long enough for plants to grow and reproduce, then become dormant (hibernate) over winter. Since it can't sink into the ground, water from melting permafrost and snow forms lakes and marshes each summer. But the permafrost layer never thaws. Because of this, tundra plants do not have deep root systems. When water soaks the upper soil surface, bogs and ponds may form and provide moisture for plants and small life forms. The Arctic tundra is also a windy place and winds can blow between 30 to 60 miles (48 to 97 kilometers) per hour. Of the North American, Scandinavian and Russian tundras, the Scandinavian tundra is the warmest, with winter temperatures averaging 18°F (-8°C).

Final Organism and Reflection





Reflection:

I had a great experience and pleasure doing this Performance Task. Through this, I learn so much about Tundra, adaptations of organisms living in Arctic regions, food chains, food webs, interaction between different organisms in the same habitat and the most useful skill which is the force fitting.  I loved my organism and I loved working with it. After doing the PT, I became very close with my organism, as if it is my pet. This learning process was fun yet enriching. I have understood and learnt so much about Ecology. While doing the video and some parts of the project, teamwork was emphasized well and we got a great bonding between each other. This also helped me to understand others perspective, other organisms' adaptations and many new things. Not only did the interdependence of the organisms were well understood, but also the interdependence between each other in our group. 








Food Web

 The Orginal Food Web


Cerritulus productoremàMusca argentarusàVafer anguis
Cerritulus productoremàAquahemp lepusà Canis caudis
Cerritulus productoremàVafer anguisà Canis caudis
Cerritulus productoremàAquahemp lepusà Vafer anguis
Nanum herbisàMusca argentarusàVafer anguis
Nanum herbisà Vafer anguisà Canis caudis



At first, I thought that Musca argentarus is a decomposer so my first food web was like the one below. 
Then I cleared my doubt with y groupmate and found out that it is a plant decomposer. So I made changes to it.


Then i realized that Aquahump lepus is not eating Nanum herbis. This is how I have derived to my final food web. '
In this food web, my organism, Cerritulus productorem, is a producer therefore, I have no arrows pointing at me which means I am not eating anyone. Another producer would be, Nanum herbis.  Musca argentatus is a decomposer and herbivore and Aquahemp lepus is a herbivore. Vafer anguis is an omnivore and Canis caudis is a carnivore.
