Taiga Food Web
Transcript of Taiga Food Web
There are lots of rocks and trees in the taiga so the lichen clings on to them.
The bracken fern stores food in its stem to consume.
Grass had threadlike roots to absorb water and nutrients in the soil.
Caribou have broad hooves to support them in deep snow.
White Tailed Deer
The deer have a covering of hair that helps them keep warm in the winter.
Cotton Tailed Rabbit
They have good hearing and eyesight to stay alert.
Its long legs and broad hooves make the moose a strong swimmer and help it walk through deep snow.
Wolverines are small but they have learned how to kill prey by jumping up on them and pushing them down
The red fox has keen hearing and a excellent sense of smell so it can catch prey.
Large fur-covered paws serve as snowshoes and enable lynxes to move easily in deep snow.
The gray wolf has an excellent sense of vision, smell, and hearing.
The function of these decomposers is to break down the remains of dead organisms
Producers are organisms (such as plants) that makes its own food.
1st level consumers are herbivores or omnivores, they eat the producers.
2nd level consumers are carnivores or omnivores which eat the 1st level consumers and usually producers.
3rd level consumers are omnivores or carnivores which eat the 2nd level consumers.
Taiga Food Web!
1 foot to 2 feet tall and 6 inches to 1 foot wide
The bright blue berries attract animals to eat the fruit.
Protection From Weather/Climate:
The pine needles have a wax coating to keep the cold harsh weather out of the plant.
The fern can grow mostly anywhere and reproduction happens when animals eat the berries, then animal's waste puts the seeds in the ground.
The Berry-Fern has to compete for sunlight during the growing season and have to compete for space to grow.
The plant will provide food for the animals and because the berries are close to blueberies many animals will eat it.
My organism is small so that it can get around without being seen.
Food and Water:
The Bleleon eats lichen and bracken fern. To get the food and water it needs to survive my animals has a very good sense of smell so it can smell out his food.
Protection and Defense:
My organism has very good senses so the Bleleon is always alert.
Protection from weather and climate:
My organism has thick fur to keep it warm in the Taiga.
My organism lives in a small burrow, the adaptations it has to make these burrows is claws for digging.
My animal will supply food for the 3rd level consumers in it's ecosystems.
My organism might eliminate some plants because it has a big variety of producers and it eats eats a lot of each producer.
Effect on Ecosystem
In the Taiga, winters are cold with average temperatures below freezing. There are at least 6 months of winter in the taiga. Summers are short with pleasant temperatures.
The taiga gets 12-33 inches of precipitation a year.
In Taiga the ground is more liquid then solid and much of the taiga is forest. There are some small lakes and bogs in taiga which are the sources of water for the organisms living in this Biome.
Effects on this Biome:
People use the taiga trees to get wood for floors, furniture, pulpwood, railroad tiles, telephone poles, musical instruments, and resin.
To conserve the resources in this Biome, people have created the Taiga Rescue Network and now many parts of the taiga are protected parks. People help by making parts of the taiga parts. People harm this ecosystem by cutting down trees, mining, and causing acid rain to fall.
1. In the winter soil depth can be 50 centimeters deep and 20 degrees Celsius (36 degrees Fahrenheit) warmer then the air above.
2. Taiga trees can endure conditions as harsh as the dessert because the trees can not use the frozen water during winter to grow.
3. The soil is very thin is the taiga because glaciers thousands of years ago scrapped away all the soil and it is very hard for the ecosystem to make more.
4. The taiga soil is very acidic because of the dead pine neddles droping from the trees not giving the soil any nutrients and there for is acidic.
5. Although two major cities Toronto and Moscow are located in the taiga biome most of it is uninhabited by people.
6. Fires are very common and necessary in the taiga to get rid of old and sick trees.
7. Scientists believe that the taiga was completely covered in glaciers many years ago.
B: The taiga forests are endangered due to to logging and mining by humans. Once the trees are cut down it takes a long time to replace themselves because of the short growing seasons
Water and Food:
To get water the fern soaks up all the melted water in the warmer soil.
