Taiga Food Chain

The Taiga
By: Krish Patel
The Taiga
Also known as the boreal forest or the snow forest, the Taiga is the world largest biome that is characterized by forests consisting of pines, spruces, and larches.
Taiga
Fern
The fern is the most populated organism in the whole of the taiga biome. They are autotrophs, which mean they produce their own food (glucose) from the sun, water, and carbon dioxide through photosynthesis. The producers contain the most energy in an ecosystem. When consumed, it will lose 10% of its energy, the rest of its energy will go into the environment.
Producer
Squirrels
Squirrels are strictly herbivores and receive their energy from the ferns and other plants. They receive 10% of the ferns energy and when they are consumed, 10% of their energy goes to the secondary consumer They are the 2nd most populated level of organism in the taiga.
Primary Consumer
Snakes
Snakes are carnivores that rely on primary consumers like squirrels, which makes them heterotrophs. They receive 10% of the squirrels energy and will give off 10% to the tertiary consumers. They are the 3rd most populated level of organism in the taiga.
Secondary Consumer
Wolf
Wolves are the 4th most populated level of organisms in the taiga and prey on the secondary consumers of the taiga, which makes them heterotrophs. They receive 10% of the secondary consumers energy and the rest of the 90% goes into the environment and decomposers.
Tertiary Consumer
Obtaining Energy and Oxygen
The taiga wolf obtains its energy and food with its mouth, strong jaws, their 42 teeth, and tongue. They obtain oxygen through their nostrils and mouth.
Obtaining Food and Gases
Digestive System
Digestive System
After the wolf has chewed their food, it uses its saliva to help the food go down their esophagus and to the stomach. The stomach then uses chemicals and acids from the pancreas and liver to fully digest the food. The food then digests and absorbs with a substance called bile which is produced by the liver and stored in the gall bladder. The proteins and fats is then broken down by the small intestines. The large intestines gets the last of the nutrients from the food and then goes to the colon. The colon processes the food into waste and sets it for excretion. This waste is passed into the rectum and out the anus.
Matter and Waste Through the Consumer Cell
The heterotrophic cell of the wolf obtain energy and matter through aerobic and anaerobic respiration. Through aerobic respiration, glucose and oxygen is needed while anaerobic respiration needs glucose.
Consumer Cell
Matter and Waste Through the Mitochondria
Mitochondria
The mitochondria of a consumer cell produce energy by performing cellular respiration. This function uses glucose and oxygen to produce carbon dioxide (CO2), water (H2O), and 36ATP. The wolf receives oxygen when it inhales its lungs and carbon dioxide is released when its exhales its lungs. The cell receives the oxygen through the blood stream.
