Transcript of Taiga Biome

Taiga Biome The most wonderful place on Earth. Organisms Relationships Competition Competition is a symbiotic relationship in which two organisms dispute for certain resources in their habitat. For example, in this video, the two geese are fighting over bread found in a local parking lot. Just watch to see what happens. Predation Predation is the symbiotic relationship in which a predator, hunts a prey and harms it. Mutualism Mutualism is the relationship when both organims benefit. Commensalism One organism
benefits, while the other is neither harmed nor helped. Parasitism Parasitism is when one organism benefits, while harming the other. C.H.N.O.P Carbon The Five Elements of Life. Hydrogen is a very essential element in water. Hydrogen Nitrogen is used by living organisms to make complex organic molecules such as amino acids, proteins, and nucleic acids. Nitrogen Oxygen Phosphorus Carbon is an element found in all organisms,fossil fuels,the ocean,soil,and the atmosphere. An important way that we take part in the carbon cycle, is by breathing CO2 in the air. Helps organisms to do cellular respiration, and helps to produce water. Phosphorus is a very important chemical for plants and animals.
Mainly part of DNA, different fats in cell membranes, bones, teeth, etc. ADAPTATIONS Plant Adaptation: Coniferous Trees
The needle-like leaves let them prevent transpiration and freezing.
Cone shaped to prevent snow piling on in them.
Contain larger amount of chlorophyll for photosynthesis. Animal Adaptation
Most animals turn white in the winter to camoflauge with the snow.
Hibernate in the winter to get ready for the short summers that they have.
They produce very thick and warm layers of fur or feathers to protect themselves from the cold. Human Involvement Hunting:
Animals such as bears,beavers, and lynxes get hunted for their thick fur which now unfortunately makes them endangered. Global Warming:
The animals are adapted to the cold winters, and depend mostly on snow for habitat.
The rise in temperature is slowly melting the snow in the taiga for most of the year.
Deforestation:
The great amount of evergreen trees lead to use of wood which is causing rapid deterioration Population Trends Exponential Growth:
Occurs when the individuals of a population reproduce at a constant rate.
Usually occurs for a short amount of time.
When a population has many resources, the population will multiply and the size will increase. (J-curve) Logistic Growth:
Most populations show this growth, because resources are limited.
Population grows fast, then slows or stops because it reaches its carrying capacity, which is the maximum number of individuals a population can support.
Data shown by S-curve. Come soon to experience the beauty of the largest biome in the world! The beautiful setting would make you never want to leave!
