Transcript of Endangered Animal
By: Sophia Kim and Hyeri Jeon
Symbiosis is a relationship between two or more organisms that live together or in a close association.
Adaptations is the change or an adjustment of an organism to better survive.
There are three types of adaptations:
Mutualism- a symbiotic relationship where two organisms benefit from each other.
Example in temperate forest:
Lichen is composed of fungus and algae. Algae produces chlorophyll and carbon dioxide from photo synthesis. On the other hand, fungus protects the algae from drying out by providing moisture.
Commensalism is a symbiotic relationship where one organism is benefited and the other is neither harmed nor helped.
Ex: opossum dens with the woodchuck in order to stay warm, but does not hurt the woodchuck.
Parasitism is a symbiotic relationship where one organism benefits and the other gets harmed.
Ex. Tape worms eating crops and human food.
Predation is a predator-prey relationship where a predator eats or eats part of the other organism. One organism benefits and the other gets harmed.
EX. Owl eating mice

Structural Adaptation is the physical feature of an organism which has a specific function. It increases the chance of survival for an organism.
EX. Fur on the black bears are a structural adaptation because it captures heat.
2. Fir tree has sharp needles, so it does not have snow piling up on top of it.
Primary Consumers: (in the food chain) an animal that feeds on plants; herbivore.
Ex) insects and small mammals: chipmunks, squirrels, and seed eating birds and larger animals such as deers and elks.
any green plant or any of various microorganisms that can convert light energy or chemical energy into organic matter.
Ex) fern, mosses, shrubs, vine maples, hemlock fir, spruce, and coniferous trees
(in the food chain) a carnivore that feeds only upon herbivores.
Ex) frogs, birds, weasels, racoons, owls and insects which live as parasites on other animals.
a carnivore at the topmost level in a food chain that feeds on other carnivores; an animal that feeds only secondary consumers.
Ex) lynx, wolf, bear, cougar
an organisms, usually a bacterium of fungus that break down the cells of dead plants and animals into simpler substances.
Ex) termites, leaf-cutter ants and smaller organisms such as slugs, fungi and bacteria.
Where it found on Earth
Spotted owl are an endangered species because the number of owls are decreasing every year. Two types of Spotted owls are on "The United States Fish and Wildlife Service Threatened and Endangered Species System.
Cutting down the trees and changing the habitat for the owls, due to cities make them endangered.
Also, the prey leaves the hunting area, leaving the owls to starve and eventually die off.
Spotted owls live on trees, so cutting down trees will make them homeless.
Physiological adaptation is a physical or chemical event that happen in an organism's body for better chance of survival.
EX. Wolves maintaining heat in winters.
2. Pine trees have a small surface area, so they don't lose water as fast.
If they want, they could roll their cones in, to lose even less moisture.
Temperature and Precipitation Pattern
Food Chain and Food Web
There is a large amount of precipitation in temperate rainforests, ranging from as low as 100mm~400mm.
Temperature is 5~ 15 degree Celsius all year round.
Climatograph of British Columbia
Climatograph of New Zealand
Temperate rainforests are located in mid-latitude areas of high rainfall, which are mountain ranges that are close to the coast.
Western North America
Southwestern South America
Types of animal species
Behavioural adaptation-how the organism survive in a unique conditions of its environment.
EX. geese migrate when it is time in order to survive.
2. Frangipani Plant moves its stem in order to face the sun like the sunflowers.
Most of the trees in the temperate rainforests of the Pacific Northwest are conifers such as the Douglas fir and the Redwood which is the tallest tree in the world.
Other trees are western hemlock, Sitka spruce, western red cedar, noble fir, and Pacific silver fir.
Small trees include big leaf maple, dogwood, and vine maple.
The others are blackberries, salmonberries, sword ferns, devil’s club, mushrooms, moss and lichens.
Types of vegetation
Small mammals are dominant.
Black bears Rabbits
Gray wolves Spotted Owls
Bob cats Bald Eagles
Elk Tree Frogs
The temperature in the Temperate Rainforest rarely drop below freezing during the winter, and irregularly exceed 80 degrees during the summer months.
High rainfall (minimum 2-3m/ year, depending on latitude).
It depends on the proximity to the ocean to moderate seasonal variations in temperature. It makes milder winters and cooler summers than continental-climate areas.
