Transcript of Science 10 - Biome Project
-whenever it rains, it will soak up it all up and expand
-has long roots, that are all very close to the surface (4-6 inches deep)
-leaves have evolved into spines, which protects them from animals and they provide shade that lowers their water loss
-short growing season, and a long dormancy.
-defenseless to the cold, frost and snow can kill them
-flowers are pollinated by bats Cactus Ferruginous Pygmy Owl Armadillo Lizard Coyote Desert Kangaroo Rat Consumer: Cactus Wren Creosote Bush The abiotic features of the desert are very important to its inhabitance they are the fine line sometimes deciding if a biotic creature would live or die. Abiotic also known as nonliving things, sculpt the desert as into how we know it. The main Abiotic feature is the Sun because without it the desert would be the opposite as how we know it, all living things depend on the sun and the sun is expecailly strong in the deserts mainly because of it proximity to the equator. Another big factor that shapes the desert is the sand in it is the ground you walk on and is all around, its what most of the organisms live in. Water and precipitation is another big factor found in the desert sometimes there is a lack of water and most of the year there is little precipitation but all organism need water to survive and for some the lack of water is and a challenge. Temperature is also a big abiotic factor in the desert it is known to be very hot making the landscape very dry. The landscape of the desert varies from place, from rolling hot sandy hills to flat dry land. Some other abiotic factors in the desert are the air, climate, longitude, latitude and soil. Biotic also known as living organisms that are found in Desert are very limited due to the abiotic factors in the desert and only a select few species are found and have the characteristics and qualifications to survive. A biotic organism that not only survives, but actually prospers in the desert is a camel Keystone Species Ironwood Tree The Ironwood tree is a keystone species because it provides a shaded sanctuary and it creates rich, fertile soil for many species of plants to flourish.Many small organisms live in and around these trees because of the seeds they produce. Birds and reptiles also live near them for the insects that live there. Organisms such as insects, birds, reptiles,coyotes, and small rodents use the tree to survive. By: Erik MacLennan, Carolina Hodgins, and Devin Hewett Rattlesnake A Hot Desert Climatograph Human Influence This is a map showing all the hot deserts around the world. There are deserts in every continent and take up over 1 fifth of the land on earth.
There is a Polar desert in Canada in the Arctic. Osoyoos B.C. can also be considered a desert, but it is not official. -nest and breed in cacti and small shrubs, but favour the chaparral plant because it can protect them and their young from predators ie) snakes
-can also live in a hole in a saguaro cactus that was already made from another animal.
-most of the water that they need is found in the things that they eat
-eat insects, like beetles, ants, grasshoppers and wasps, fruits, seeds, or lizards or a treefrog
-adapted their eating habits according to the time of day
-the size of the clutch (number of eggs laid) depends on the amount of food available (usually 4 to 5 eggs) Desert Energy pyramid Producers Herbivores Primary

mining in the area, off-roading, hunting, and ranching. #7 #9 #3 When people think of deserts, they often only think of hot deserts. There are actually three other kinds of deserts. The first is the Polar desert. The biggest desert in the world is actually a polar desery and it is found in Antarctica. The Arctic in Canada is a polar desert, but it can also be conidered part of the tundra. Polar Deserts FOOD WEB The Definition of a desert is "a landscape or region that receives an extremely low amount of precipitation, less than enough to support growth of most plants. Deserts receive less than 25cm of rain each year. The temperature shown above is the average throughout the day in a hot desert.

Thanks for listening! The second type is the Semi-Arid Desert.The major semi-arid deserts include the sagebrush of Utah, Montana and Great Basin. It also includes the Nearctic realm (North America, Newfoundland, Greenland, Russia, Europe, and northern Asia). The average temperatures range from 21-27° C. The third kind is the Coastal Desert. It is found in the west of the Sahara of North Africa. It occupies a narrow strip along the Atlantic coast. The temperature is usually warm. These activities can kill the wildlife and the environment they live in. Coastal Deserts #6 Adaptations: Adaptations: Semi-Arid Desert Abiotic features of a desert have a big influence on biotic organisms
Main abiotic in the desert is the sun because all life depends on it
The desert is a place where the availability of water is the major factor that determines what types of organisms that can live there.
Sand is big abiotic feature in the desert
Some main abiotic factors are water precipitation or lack of it, temperature, land scape, air, climate, longitude, latitude and soil.
The abiotic features shape the desert as we know it to be
Only a select few species are found and have the characteristics and qualifications to survive in the desert
A prime example of an animal that has adapted to the environment and conditions of a desert is a Camel
Deserts are a lot different from other biomes because of it variety of plants, trees and animals.
Desert kangaroo rat, it has adapted to the desert and it had the ability to live without water for an extended period of time.
A cactus is a good example of a plant surviving in the desert because it has adapted to store water for long times
All biotic things in the desert have adapted in some way to survive and they all are effected by the abiotic factors of it. #10 Desert Collage grasshopper What major abiotic factor seperates the desert from other biomes?
A: The temperature
B: The amount of precipitation
C: The change in wind direction often
D: The amount of sunlight JEOPARDY GAME true or false, some deserts can be
found in Canada... what is the worlds largest cold desert? to be called a desert, the area has to receive a low amount of this... name a way humans have
negatively affected desert biomes which producer(s) live in a desert? a)Ironwood tree
d)Douglas fir tree which of the following methods does a saguaro cactus use to adapt to its environment? a) soaks up water and stores it
b) grows short to avoid being uprooted
c) grows spines to fend off predators Which organism is a primary consumer of the desert?
C: Kangaroo rat
D: Bobcat approximately how much? Does a desert have less or more biodiversity than a tropical rainforest?
Bonus: And name a reason why.
