JAKARI AND JAQUANS BIOMES PROJECT 9N 10/12/2021

• We will be explaining the dessert and many organisms that have been discovered there.
• A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life.

PANCAKE PRICKLY PEAR CACTUS

• This is one of the cactus found in the desert.
• An adaptation this plant has is they reduced their leaves to spines to reduce water loss.
• They tend to reach 2.5m tall.

BARREL CACTUS

• An adaptation of this plant is the larger spines keep away thirsty desert creatures.
• They tend to live 50-100 years.

SAGUARO CACTUS

• An adaptation is that cactus have thick,waxy skin to reduce loss of water and to reflect heat.
• Another adaption is, They have large fleshy stems to store water.
• They also have deep roots to which spread over a wild area.

HEDGEHOG CACTUS

• The crimson hedgehog cactus steams are closely packed together. , it can lose heat. They use the cool night temperatures to exchange oxygen and carbon dioxide.

THESE ARE ALL THE COOL DESSERT ANIMALS OF THE DESERT

DESERT IGUANA

• The iguana go under ground into shade if it’s to hot.
• A adaption they also use is camouflage to hide from predators.

RATTLESNAKES

• Rattle snakes are well equipped to colonize and survive in arid habitats.
• They have thick impermeable scales on there bodies.
• They defect water and urinate from a distance with there smell and taste

SCORPION

• They’re exoskeletons, hard body casting, and venom on stingers give them great protection in the desert.
• Also there low food and water needs allow them to survive in the harsheet evnviorments.
• Also They slow down theremetabolism, the processes that work together to keep them alive.

DESERT TORTOISE

• Desert tortoise are able to to burrow to escape heat.
• They can store water In they bladder.
• They can also tolerate high levels of urea in their blood to keep from losing mosisture through excess urinating.

AT NIGHT

• At night desert temperatures fall to an average of -3.9c and about 25 degrees Fahrenheit

DURING THE DAY

• During the day the desert temperature rise to an adverage 38c and about 25 Fahrenheit a little over 100F

PRECIPITATION

• Deserts get about 250 millimeters (10 inches) of rain per year—the least amount of rain of all of the biomes.

SEASONS

• There are four types of deserts: subtropical deserts are hot and dry year-round; coastal deserts have cool winters and warm summers; cold winter deserts have long, dry summers and low rainfall in the winter; polar deserts are cold year-round.

LOCATIONS

• Deserts are usually found in South Africa, California,Mexico and Australia.
• Cold deserts, occur in the basin and range area of Utah and Nevada and in parts of western Asia.

DESERT THREATS

• Global warming is increasing the incidence of drought, which dries up water holes
• Higher temperatures may produce an increasing number of wildfires that alter desert landscapes by eliminating slow-growing trees and shrubs and replacing them with fast-growing grasses.
• Another threat is overgrazing woody vegetation clearance argricultual expansion water diversion and extraction soil and water pollution land conversion due to industrial activity
