Transcript of Desert
'Positive human impact : The humans come and take some animals to centers to care for them. Humans also plant cacti and that helps to give some animals nests.
Positive Human Impact
Positive things that humans do in the desert are build parks that preserves the desert and everything in it.
Positive Human Impacts.
'Negative human impact :
drought in water causes
water holes to dry up.
animal : lizard = reptile
with over 6000 species
found in the desert
Negative Human Impact
positive human impact
abiotic factor : rainfall = limited water
temperature has a little moisture and
deserts lack the insulating protection
of humidity and cloud cover soil is dry
making it hard for animals to survive
People have polluted the air of the desert biome. Also people have drilled for many fossil fuels, like oil. That caused the pollution.
Humans have done many things for the deserts such as The National Wild Life Federation. They protect the wild life and the desert environment. They take endangered species into captivity and that allows them to reproduce and increase the amount.They have also created reserved areas just for the animals so there is no harm done to them.
Negative Human Impacts
To help the desert you can reduce, reuse, recycle and instead of taking a car you should walk or ride a bike to where you are going
Negative human impact
An abiotic factor of the desert is soil because the type of soil determines what plants can grow. Location and evaporation influence the types of soil also.
Global warming can have a huge impact on plants and animals in the desert, so there for it is not easy for plants and animals to live in the desert
The negative human impacts of the desert are
Human activities such as driving over the sand creates destruction in some animals burrows.
With the drills looking for water and oil they create pollution in the air which can be harmful for animals.
A common Abiotic factor is Temperature.
some abiotic factors are rainfall, temperature the desert, soil, light and the average rainfall ranges from 2-4 cm annually
The average temperature is 100 degrees F
The temperature drops a lot at night to 25 degrees F. Impact- Causes some animals to die of dehydration and many animals have to scavenge during the night so they are not so hot all the time. Also the temperature can effect the plants because they won't have sunlight

they are yellow and rarely in the
dominant species .
Plant In The Desert
One plant that is in the desert is the agave plant. They store water in their leaves, stem, and roots. This helps keep the plant cool in the harsh heat of the desert days. Their roots help them quickly absorb water from rain.
Mutalism is two organisms benifit, an example is desert polination between a bee and a flower
Impact on environment
The temperatures are so hot it is hard for people and plants, and other living organisms to live in the desert.
Animal In the Desert
An animal in the desert is the big brown bat. It uses echo's to know where their prey is, and also to avoid thing's. They eat insects, they prefer beetles over others. They have a strong jaw to chew through them.
Spade foot toad
Symbiotic Relationship in the Desert
A flea on a kangaroo rat is an example of parasitism because the flea benefits from it sucking the blood from the kangaroo rat. The kangaroo rat does not benefit because it loses to much blood and dies.
The spade toad frog remains dormant or in a deep sleep. Far underground.They come awake when the raindrops fill the pond. The raindrops make the toad want to emerge, lay eggs, breed and feed to replenish their bodies. They do all of this before they bury themselves in the cooler ground.
The mesquite tree has long roots (can reach 60 feet underground) to get water from the table. The roots help get water during hot times. The tree will drop it's leaves during droughts. In order to stay alive during alive they may go to sleep or dormant it can get water.
Describing plant and animal
Predator and prey
Animal: African wild dog
Plant: mexican poppies
An example of Predator and prey is The desert coyote and the Pocket Mouse. This is an example of predator and prey because the Pocket mouse is the prey of the Desert Coyote and the The Desert Coyote is the predator of the Pocket Mouse.

The african wild dog is a wild dog found in
Africa , this dog has a patchy coat, large ears and a fluffy tail
This video helps to enhance our understanding in which it shows many facts about the desert biome and it gives us extra information on what some life is like in the desert.
ex: a worm
african wild dog
Big horns and cattle
Commensalism is when one organism benifits from another and the other organism is not effected by it. An example a hawk building a nest in a saguaro cactus
This is a species of poppy found in Mexico and is now widely spread across the world
