biotic factors-
living factors in an ecosystem.

kangaroo rat - meerkat - pronghorn - spotted hyena - fennec fox - black tailed jackrabbit - caracal


buckhorn cholla - mormon tea - turpentine broom - blackbrush - big galleta grass - creosote bush- mojave yucca

aboitic factors-
non-living factors in an  ecosystem

dry air - little rainfall - intense sunlight - sand - gravel - covering clouds - humidity - hot temperatures

carrying capacity &                 changes in populations

The desert population changes over time because of the extremely hot climate, any other harmful animals, & harmful plants like cactus. They can very easily harm an animal.

limiting factors

If snakes don't get what they need to survive then the snake population will decrease & there will be more mice.

Also ,snakes eat mice, but if the mice doesn't get enough water or food & die, then the snake population will decrease.

energy roles

The producer gives the energy that all the other organisms need in the ecosystem.

energy roles in desert population are decomposers, consumers, producers.

food chains & food webs

Food webs in the desert ecosystem are more realistic than food chains, because a lot of the animals eat more than one organism or producer.

If you take away the insects, the frog & shrew population would decrease because they eat the insects.

energy pyramids

tropisms -
biological phenomenon, including growth or turning movement of a biological organism

turning or bending movement of an organism towards or away from the stimulus. (light,heat,or gravity)

examples of tropisms in my ecosystem are phototropism, hydrotropisms & many more!

The tropisms help the plants survive my providing sunlight & positions for the plants to live.


photosynethesis is make up of carbon dioxide , water & sunlight.

The products that are made in photosynethesis are glucose & oxygen , also know as sugar

photosynethesis goes through the chloroplast & inside the chloroplast is a green pigmont called chorlophyll.

the chemical formula is

C02+H20 ---> C6H1206+02


The decomposers ar every important in the desert ecosystem! They help make the sand, soil, & gravel.

If i didnt have the decomposers in my ecosystem, my ecosystem probaly wouldn't exist because it mostly depends on decomposers.

exaples of decomposers-

termites, yeast , beetles , fungi & ants.


An adaptation is to help an organism hide from their prey.

like a lizzard, it can camoflage to hide from its prey. (hawk)

In the desert organisms needs lots of adaptation because there arent much places to hide. unless you find a cave or moutian.

a good adaptation is to stay near water because it gets so hot & there isnt water all over the desert, it will be easier to survive.

in some deserts the soil is a litle moist, giving the organisms the oppertunity to get more water. But in really hot deserts there isnt as much water. So they will need to find a place to keep cool & have some water.

But most plants get water on a daily bases because of the soil. But if its a really hot & dry desert then the plants adapt to having to store water to stay alive.

Correct the doesn't to do not, and try to catch up on all steps need.( and see if there is and food web for your ecosytem )
