The Desert        

The desert is extremely hot during the day and vary cold at night. The extreme temperature change makes it hard for plants to grow and animals to live.

Biotic and Abiotic

Biotic Factors:






Abiotic Factors:






Carrying Capacity/change in population

Carrying capacity is the limit of organisms of a species that a habitat can support.

Camels for example are herbivores, this means they only eat plants and since there are a limited amount of plants that can grow in the desert Camels do not have a lot of opportunity to find food. This would be a limiting factor. 

Limiting Factors

Limiting factor are things such as environmental conditions that limit the growth of an organism or a population in an ecosystem. An example would be if 30 meerkat's are  living in a space for 40 meerkat's but has only enough food and water for 30 meerkat's. The meerkat population would not be able to grow any larger because of this limiting factor.

Energy roles

Carnivore is a meat eating animal like a coyote. Coyote's would be an example of a consumer..

Blacktail jackrabbit is a herbivore and only eats plants.

Omnivore is an animal that eats mean and plants such as an armadillo.

A vulture is an example of a scavenger, an animal that eats dead plants and animals.

Energy roles


A producer in the desert is a plant. Plants are important to the food chain because they capture energy and when eaten give the animals that energy.. These plants receive their energy from the sun and water. Producers are important because without them consumers and decomposers could not survive. An example would be cactus, and agave plant.


A consumer is animals. When they eat other animals they get at least 10% of their energy from that animal. For omnivor's they also get their energy from eats plants. An example of a consumer would be rabbits, camels, and birds.


A decomposer breaks down dead plants and animals. Examples of these would be fungi, dung beatles and ants.

Food chain/ Food web

A food web is more realistic than a food chain because a food web consists of many other food chains. A food chain only follows one path as an animal find food.

If we were to remove snakes from the food web it would not change the hawk that much because there are other animals for the hawk to eat. If we remove plants from the food web it would affect omnivores and herbivores and would could cause animals

Tropic Levels

A pyramid shape shows that at the bottom the energy level is high and it looses energy as you get to the top..

Producers have more energy and as the predators get higher on the energy pyramid they only get a limited amount of energy from what they consume.


Water from the roots come onto the leaf. Whale glucose leaves the leaf to feed the plant.

            carbon dioxide enters the plant through the stomata which energy from the sun absorbed by chloroplast. Then oxygen is released into air through the stomata.

The chemical equation is: co2+ h2o + C6H12O6 +O2

The reactants products of the photosynthesis pathway.

the equation shows that carbon dioxide and water are used with light and energy to produce glucose sugar and oxygen gas.

where photosynthesis take place

photosynthesis takes place in the root of the plat.


A tropisms is when an organism changes or adjusts in response to an external stimulus like the sun, shade, water or soil. This plants roots are growing away from the soil and the plant is growing toward the sun. Tropisms help plants in the desert grow because of the sun the sun make plants move toward the sun and so it could reach toward water. and water helps by giving the plant the nutrients that it needs to survive in the desert.

decomposers are vital to the ecosystem because they can decompose all plants and animals all the way down to waste.

you can find maggots, flies, and birds they are the kind of decomposers that you could find in your ecosystem.


the importance of having adaptations is because they protect yourself from getting hurt and they can also help you do a lot of things like climbing, running, and a lot of other stuff.

The adaptations of a cactus is that when the weather becomes dry the cactus can hold water and they have spikes on them to prevent any animals to take the water from inside the cactus.

camels can go long distances without much water and their eyes are protected with their eyelashes and what is also interesting about them is that they can store water in their humps.

3. By placing an organism from the desert to a rainforest it would end up getting too much water because it is use to getting little to no water, if it would not die of that it would die form predators that it does not have a defense against because their aren't many predators from the desert.

Check your definition and example of limiting factors, add examples of producers and consumers in your ecosystem, and in general, make sure that you go back through each section of text and reread what you have written to ensure that it makes sense and grammar/spelling is correct. Also, don't forget to add steps 9 and 10; I'm assuming you're still working on it though! Good job so far.
