Terrestrial Ecoregion Deserts and Xeric Shrubland

food web

two types of interaction.

one nutrient cycle in the xeric shrubland.

-Scavengers eat many animals that are deceased and that includes some reptiles that may act dead like lizards.

-Foxes are omnivores, they can a ribbit or a plant growing from the dry soil.

describe the biotic system in this ecoregion and what plants or animals live there.

-The soil helps the producers grow, making the consumers eat the producers, then the secondary consumers come in and eat the primary consumer. Finally the decomposer takes over the secondary consumer and breaks down the body and nutrients, thus, helping the soil make more producers.

key stone species

-The key stone species of the xeric shrubland is the producers, beause without them, then the primary consumers will die off, making the food web smaller.

-The the biotic system is based upon the energy pyramid, with producers being consumed by the primary consumers and so on.

-Some animals like, fox, coyote, and many reptiles were made to live there.

-Reptiles are cold blooded and are considered secondary consumers so some of them have a nature blend to their surroundings.

How do humans interact with the ecoregion?

What are the other abiotic factors that affect the ecoregion?

-In the xeric shrubland many people visit for site seein, or hiking. The people want to see an adventure but they will need to know how to take care of themselves.

what are the threats that face this ecoregion?

-Carbon dioxide due to humans who site see in a vehicle cause the temperature to rise, making animals over heat and drying out plants.

-The soil type is sandy and/or brittle making autotroph life difficult.

in what ways does the geology affect the ecoregion?

-One of the threats faced by the xeric shrubland is a drought.

-It originates by natural causes due to the warming of the Earths surface.

-This is viewed as threats to the ecoregion because without any water for the animals to drink out of, then will die off. Also plants will not have any water needed to grow.

- If this area is damaged or destroyed then many animals/plants that we know will be extinct or endangered.

one thing being done to make the threats less severe.

geology of my region

-The lack of rain may cause some affect by not helping the plants grow, thus not letting the primary consumer feed off of the producers.

-Without any source of water, (also due to the lack of rain) the animals living in an area that is dry will make them dehydrated. The animals die off making the food web decrease.

-People have been putting forth money to help creat some man made ponds and a pipe that pumps water to the pond. Also people believe that keeping them in captivity will help them survive longer.

-They hope to achieve to help an ecosystem survive while making the animals comfortable.

-This will help the people in this area overall by making the ecoregion last longer for hiking and site seeing.

pictures

-This land area is hot during the day time, but can reach temperatures of below 50 degrees during the night.

-Plants with little water needed, thrive with pointed tips of the leaves.

-Animals such as rodents and reptiles with very little large mammals.
