Create an energy pyramid for a desert biome by dividing a triangle into sections and labeling the necessary parts. The project takes less than an hour to complete and requires only a piece of paper and a pencil.Continue Reading
Draw a large triangle. Divide it into four sections. Label the bottom level "primary producers" and the next level "primary consumers: herbivores." Write "secondary consumers: small carnivores" in the next section and "tertiary consumers: carnivores" in the highest section.
Place the plants found in a desert biome in the bottom level. These plants include the barrel cactus, saguaro cactus, soaptree yucca, ocotillo, Joshua tree, desert ironwood, creosote bush and brittle bush.
In the next level, write down all the primary consumers such as the jackrabbit, beetle, grasshopper, fringed lizard, California quail, kangaroo rat, desert tortoise and cactus mouse.
Add secondary consumers to the third level. The roadrunner, kit fox, scorpion, rattlesnake, red-tailed hawk and turkey vulture are found in this level.
Add the few tertiary consumers such as the eagle and owl. Tertiary consumers are rare in deserts because there are often not enough plants to sustain the top level of the energy pyramid.
A biomass pyramid is a graphical representation of the comparative masses of consumers and foods at different trophic levels. The name biomass pyramid comes from the fact that the information is represented in a pyramid form, with those lifeforms that have the highest energy capacity usually concentrated at the base.Full Answer >
A semi-arid desert biome is characterized by relatively long and dry summers, with minimal occurrence of rainfall during the winter season. In the United States, this particular region includes the sagebrush of the Great Basin, Utah and Montana.Full Answer >
Desert biomes are dry climates that receive less than 50 centimeters of rain each year. Desert biomes feature one of four habitats—arid deserts, semi-arid deserts, coastal deserts and cold deserts. The desert biome covers about 20 percent of the earth's surface.Full Answer >
One of the only decomposers that is able to survive in the desert is bacteria because they are tiny and can survive in the air. Other decomposers, such as millipedes, earth worms and beetles, also live in the desert, but they have a difficult time surviving because they depend on moist areas.Full Answer >
