Day 8- Food Web and Energy Pyramid

Day 8

     Today I learned about a general food web of the desert biome.  I was able to also see some of these animals in action and I noticed there were cacti almost everywhere.  The primary producers include cacti, creosote bushes, thorn acacias, annual flowers, rabbit brush, ocotillo, and the sage brush.  The primary consumers, or plant eaters, are insects, rodents, kangaroo rats, and lizards.  The small predators, carnivores, and insectivores in the desert include scorpions, larger lizards, snakes, and tarantulas.  Finally, the largest predators of the desert are the hawks and foxes.  I posted a picture of the desert food web below.

I also have a picture of an energy and biomass pyramid of a desert.  The producers include the Whisk Fern, Mesquite Tree, and the Saguaro Cactus.  Some primary consumers include the Mule Deer, Black-Tailed Jackrabbit, Turkey Vulture, and Giant Desert Centipede.  Secondary consumers in this pyramid include the Desert Pocket Mouse, Western Diamondback Rattlesnake, and the Red Tailed Hawk.  Finally, the tertiary consumer or top predator of this pyramid is the Desert Coyote.  As you can see in the pyramid,  energy decreases 10% at each trophic level starting from 100% with the producers.

Hope these diagrams helped increase your knowledge of the desert biome!  Have a good night.

Day 5 🌵-Plants & Adaptations

Image
Hey blog,  Today was my 5th day in the desert. My tour guide took me to see the plants of the desert. I was surprised to see this plant life because I thought the desert was too hot to support life. The first plant I saw was a cactus.  This cactus was 10 feet and 100 years old but I learned that cacti can grow up to 20 feet two and live for over 200 years! The type of cactus I saw was a Giant Saguaro cactus, which has adapted to the harsh conditions of the desert biome. It’s shallow roots enable this type of cactus to soak up rain and dew before it evaporates, which is helpful because the evaporation typically overtakes precipitation in the desert. The cacti in the desert also have a spongy interior which allows them to expand and hold a lot of water. I also learned that cacti grow slowly to conserve energy.

Hello Blog! For the last time, sadly... 😥 Throughout my travels in the desert, I learned so much about the biome’s summer and winter climate, competition that occurs in the desert, different symbiotic relationships, limiting factors, animals and plants of the desert along with useful adaptations, human impacts on the desert, the water cycle, the nitrogen cycle, and I got to study a food web and energy pyramid!  I hope you learned about all of these aspects of the desert biome also and found these facts interesting and useful.  If you would like to research some of these things even more, here are the sources that I used when furthering my knowledge about organisms and different things that I saw while traveling the desert.  I’m going to miss the desert, but tune back to my blog when I travel to my next biome.  Next up is the rainforest!

Day 3- Competition

Image
Dear Blog, This is Day 3 of my travel blog.  Today during my journey around the desert I spotted four different sets of species competing against each other for some sort of prize.  It seemed as if these species were competing for resources.  The first competition I noticed was between the desert coyote and the sidewinder rattlesnake species.  Both animals were fighting over food such as the pocket mouse.  They were also fighting over water, since water is very scarce in the desert.  This specific scenario exemplifies interspecific competition, which occurs when members of different species occupy the same niche and have to compete for their needed recourse or materials. Desert Coyote  Sidewinder Rattlesnake eating Pocket Mouse  Desert Pocket Mouse  The second species competition was the red tail hawk verses the diamondback rattlesnake.  Both animals fight to the death for food in order to survive. This competition is also considered to be an example o
