Desert biome

Food web:

This is a desert biome food web. Like every food web, it always begins with the sun. The sun gives energy to the producers. The producers in my food web are: velvet mesquite, cacti, brittle brush, and fluff grass. The producers are then consumed by the primary consumers, also known as the first level consumers. The primary consumers in my food web are: kangaroo rat, jack rabbit, millipedes, and tortoises. Though the millipede, in my web, is classified as a primary consumer it is also a decomposer. Millipedes eat dead leaves/ animal waste to get their energy. The primary consumers are then eaten by secondary consumers. My secondary consumers are: coyotes and owls. At the top of my food web is the owl, which is known as the tertiary consumers. Tertiary consumers are at the top, and they receive the least amount of enery because energy decreases as it goes up the food web.

how are humans affecting the environment?

you may think humans don't affect the desert biome much, but you'd be shocked at how much you actually do. if you've ever gone off roading in the desert you've already harmed it by possibly killing animals who blend into the dirt for safety. another affect we have is installing underground pipes, because they cause unstable surfaces and water runoff.the last example is military practice. the military has bases in the desert that could kill many plants and animals, however since most bases restrict public admission, lots of land is possibly saved from human harm.

velvet mesquite

the velvet mesquite is a producer, which means it uses its energy from the sun to make its own food. the velvet mesquite is a shrub like tree with low hanging branches. the velvet mesquite gets its name from the small pods that grow from its branches. the pods have a velvet like texture and contain seeds.


though my food web the millipede to be a primary consumer, the millipede is also classified as a decomposer, which means it breaks down dead material or waste. the desert millipede often snacks on dead plants.


in my food web the owl is the tertiary, or top level, consumer. the owl is a carnivore, which means it only eats meat. since the owl is at the top of the food web, it receives the least amount of energy. this is because energy lessens as it moves up the web
