Rainforest vs. Desert!
Transcript of Rainforest vs. Desert!
Climate in the rainforest
The climate in the rainforest is hot, humid, it has no dry season, and it's annual rainfall is 2104mm.
Climate in the desert
The climate in the desert is hot and dry. There's less than 250 mm of precipitation in a year.
Plants in the rainforest
Plants in the desert
There are tons of plant species in the rainforest but these are just a few: fan palms, buttress roots, lianas, strangler figs, banana trees, orchids, coffee bean trees, brazil nut trees, and poinsettia.
In the desert, plants go without water for years at a time. Some plants adapt and grow long roots to get water underground. Cacti store water in them. Rubbery skin helps to protect water from being evaporated. Desert plants can be hundreds of years old.
There are over 3000 freshwater species and more than 370 types of reptiles. The rainforest is one of the last places for jaguars, harpy eagles, and pink dolphins. It's home to tons of birds and butterflies, too.
In the desert camels can go without food or water. Many desert animals are nocturnal so they wait for the sun to go down before they hunt. The desert tortoise spends most of it's time underground.
Climate change: Warmer temperatures and less rainfall produce droughts. These droughts wither crops, dry up fisheries, cause forest fires. Also, hydro-power is now being used in Brazil to meet energy demands, but dams are being built that are getting in the way of endangered aqua animal
The temperature can easily get too hot for an organism to live (some too hot and some too cold). Wind can make sand storms which could bury animals/plants. Lack of sunlight near the poles could affect plant eating organisms life because plants can't grow as well with limited sunlight.

Parrots and toucans eat nuts and have strong beaks to crack open shells of nuts. Leaf cutter ants cut leaves into pieces, carry them to their nest, then bury the leaves with saliva from the ant which grows a fungus that only ants eat. Also, three toed sloths use camouflage to escape predators.
Bats, snakes, foxes, and skunks are nocturnal which makes it easier for them to hunt at night. Some animals make burrows so that they can escale the extreme temperatures. Reptiles have light coloration to reflect heat and for camouflage.
Symbiotic for rainforest
Symbiotic for desert!
Mutualism- sloth hair is grooved and lets algae grow easily on it which makes great camou for the sloth. Parisitism- parasitic wasps prey on fig wasps. Mutualism- monkey gets bananas which gives the banana tree more room to grow.
Mutualism- bee pollenates on a cactus and depends on it for food. Parisitsm- fleas live on bodies of coyotes and other animals. Commensalism- gopher snakes use abandoned rodent holes as their homes.
