Adaptations to A Desert Biome

|[pic] |

a) The different organisms that can be found in a desert biome are plants, insects, reptiles, rodents, birds, spiders and some mammals. Most are cold blooded.

b) A) Snakes: are cold blooded, legless reptiles, very closely related to lizards; have long flexible scaly skin, have lungs, heart, and liver. Most of their organs are repositioned, reduced or removed due to their long bodies. They’re suitable for this environment because they’re cold blooded and can adjust to the temperature.

B) The organs of spiders are heart, aorta, venom gland, fang, brain, stomach, secum, malphigian tubules, silk gland, ovary (female), nerve cord, pedipalp, cloacal chamber, spinneret, trachea, lungs, and legs.

c) P) plants

C) insects, spiders, rodents, lizards, snakes, scorpions,

D) fox, hawk

d) Herbivores: insects

Carnivores: fox, snakes, lizards, spiders, scorpions

Omnivores: hawk, rodents

e) 1) insects

2) plants

3) spiders, scorpions, lizards, rodents, hawks

4) Insects usually come out at night when it’s cooler and they’re able to go without water for longer periods.

f) A desert is a landscape that receives less than 250mm of

precipitation a year. Their most common hazard is

dehydration, frostbite, and hypothermia.
