DESERT BIOME

By Alejandro Vieyra

Biology pre-ap p.8


Desert climate:

little rain fall, high temperature,and are located in middle of Earth


herbivores- ostrich

carnivore- coyote

omnivore- lizard

detritovore- Earthworms

vascular plant- cactus

nonvascular plants- mushrooms

mutualistic relationship- ants and fungus

gymnosperm- gnetophytes

angiosperm- bryophytes

parasitic relationship- flea and coyote

comensalistic relationship- cactus and cactus


Populations include lizards, coyotes and rabbits

The carrying capacity is an enviroment's maximum population size of the species can do necessities available in enviroment

.The biome's climate is affected by the desert being hot and so a species needs to keep cool

.The geography affects it by making it close to the equator thus it's temperatue.

. What would happen if exponental growth occured in population id that it would make it harder for other species to compete for the same resources due to the limit and hotness causing death for other species


DEPENDENT FACTORS

weather

enviromental conditions


DENSITY FACTORS

predators

competition


Hardy Weinberg principle states that the allele and genotype will remain constant from generation to generation, in absence of other evolutuonary influences including mutations, gene flow, non-random mating, genetic drift and natural selection.

Part 2

Adaptions in plants in desert:

Stomata-to not lose a lot of water

Roots- Are bigger to absorb water from deep down due to harsh temperature and root hairs to protect itself from other things

Xylem- Is better than other plants outside of desert due to harsh temperature so it needs to transport this energy fast

Phloem- Reduced in size so that they reduced the surface area

Flowers- are camoflauged to suite the desert enviroment and protect itself

Cones- Reduce due to desert heat

Seeds- more durable to withstand the harsh desert landscape

Meristones- No major difference towards other plants outside of desert


TYPES OF PLANTS

Vascular- ferns

Nonvascular- phloem

Gymnosperm- ephedra

Angiosperm- cactus

Monocot- narrow leaf gayfeather

Dico- Bananna

Fruit- Coconut


All animals:

get food heterotrophic, are eukaryotic, quite an amount, sexually reproduce, adapted over heat and adapted over terrain due to color :)
