Vacuole
as one organism changes and adapts to its surrounding so others must change to survive
convolution
a physical or behavioral change to an organism to help it better fit its enviorment (happens throughout generations)
Adaptation
body structured that allows an organism ti better survive in its environment
physical adaptations
the ability to look like somthing else for better survival
Mimicry
to blend in with your surroundings
Camouflage
changes to an organism’s biology that allows it to better defend itself
chemical defense
bright or contrasting colors to warn other organism of toxins
warning colors
instinctive or learned functions of organisms to better survive
behavioral adaptations
when animals travel/move from one place to another due to seasonal changes
migration
organisms conserving energy to survive winter months with harsh weather conditions and lack of food
hibernation
organisma convering energy/ going dormant in the summer mounths to survive hot dry periods
estivation
behaviors to attract a mate, this looks different for every species
courtship rituals
the interaction between two different organisms living in close physcal areas/ enviorments
Symbiosis
both benefit from interactions
Mutualism
one organism is benefited from the interactuion and one is not impacted
Commensalism
one organism is harmed and other organism benefits
Parasitiam
where an animal lives. provides conditions to eat, shelter, and space to survive
habitat
the role an organism (or population) plays in an ecosystem
Niche
an organism that is not native to a particular area. harm the inviorment.
invasive species
what are the impacts or invasive species?
reduce biodiversity
increased competition
economy and industry
main energy source for food chains and webs
make their food using sunlight (photosynthesis)
producers
eat/ hunt for food
consumers
what is the order of consumers starting at who eats the producer
primary consumer
secondary consumer
tertiary consumer
eat both plants and animals
omnivores
only eat meat
carnivores
only eat plants
herbivores
show the linear flow transfer of energy through an ecosystem
food chain
made up of all the living things in an ecosystem, through muliple connecting food chains
food web
organisms gain __ % of the energy they eat
10
what are the 6 levels of erganization in an ecosystem starting at most general
biosphere
biome
ecosystem
community
population
organism
(big bens exited costemers pant oreos)
the layer of the earth where life exists
biosphere
a large region characterized by a specific clamate and certain types of plants and animals
biome
the living thing and non-living things need each other to survive
ecosystem
group of the same species living together in a common area
population
an individual animal, plant or fungi
organism
a group of organisms that share the same genes and can reproduce fertile offspring
species
what are the two types of biome?
terrestrial (land)
aquatic (freshwater or marine)
what are biome determined by?
climate
(temperature and precipitation)
equator, most veraiety of species diversity, lacks seasons, hot
Tropical Rainforest
lots of trees, northern hemisphere, warm summer, cold winter
Temperate Forest (Deciduous)
Interior of continets, mountains, moderate rain, few trees
grasslands
northern hemisphere, little percipitation, coniferous trees denslt packed
Taiga (coniferous forest)
dominated by grasses, longer summers, shorter winters
Savannah
mediteranean climate, moderste temperatures, quick frowing shrubs
chaparral (scrub biome)
scattered vegetation. less than 30cm of rain a year
Desert
northern arctic regions, permafrost
Tundra
water with no salt, sharped by abiotic factors
Freshwater
largest biome, supply of nutrients
Marine
