ecology
the study of how living things interact with each other and their environment
ecosystems
consists of abiotic and biotic factors in an area
ecologists
are the scientists who study the interactions between biotic and abiotic factors
biotic
factors of the living parts of an ecosystem
abiotic
factors of the nonliving parts of an ecosystem
humans, animals, trees, plants, bacteria, fungi
five biotic factors
sunlight, soil, water, air, climat
five abiotic factors
deciduous forests, desert, grassland, tundra, rainforest
list six major ecosystems or biomes
deciduous forest
an ecosystem that loses leaves each Fall
rainforests
an ecosystem with very warm temperatures and heavy rainfall
rainforests
an ecosystem with thousands of different organisms
grasslands, savannah
an ecosytem with elephants, giraffes and zebras
pond
a freshwater ecosystem with cattails, water lilies, snails, insects, frogs, turtles, and fish
tundra
an ecosystem with very cold temperatures, polar bears, artic foxes, permafrost, and treeless
desert
an ecosystem that is sandy, rocky, very little precipitation, with cacti
water
needed for all organisms to live
producer
organisms that use energy from the sun to make their food
photosynthesis
the process to make their own food
plants
are most producers
algae, seaweed
producer of the ocean
consumers
organisms that get energy by eating other organisms
herbivores, carnivores, omnivores
three types of consumers
herbivore
a consumer that eats only plants
carnivore
a consumer that eats only other animals
omnivore
a consumer that eats plants and animals
decomposers
organisms that get energy by breaking down nutrients in dead organisms
omnivores
pigs, bears, raccoons are examples
herbivores
zebras, elephants, and giraffes are examples
decomposers
fungi and bacteria are examples
omnivores
humans are examples
producers
grasses, shrubs and trees are examples
carnivores
sharks, lions, wolves, hawks are examples
scavengers
carnivores that eat dead animals
decomposers
termites and earthworms are examples
scavengers
vultures, croes, hyenas are examples
decomposers
organisms that return nutrients back to the soil
population
a group of organisms of the same species living in the same place
community
all the population that live in the same area
community
the populations of frogs, mosquitoes, cattails all make up a pond
deer, wolves, ticks
name three populations of the deciduous forest
habitat
the place where an animal lives
true
True or False - A forest ecosystem can support the life of various organisms
niche
an organism's lifestyle
night, day
part of an owl's niche is to hunt when and while other animals hunt when
food, shelter
when organisms occupy the same niche, they compete for what resourses
decrease or die
the weaker population may
sunlight, water, soil, climate, air
list five abiotic factors of an ecosystem
sun
main source of energy for all living things on earth
location, nearness to water
affects temperature of an area
environments
where organisms with special adaptiation can live
cactus, camel, arctic fox
two examples of organisms with special adaptations
predator
an organism that eats other organisms in order to live
predator
the hunter
prey
organism eaten
prey
the hunted
camouflage, talons
two adaptations that help predators or prey
parasite
organisms that live in other organisms to get energy
host
the organism that is fed off of
loses energy
why is the hosted harmed by the parasite
parasites
fleas, ticks, leeches, tapeworms, and mistletoe
food chain
shows the path of energy from one organism to the next
food web
several connected food chains
one organsim
food webs show how organisms don't just eat
pollution
an unwanted change in the environment
cut down trees, pollute
list ways that humans change the environment
water
the most important nutrient on earth
water
without this, life on earth would be impossible
carbon
all living things ae made of this, which moves through the environment and living things in a continuous cycle.
carbon
photosynthesis and respiration are part of this cycle
nitrogen
bacteria and decomposers convert this gas into a form organisms can use to build proteins and perform bodily functions
rainforest
monkeys, toucans, and parrots make up what ecosystem
biome
an ecosystem with its own climate, soil, plants, and animals
endangered
an animal that may become extinct
extinct
animals that no longer exist
decomposer
the last link of all food chains
producer
first link of all food chains
consumer
the second link of all food chains
habitat loss, reduction
likely consequence of cutting down rain forest
decrease in population
may decrease the sunlight in an ecosystem
competition
this reduces when different organisms eat various types of organisms within the ecosystem
