what is ecology?
|
the study of interactions that take place between organisms and their environment
|
|
|
what does ecology explain?
|
how living organisms affect each other and the world they live in
|
|
|
what is a habitat?
|
the place a plant or animal lives
ex: ocean, tundra, grassland, etc.. |
|
|
what is a niche?
|
the roll the organism plays in its habitat; its total way of life
ex: food, shelters, survives |
|
|
what are abiotic factors?
|
nonliving parts of an organisms environment
ex: air, soil, temperature, water |
|
|
what are biotic factors?
|
all the living parts that inhabit an environment
|
|
|
all organisms depend on others directly or indirectly for food, shelter, reproduction, or protein
|
<- Fact
|
|
|
1st level of organization
|
organisms/ species: an individual living thing that is made up of cells, uses energy, reproduces, responds, grows & develops
|
|
|
2nd level of organization
|
population: A group of organisms, of all the same species, which interbreed and live in the same place at the same time
|
|
|
3rd level of organization
|
community: all the populations of different species that live in the same place at the same time
|
|
|
4th level of classification
|
ecosystem: populations of plants and animals that interact with each other in a given area with the abiotic components of that area
|
|
|
5th level of classification
|
biosphere: the portion of earth that supports life
-life is found in air, on land, and in water |
|
|
How does energy flow?
(what way) |
from the sun to the autotrophs to the heterotrophs
|
|
|
what are producers?
what are they also called? |
-organisms that can make food during photosynthesis .
-autotrophs |
|
|
what happens to most of the energy autotrophs produce?
|
they use most of it themselves and the rest is passed onto organisms that can't make their own energy.
|
|
|
what are consumers?
what are they also called? |
-organisms that can't make their own food
-heterotrophs |
|
|
what are the 5 types of consumers?
|
-herbivore (plants) -decomposers
-carnivore (tiger) (fungus) -omnivore (humans) -scavenger (crayfish) |
|
|
what can be shown in a food chain?
|
the transfer of energy from the sun to producer to primary consumers.
|
|
|
what is each step in a food chain called?
|
trophic level
|
|
|
what are the trophic levels?
|
1st-producer
2nd-consumer 3rd- consumer |
|
|
what are first order called?
what do they eat? who are they? |
primary consumers
eat other producers are herbivores |
|
|
is most of the energy the primary consumer gets used?
|
yes, only about 10% is available for another consumer
|
|
|
what is the 2nd order called?
what do they eat? |
secondary
consumers eat other consumers |
|
|
what happens to the energy at the secondary consumer
|
only about 1% is passed on to the third order consumer or tertiary consumer
|
|
|
what is the third order called?
what do they eat? |
tertiary consumers
eats consumers that already ate a consumer |
|
|
what happens to the energy
|
.1% can be passed on
|
|
|
what are preditors?
|
consumers that hunt and kill other consumers
|
|
|
what are prey?
|
animals that are hunted and killed
|
|
|
what are scavengers?
|
consumers that eat other dead consumers
|
|
|
what is another way of setting up the transfer of energy in an ecosystem?
|
energy pyramid
