define Ecology
is the study of interactions between living organisms and their environment
Define Population
Organisms is a group of individuals of the same species occupying a given area at a given time
Define Habitat
The place you are occupying the lab room is your habitat
Define Community
consists of all those populations of all species occupying a given area at a given time
Define Ecosystem
The combination of the community and it’s environment comprise an
define Producers
are autotrophic organisms such as most plants and a few microorganisms
Define Consumers
are heterotrophic organisms that
Define Trophic level
consumers are usually classified into feeding (trophic levels) by what they eat
Define Primary consumers
are herbivores animals that eat plant material
Define Secondary consumers
are organisms that eat primary consumers or other secondary consumers
Define Decomposers
include fungi most bacteria and some Protista that break down organic material into smaller molecules which are then recycled into the ecosystem
Define Herbivores
animals that eat plant material
Define Carnivores
eat primary consumers or other consumes
Define Omnivores
organisms that eat either producers or consumers
construct a food well
Producers: Grasses
Primary consumers: Rabbits (eats grass)
Secondary consumers: Foxes (eats rabbits)
tertiary consumers: Eagles (eats foxes)
Identify organism
determine the specific organism you are examining
What level is Producers
They are at the first trophic level.
Ex: plants - algae
What level is Primary Consumers
They are at the second trophic level.
ex: rabbit- deer
What level is Secondary Consumers:
They are at the third trophic level.
Ex: foxes - snakes
What level is Tertiary Consumers
They are at the fourth trophic level.
Ex: hawks - lions
Type 1 survivorship
Shows survivorship in early life
high survival rate for young
Type 2 survivorship
constant mortality rate throughout life
death is roughly constant regardless of age
Type 3 survivorship
high mortality early life
few individuals serving adulthoods
