Definitions Flashcards
define ecology
study of organisms and how they interact with the environment around them
define abiotic and give an example of an abiotic factor
nonliving. examples = temperature, weather, rocks
define biotic and give an example of biotic factor
living: examples = plants, animals, fungi, bacteria
define habitat
the physical makeup/environment where an organism lives
define a niche
the role an organism plays in a community
biome
locations with similar climates and species
community
groups of different species interacting with each other in the same place at the same time
population
a group of individuals of the same species living in the same place at the same time
ecosystem
all of the organisms in a region & their interactions with the non-living environment
if organisms have overlapping niches, what is a likely outcome of their interaction
competition
what type of organism is capable of using and storing energy from the sun
autotrophs
how must hetertrophs obtain energy
consumr otjer organisms
how do omnivores obtain energy (give an example of an omnivore)
eat both plants and animals. examples = bears, eat twigs, berries & small animals
how do herbivores obtain energy (give an example of a herbivore)
eat plants. example = cows that graze on grass
how do carnivores obtain energy (give an example of a carnivore)
