apes 1.1

individual

one organism

population

group of individuals of same species

community

all living organism in an area

ecosystem

all living and nonliving things in an area

biome

large area with similar climate conditions that determine plant and animal species there

competition

organisms fighting over a resource like food or shelter- limits population size

predation

one organism using another for energy source (hunters

mutualism

relationship that benefits both (coral reef)

commensalism

relationship that benefits one organism but doesn't impact the other (birds nest in tree)

herbivores

(plant eaters)

true predators

(carnivores) kill and eat prey for energy

parasite

uses a host organism for energy; often doesn't kill host; lives inside (mosquitos

parasitoid

lay eggs inside a host organism;eggs hatch and larvae eat host organism (parasitic wasps)

symbiosis

living together; close and long term interaction between two organisms of different species

mutualism

++

commensalism

+0

parasitism

+-

mutualism parasitism and commensalism are all

symbiosis

competition

reduces population size

resource partitioning

different species using the same resource in different ways to reduce competition

temporal partitioning

using resources at different times (night vs day)

spatial partitioning

using different areas of a shared habitat (different length roots)

morphological partitioning

using different resources based on different evolved features

biotic

living

abiotic

nonliving

what is an example of mutualism

coral and algae

coral provides co2 and reef structure for algae

algae provide sugars for coral to use as energy
