apes unit 1

individual

one organism

population

group of individuals of same species

community

all living organisms

ecosystem

all living and nonliving things in a area (plants, animals, rocks, soil, water, air)

biome

the plants and animals found in a given region (determined by climate)

competition

organisms fighting over a resource like food or shelter; limits pop. size

--

predation

one organism using another for energy source (hunters, parasites, even herbivores)

+-

mutualism

relationship that benefits both organisms

++

commensalism

relationship that benefits one organism and doesn’t impact the other

+0

herbivores

eat plants for energy

true predators

kill and eat prey for energy

parasites

use a host organism for energy, often without killing the host and often living inside host

parasitoids

lays eggs inside a host organism; eggs hatch and larvae eat host for energy

symbiosis

any close and long term interaction between two organisms of different species

mutualism, commensalism, and parasitism

competition

reduces population size since there are fewer resources available and fewer organisms can survive

resource partitioning

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

temporal partitioning

using resource at different times, such as wolves and coyotes hunting at different times

spatial partitioning

using different areas of a shared habitat

morphological resource

using different resources based on different evolved body features

biome

area that shares a combination of avr, yearly temp and preciptiation

latitude

distance from eq, determines temperature and precipitation

nutrient availability

plants need soil nutrients to grow, so availability determines which plants can survive in a biome

shifting biomes

biomes shift in location on earth as climate changes
