1.1 ecosystems Flashcards
one organism
individual
Group of individuals of the same species
Population
all living organisms in an area
Community
all living and nonliving things in an area
Eco system
large area with similar climate conditions that determine plant and animal species there (e.g. tropical rainforest)
biome
organisms fighting over a resource like food or shelter; limits population size
Competition
One organism using another for energy source
Predation
Relationship that benefits both organisms (coral reef)
Mutualism
relationship that benefits one organism and doesn’t impact the other (birds nest in trees)
Commensalism
(plant eaters) eat plants for energy (giraffe and tree)
Herbivores
(carnivores) kill and eat pray for energy (Leopard and Giraffe)
True predators
use a host organism for energy, often without killing the host and often living inside the house (e.g. Mosquitoes, sea lamprey)
Parasites
lay eggs inside a host organism; eggs hatch and larvae eat host for energy (e.g. Parasitic wasps, bot fly)
Parasitoids
any close and long-term interaction between two organisms of different species
Symbiosis
What are examples of symbiotic relationships
mutualism (+/+), commensalism (+/o), parasitism (+/-)
reduces population size since there are fewer resources available and fewer organisms can survive
Competition
different species using the same resource in different ways to reduce competition
Resource partitioning
using resources at different times, such as wolves and coyotes hunting at different times (night vs day)
Temporal partitioning
using different areas of a shared habitat
Spatial partitioning
using different resources based on different evolved body features
Morphological partitioning
