1.1 Ecosystems Flashcards
Individual and give example.
single organism, elk
Population and give example
a group of single species, heard of elk.
Community
all of the living organisms within a region.
Ecosystems
All living and non living things in an area.
Biome
Large area with similar climate conditions that determine the plants and animals that live there.
Competition
organisms fighting over a resource like food or shelter; limits population size.
Predation
one organism using another for energy source
hunters, parasites, even herbivores
Mutualism
relationship hat benefits both organisms
coral reefs
Symbiosis
any close and long-term interaction between two organisms of different species.
What are the three symbiotic relationships?
- mutualism
- commensalism
- Parasitism
Type of interaction that is (-/-)
competition
Types of relationship that is (+/-)
Predation and parasitism
Type of interaction that is (+,+)
Mutualism
Type of relationship that is (+/0)
commensalism
Herbivores
eat plants for energy
true predators
are carnivores, they kill and eat there pray for energy.
Parasites
use the host organism for energy often without killing the host and often living inside the host.
Parasitoids
lay the eggs inside a host organism; eggs than hatch and the larvae eat the host for the energy.
Way to reduce competition among species
Resource partitioning
What is resource partitioning?
different species using the same resource in diff. ways to reduce competition.
What is temporal partitioning?
occurs when competing species use the same resource at different times.
Spatial partitioning
occurs when competing species utilize the same resource by occupying different regions
Morphological Partitioning
occurs when two species have evolved slightly different structures to utilize the same resource.
