Symbiotic Relationships
Ecological relationship between two species in which each species gets a benefit from the interaction.
What is MUTUTALISM?
The study of how organisms interact with each other and their physical environment.
What is Ecology?
Organisms that make their own food either using light energy for photosynthesis or chemical energy for chemosynthesis. They are the start of EVERY food chain.
What is an Autotroph/Producer?
The gradual change in the species structure of a community over a period of time.
What is Ecological Succession?
The variety of living organisms in an area. This can be local or global.
What is Biodiversity?
Ecological relationship in which one species receives a benefit but the other species is not affected one way or the another.
What is COMMENSALISM?
A characteristic of life describing how living things can control their internal environment.
Ex: Body Temperature
What is Homeostasis?
Organisms that consume or eat other organisms to get chemical energy, as they cannot make their own.
Ex: All Animals
What is a Heterotroph/Consumer?
The colonization of land where there were no living things previously.
EX: New rock from lava flow
What is Primary Succession?
Organism that can take over the habitat of a native species. This organism will change the ecosystem through competition, predation parasitism and habitat change.
What is an Invasive Species?
Ecological relationship in which one organism benefits by harming another organism.
What is PARASITISM?
The living components in an environment.
EX: Plants, Animals, Fungi and Bacteria
What is Biotic?
Organisms that break down dead organisms and organic matter to obtain chemical energy. In the process, they recycle nutrients.
Ex: Fungi and Some Bacteria
What is a Decomposer?
The type of succession that removes the previous community.
What is Secondary Succession?
Can weaken native plant and animal populations if brought in by an invasive species.
What are Parasites?
Remora fish are small fish that make their niche by picking up the scraps that sharks leave behind while feeding. The shark makes no attempt to prey on the remora fish. What kind of relationship do these organisms have?
What is COMMENSALISM?
The non-living components in an environment are called Abiotic. Name THREE examples.
What are: Sunlight, Soil, Temperature, Precipitation and Nutrients (Nitrogen or Phosphorus)
The percent of energy stored as biomass that is passed from one trophic level to the next in an energy pyramid.
What is 10%?
The pioneer species in this type of succession is best known as Lichens. These Lichens grow on bare rock and can take hundreds of years to develop into a climax community.
What is Primary Succession?
Occurs near oceans, rivers and lakes when the amount of water can no longer be contained. This process can be part of a natural cycle, caused by heavy rain and can cause soil erosion.
What is Flooding?
Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs and humans. Tapeworms get food by eating the host's partly digested food, depriving the host of nutrients. What kind of relationship do these organisms have with their host?
What is PARASITISM?
A community of organisms and their environment made of biotic and abiotic factors.
What is an Ecosystem?
The energy pyramid is most commonly 4-5 layers. Name the FOUR most common layers (in order of energy flow) starting with Producer.
What is Producer - Primary Consumer - Secondary Consumer and Tertiary Consumer?
The pioneer species in this type of community can typically be called grasses. These grasses grow in bare soil and typically develop into a climax community in only 150+ years.
What is Secondary Succession?
Occurs when there is below-average precipitation in an area over months or years. The ecosystem can usually bounce back from this natural process, but the land will typically suffer from crop failure and live stock death due to water shortage.
What is Drought?
