A single living being. (i.e. a flower)
organism
The relationship where both organisms benefit
Mutualism
Eats plants and meat
Omnivore
What is at the 1st level of the pyramid?
Producers
Who came up with the idea of natural selection?
Charles Darwin
What is the difference between biotic and abiotic?
Biotic is all living and dead things
Abiotic is all the non-living things
Fleas and dogs would be an example of which type of relationship?
Parasitism
Makes their own food
Producer
What is the organism called that is at the tip of the energy pyramid?
Apex predator
What is the difference between primary and secondary succession?
Primary - starting from only rocks
Secondary - starting from soil
All the living and non-living factors working together in one area
Ecosystem
Relationship where one benefits and the other is harmed.
Parasitism
A singular pathway that shows the energy transfer between organisms
Food chain
Why are decomposers not actually on the energy pyramid?
They restart the system and don't have a set position where they will take place.
Natural selection
A group of similar ecosystems that have the same climate.
Biome
Relationship where one benefits and the other is unaffected
Commensalism
A network of pathways that show the energy transfer between organisms
Food web
Each level of the energy pyramid is called what? (This shows the position of the organism in the food chain.)
Trophic level
What two events can cause secondary succession?
Floods and forest fires
List the levels of ecological organization in order from smallest to largest.
Organism, population, community, ecosystem, biome, biosphere
The term for two organisms working together in an ecological relationship
Symbiotic relationship
Explain why a food web is more sustainable than a food chain.
When an organism gets removed from a food chain, the chain is destroyed. When an organism gets removed from a food web, the web can usually survive.
Draw a picture of the energy pyramid including these items: Producers, tertiary consumers, decomposers, primary consumers, secondary consumers, highest energy level, and lowest energy level.
Picture
What two events can cause primary succession to occur?
Volcanoes and Glacial scraping
