Biotic and Abiotic Factors Flashcards
(18 cards)
What is a producer?
An organism that produces it’s own food. (e.g. bushes, sunflowers, dandelions)
What is a consumer?
An organism that cannot make it’s own food. (e.g. owls, pandas, wolves)
What is an omnivore?
An organism that eats plants and meat. (e.g. humans, ants, crows)
What is a herbivore?
An organism that only eats plants. (e.g. horses, elephants, tortoises)
What is a carnivore?
An organism that only eats meet. (e.g. tigers, crocodiles, eagles)
What is an autotroph?
An organism that produces it’s own food. (e.g. algae, grass, trees)
What is a heterotroph?
An organism that cannot make it’s own food. (e.g. cows, pigs, bears)
What is a decomposer?
An organism that feeds on dead/decaying organisms. (e.g. bacteria, mushrooms, mould)
What is a primary consumer?
An organism that feeds on producers. (e.g. deer, rabbits, caterpillars)
What is a secondary consumer?
An organism that feeds on primary consumers. (e.g. foxes, snakes, penguins)
What is a tertiary consumer?
An organism that feeds on secondary consumers. (e.g. lions, sharks, hawks)
What is the difference between a producer and an autotroph?
All autotrophs are producers, but not all produces are autotrophs.
What is the difference between a consumer and heterotroph?
All heterotrophs include not only consumers but also decomposers (heterotroph is the broader term)
What is a biotic factor?
Any living factor that affects another organism, or shapes the ecosystem in some way.
What are some examples of biotic factors?
-Predation
-Living processes
-Competition for resources
-Amount of disease
-Availability of food
What is an abiotic factor?
All non living factors of the environment that can affect organisms?
What are some examples of abiotic factors?
-Temperature
-Light intensity
-Co2 concentration
-pH of soil
What is trophic level 1 always?
A producer, where all the energy in the food chain comes from.
