VOCAB
study of the interactions that take place among organisms and their environment
Ecology
Herbivore
Biotic
complex network of many interconnected food chains and feeding relationships.
Food web
Give the definition for Producer
organism that makes its own food, autotroph
Give the definition of Organism
one of any living thing.
eats herbivores, omnivores, or other carnivores.
Carnivore
all the living organisms that live in an area and the nonliving features of their environment.
Population
chain showing how energy passes from one organism to the next.
Food chain
Give the definition for Consumer
organism that cannot make its own food, a heterotroph
Give the definition for Ecosystem/Biome
large geographic areas with similar climates and ecosystems. Includes Tundra, Desert, Tropical Rainforest, Temperate Rainforest, Grassland, Arctic Tundra, Temperate Deciduous Forest.
Give the definition of an Omnivore
Eats producers and consumers
non-living parts of ecosystem-air/water/soil/sun
Abiotic
shows the direction in which energy flows. As the amount of available energy decreases, the pyramid gets smaller. Each layer on a pyramid is called a ____ level. (There are two answers for this question, what is the vocab word that matches this definition and fill in the blank)
Energy pyramid ; Trophic
Give the definition of a Decomposer
consumes wastes and dead organisms
Give the definition for Habitat
place where an organism lives and that provides the types of food, shelter, moisture, and temperature needed for survival.
an animal that is hunted and caught for food. Prey is a consumer; it may be an herbivore, omnivore, or carnivore.
In an ecosystem, refers to the unique ways an organism survives, obtains food and shelter, and avoids danger.
Niche
Give the definition of Energy Flow
through an ecosystem--The transfer of energy from one organism to another through food webs.
largest number of individuals of a particular species that an ecosystem can support over time.
Describe Mutualism and tell the symbols used to describe what each organism gets out of the relationship for each type of interaction. (+ is positive, 0 is neutral, - is negative)
++ ; Both species benefit from the interaction
Give the definition for Parasitism and use the symbols to describe what each organism gets out of the relationship for each type of interaction.
+- ; one species benefits while the other is harmed in the interaction.
Give the definition for Commensalism. Use the symbols to describe what each organism gets out of the relationship for each type of interaction.
+0 ; one species benefits while the other gets nothing out of the interaction.
What is a Limiting Factor?
Anything that can limit the size of a population, including living and nonliving features of an ecosystem, such as predators or drought.
What is Symbiosis? Name the three types of Symbiosis.
Any close relationship between species, including mutualism, commensalism, and parasitism
