100
the variety of species in an ecosystem
Biodiversity
100
An organism that uses sunlight to create its food
What is a producer (autotroph)
100
Disease, competition, and predation are all examples of what type of factors?
Density-dependent factors
100
Give an example of a pioneer species
lichen, mosses, some grasses
100
an organism that hunts, kills, and eats other organisms (thinks top of pyramid - ex. hawk or shark)
What is an apex predator
100
Living part of an ecosystem is called...
What is biotic?
100
Type of data that shows numbers
(Examples 2 meters, 40 seconds, 2 liters, and etc.)
Quantitative data
200
How much energy is in the secondary consumer level of this trophic pyramid?
200kcal (note: the unit you are given whether kcal or something else does not change the number)
200
An organism that feeds on dead and decaying animals
What are decomposers?
200
Plants use this process to turn light into chemical energy
What is photosynthesis?
200
Food chains that are interconnected/overlaps in a particular ecosystem
What is a food web?
200
Process following a disturbance where only bare rock is present
Primary succession
200
Two or more species make up a
Community
200
Air, water, humidity, wind, rocks and the Sun are all...
What are abiotic factors?
300
the maximum number of individuals of a particular species that an environment can support
carrying capacity
300
Identify the part of the graph labeled d
carrying capacity
300
What are some examples of decomposers?
bacteria, fungi, worms, ants, beetles, sow bugs
300
Examples of density-independent factors include?
Floods, hurricanes, drought, climate and seasonal extremes.
300
At the bottom of a trophic pyramid, what are those organisms called
What are producers (autotrophs)
300
What happens to the predator population when prey poulation increases
Increases
300
something that restricts the number of organisms that can live in an area.
What are limiting factors?
400
***DAILY DOUBLE***
Give an example of two species that show a parasitic symbiosis
Flea/Dog
Mistletoe/Mesquite
Leech/Fish
Tick/Human
Worms/Cats
400
On a trophic pyramid what is the organism that eats the producer (second level of the pyramid)
What are primary consumers?
400
Type of species that can annihilate ecosystems.
Invasive species
400
Type of species that when removed, the ecosystem enters a consequential trophic cascade, a failure that leads many species to extinction
Keystone species.
400
An animal that eats plants or other animals and does not make its own food.
What is a consumer or heterotroph
400
Intra-specific competition is competition between what?
Competition between animals of the SAME species
400
Draw an age structure that shows an expanding/growing population
Pyramid-shaped
500
The step within the scientific method that examines the data and is generally presented through graphs and models.
Analyzing data
500
Identify the type of growth.
exponential growth
500
What happens in the final stage of succession?
Trees are growing. Climax community is reached
500
The type of symbiosis when both species benefit each other.
Commensalism
500
The three types of population distribution are?
Random, clumped, and uniform
500
Difference between primary and secondary succession
Primary succession starts at bare rock
Secondary succession starts after a disturbance to an ecosystem.
500
3 examples that promote loss of biodiversity
Invasive species, deforestation, extreme climate change, habitat loss, pollution, hunting and poaching, acid acidification
