Levels or organization
Give me an example of a community
Anything with 2 different organims
What is a biome
an area defined by the species/weather
What is succession
when an ecosystem changes (replaced by new plants and animals)
How much energy is lost between each level
90%
Define biodiversity
the amount/variety of organisms that live in an area
Give me an example of an ecosystem
an environment with abiotic and biotic factors
What two factors determine what plants and animals can live in a biome
temperature and rain
Define primary succession
no soil, slow
How much energy is transferred between trophic levels
10%
What is the difference between biotic and abiotic
abiotic = not alive, biotic = alive
What is the difference between an organism and population
Organism is just one species, while a population is multiple organisms
What fact did you need to know about savannahs
large herds of grazing animals
What is the pioneer species in primary succession
Lichens (and moss)
What happens to energy as you move up a food pyramid
it decreases
Consumers are
organisms that eat other organisms
All the trees in the forest is an example of a population true or false
false
What fact did you need to know about tundras
they have permafrost
What is a climax community
an ecosystem that has finished its succession
True or false, organisms lose all their energy as heat
false
Why is the loss of biodiversity a concern?
humans depend on biodiversity for food and oxygen
Give me one example of each level of organization
answers vary
What fact did you need to know about rain forests
organisms with special jobs to avoid competition
Why are the development of larger forests bad for smaller plants
There is less space available
On the board draw an energy pyramid AND show me how the energy decreases if the P.P. has 4567 joules of energy
4567, 456.7, 45.67, 4.567, .4567
P.P., P.C., S.C., T.C., Q.C.
A= water/soil
B = plants and animals
