Suppose there were a group of prairie dogs living on the Nebraska plains. You watch them burrow into the into the ground to avoid a circling hawk.
ECOSYSTEMWRITE THIS DOWN:
AN ECOSYSTEM IS ALL THE LIVING AND NONLIVING THINGS THAT INTERACT IN A PARTICULAR AREA.
A prairie dog can obtain food, water, shelter, and other things that it needs to live, grow and reproduces from its surroundings.
HABITATWRITE THIS DOWN:
A habitat is the place where an organism obtains food, water, shelter, and other things it needs to live, grow, and reproduce.
LET'S WATCH THIS VIDEO AND SEE WHAT YOU REMEMBER.
THE DIFFERENCE BETWEEN ABIOTIC AND BIOTIC FACTORS
BIOTIC FACTORSWRITE THIS DOWN:
BIOTIC FACTORS - THE LIVING PARTS OF AN ECOSYSTEM
REMEMBER THAT BIO means LIFE
Biography - writings about someone's life; Biology - the study of life
ABIOTIC FACTORSWRITE THIS DOWN:
Abiotic factors are the nonliving parts of an ecosystem.
In some cases the prefix "a" means "not" such as:
apolitical means "not political"
abiotic means "not living"
POPULATIONWRITE THIS DOWN:
ALL THE MEMBERS OF ONE SPECIES IN A PARTICULAR AREA ARE REFERRED TO AS A POPULATION.
You don't have to write this: All the prairie dogs on those Nebraska plains are a population. All the daisies in a field are a population. However, all the trees in a forest are NOT a population unless they are the same species (such as oak trees).
COMMUNITYWRITE THIS DOWN:
A COMMUNITY IS ALL THE DIFFERENT POPULATIONS THAT LIVE TOGETHER IN AN AREA.
You don't have to write this: For example, in a prairie the community could be all the prairie dogs, the hawks, the grass, the snakes, ferrets, and owls.
Levels of Organization in an EcosystemThe smallest unit of organization is a single organism, then a population, then a community, and finally the ecosystem which includes abiotic factors such as sunlight, water, and soil.
ECOLOGYWRITE THIS DOWN:
ECOLOGY - THE STUDY OF HOW LIVING THINGS INTERACT WITH EACH OTHER AND THEIR ENVIRONMENT
