Transcript How do the geographic factors of a biome affect its organism?

What relationships
exist in an
ecosystem?
What are the relationships between
Alive or not alive
• Biotic
Living factors in the environment
Give me a example
• Abiotic
Nonliving factors in the environment
Give me a example
Habitat
The environment where an
organism lives
Niche
An organism’s way of life and its
relationships with its abiotic and
biotic environment
What do you call something that
is an individual and is biotic?
Species
The basic category of biological
classification, composed of
related individuals that resemble
one another, are able to breed
among themselves, but are not
able to breed with members of
another species.
What are the relationships
between species?
Symbiosis
• A close, long-term association
between two or more species
Are all Symbiosis relationships
the same?
No
Mutualism
• A symbiotic relationship in which
both organisms benefit
Commensalism
• A symbiotic relationship in which
one organism benefits and the
other is unaffected
Parasitism
A symbiotic relationship in which one
organism benefits while the other is
harmed
Coevolution
• Long-term changes that take
place in two species because of
their close interactions with one
another
Are there other relationships
between species?
Predator
An organism that eats other
organisms
Prey
An organism that is eaten by
another organism
Carnivore
A consumer that eats animals
Omnivore
A consumer that eats a variety of
organisms
Scavenger
An animal that feeds on the
bodies of dead animals
Herbivore
A consumer that eats plants
Host
a living animal or plant from which
a parasite obtains nutrition
Parasite
an organism that lives on or in an
organism of another species,
known as the host, from the body
of which it obtains nutriment
But, how do all relationships
work together to form a
ecosystem?
It starts with a population
Population
A group of individuals of the
same species that live together
in the same area at the same
time
Pick a fish tank and list a
population in the tank.
Community
All of the populations of different
species that live and interact in
an area
Using the same fish tank, list all
the populations of the community
in the tank.
Ecosystem
A community of organisms and
their nonliving environment
Using the same tank, list all the
biotic and abiotic in ecosystem.
How do the
geographic factors of
a biome affect its
organism?
What do you think?
• List all the geographic factors that you
think would affect the organisms in a
biome and how would it affect that
organism.
• Exchange your paper with the your
neighbor and add to your list.
Now, did you think of these factors
