is the scientific study of the interactions between organisms and their environment

is the part of the Earth, including air, land, surface rocks, and water, within which life occurs

is a natural unit consisting of all Biotic (living factors) in an area functioning together with all of the Abiotic (non-living physical factors)

Why???MAKE ENERGY (cellular respiration)

Abiotic vs Biotic

is the collection of inter-breeding organisms of a particular species

is a group of interacting organisms sharing an environment

Organisms that use the sun directly are referred to as producers

Examples: plants, trees, grass

Organisms that feed on the producers for their energy are referred to as

____________________________

Examples: cow, insects, deer, mushrooms

PLANT EATERS

Organisms that feed on the primary consumers for their energy are referred

to as

___________________________

Examples: penguins, tigers,

birds

ANIMAL/Meat EATERS

Organisms that feed on the secondary consumers for their energy are referred

to as

_____________________________

Examples: fox, hawk, tigers, frog, human

ANIMAL & PLANT EATERS

Organisms that feed on dead organic matter and recycle nutrients back to the

land are referred to as

_____________________________

Examples: Bacteria and

fungi

FOOD CHAIN

Shows the flow of energy from one

organism to the next and to the next and

to the next

Displays the feeding relationships between

species within an ecosystem

Display many interconnected

food chains because in most natural settings consumers are not limited to one source of

foodPractice

Grass

They eat grass and crickets

is a graphical representation

designed to show the biomass or

productivity at each trophic level in a given ecosystem

Biomass is a measure of the animal and plant life that is found in a given area

As you move UPUP the pyramid:

•The biomass decreases with each level

•The amount of energy decreases with each

level

•The organisms become more complex with each

level

Herbivore

OmnivoreCarnivoreHerbivoreProducer

commonly describes the close and often

long-term relationships/interact

ions between different biological

species

any relationship between

individuals of different species

where both individuals derive

a benefit

,

Coral reefs are the result of mutualisms between coral organisms and various types of algae that live inside them

An example would be a honey bee and a dandelion. The honey bee gets to eat the pollen from the flower. The dandelion uses the bee to spread its pollen to another flower.

goby fish lives together with shrimp

The shrimp digs and cleans up a burrow in the sand in which both the shrimp and the goby fish live. The shrimp is almost blind leaving it vulnerable to predators when

above ground. In case of danger the goby fish touches the shrimp with its tail to warn it. When that happens both the shrimp and

goby fish quickly retract into the burrow

a relationship between two

living organisms where one

benefits and the other is not significantly harmed or

helped.,

Clown Fish and Sea Anenome

A relationship is one in which one member of the

association benefits while

the other is harmed

almost all free-living animals are host to

one or more parasite

Animals and ticks
