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

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
![Page 23: is the scientific study of the interactions between organisms and their environment.](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697bffa1a28abf838cc0a3b/html5/thumbnails/23.jpg)
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

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.,

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
