Description of abiotic and biotoc elements
ABIOTIC : Abiotic is a non living thing examples of non living things in the savanna desert is
WATER
DIRT
WIND
SAND
and WEATHER
BIOTIC : Biotic is a living thing such as plants , animals and insects
Animals
- Elephant
- Z b a
e
r
-Lion
Plants
-Acacia senegal

-Candelabra tree

-Jackalberry tree

-Umbrella thorn

-Acacia


-Whistling thorn

-Bermuda grass

-Baobabs

-Elephant grass
-Gazelle
-Wildebeest
-Hippo
- Giraffe
-Crocodile
-Cheetah
-Emu
The interactions between biotic and biotic
The interactions between biotic and biotic are preditors and prey here are some examples
predator prey

Cheetah Gazelle
Lion Wildebeest
Parasitic tick Rhino
Egret Parasitic tick
and more !
DID YOU KNOW !?!?!?!?!?
Did you know that parasitic ticks feed on rhinos flesh the ticks benifit for this . The rhino suffers but to save the rhino and the egret its self the egret eats the parasitic tick this time both the rhino and the egret benifit but the parasitic tick dies in the end. Happy ending right !!!!
<= These examples right here are some of the main preditor and prey examples but not all . There are sooo many more examples !
Here in the backround is a picture of a cheetah eating a gazelle
INTERACTIONS BETWEEN BIOTIC AND BIOTIC !
This subject is where i would like to bring up herbivores and omnivores
Herbivores are animals that only eat plants some examples of this is a zebra , hippo and elephants ( there are more )

part deux
Omnivores are animals that eat both animals and plants examples are rhinos there are more !
Rhino eating grass ( biotic ) =>

FOOD WEBS AND FOOD CHAINS !
Tertiary consumer T
he tertairy consumer is the consumer that eats the secondary comsumer and gains all the nutrients

secondary consumer
Is the consumer that eats the primary consumer and gains the nutrients and then loses them when it gets killed by the tertiary consumer
Primary consumer -
Is the consumer that eats the producer
Producer -E
ats the decomposer
Decomposer - D
ies first
The tertiary consumer - Lions and Hyena- eat Zebras and a Cheetah
Interactions between abiotic and abiotic
An example of interactions between abiotic and abiotic is when wind ( abiotic ) is really strong and makes sand fly ( abiotic ) everywere !
Interactions between abiotic and biotic
Interactions between biotic and abiotic is when animals drink water water is abiotic and animals are biotic
and
When animals need a certain climate example zebra ( biotic ) and weather ( abiotic )
EXAMPLES !

-H
erbivore:
organism that eats mainly plants. Examples: cows, impalas, warthogs, zebras
-
carnivore:
organism that eats meat. Examples: leopard, lion
-
Omnivore:
organism that eats a variety of organisms, including plants, animals, and fungi. Ex humans, aardvarks
- D
etritivores:
organisms that break down dead plant and animal Examples: bacteria, fungi, termites
-
Scavenger:
animal that eats dead or rotting animal flesh. Examples: vultures, hyenas
-
Insectivore
: organism that mostly eats insects. Example: Red-billed oxpecker

How much food does a zebra eat per day ?
a zebra eats constantly through out the day . 90 % of its diet is mainly grass . a zebra can eat about 20 pounds a day !
How much water does a zebra drink per day ?
zebras drink daily ... they can detect when there walking above water and when this happens they dig holes to get to the water.the water that they find is filtered by sand ! zebras drink 20 L at a time !
Whats the zebras ideal temperature ?
they cant live in the freazing cold like polar bears ! zebras live in hot temperatures
interesting facts
-----------------
males weigh up to 950 lb and females weigh up to 850 lb
they can live up to 25 years in the wild and 30 years protected
they barley ever travel when they do travel its to find food , water get away from predators and to breed
there more active during the day
The end thanks for listening !
even if it was boring
Secondary consumer -the secondary consumer which is a cheetah eats baboons zebras giraffes and gazelles
Primary consumer - primary consumers which are giraffes , zebras , and baboons eat grass and acacia trees
and producers ! - the producers are grass and acacia trees eat dung beetles and termites !
