-Jackalberry Trees
-Bermuda Grass
-Umbrella Thorn Acacia


-Forest Fires
-2 Seasons, a wet one and a dry one
-Most of the time, above 70 degrees Fahrenheit
-During the dry season, very compact ground
-Sometimes floods in wet season
-Humid Air

Carrying Capacity: the number of people, other living organisms, or crops that an ecosystem can support without total destruction to the environment.

Elephants eat berries, grasses, and bark. If a forest fire was to occur one year, the elephants wouldn't have much food, water, or shelter. But, as the grasses grow back and it rains, in the next year, the needs of the elephants will be met.

Limiting Factors: an environmental condition that tends to limit population size or abundance.

-Forest Fires
-Lack of Water (during dry season)
***A predator/prey relationship in the savanna is the cheetah and the gazelle. If there was an extremely bad forest fire that burned a huge amount of grass, the gazelle wouldn't have food to eat. The gazelles would decrease in population; the cheetah wouldn't have the gazelle to eat.***

Energy Roles:

3rd Level Consumers: Lions and Cheetahs
2nd Level Consumers: Meerkat and Egyptian Mongoose
1st Level Consumers: Zebras, Impalas, and Warthogs
Producers: Acacia Tree, grasses, and Jackalberry Tree
-All of the energy roles get their energy to survive from the role below it.
-Producers create their own food by photosynthesis. If the sun didn't shine its solar energy on the producers, the producers would not be able to create their own food. If there were no producers, THERE WOULD BE NO LIFE.

Food Chains and Food Webs:

-Food chains are more realistic than food webs because food chains show ONLY ONE direction that the energy can go. But, in real life (in the savanna), the energy can be transferred in multiple different ways, hence a food web is more efficient and realistic.
-If you took away the lion from the food web, there would be an increase in the population of the warthog, zebra, and impala. During that increase, the grass and tree population would decrease because there would be more organisms eating the plants.

Trophic Levels and Energy Pyramids:

-Using the pyramid shape helps illustrate how much energy is being transferred from organism to organism.
-The producers are at the base because the producers thrive the most; the top predators are at the top because there is more competition to survive and there are fewer top predators.


-The three things needed for photosynthesis are sunlight, water, and carbon dioxide. Also, there are two things produced by photosynthesis: glucose and oxygen.
-The chemical formula for photosynthesis is:
                                                       6CO2 + 6H2O ------> C6H12O6 + 6O2
-In a chloroplast organelle of a plant is where photosynthesis takes place.


-Tropisms: directional movement responses that occur in response to an external stimulus.
-An example of a tropism in the savanna is the acacia tree. It has more dome-shaped leaves, which allow the tree's leaves to absorb more light (phototropism) due to the wider spread of leaves.
-With more light, the acacia tree can produce more glucose, to help the plant thrive in the savanna.

The Role of Decomposers:

-If there were no decomposers, the savanna would have dead carcasses laying around everywhere in a grassless field, with feces everywhere. Overall, the savanna would not exist without decomposers.
-Some decomposers in the savanna include bacteria, earthworms, and termites.


-Adaptations are very essential to an organism's survival. If a organisms didn't have adaptations, the chance of life on Earth would be very small.
-Physical adaptations, like thick paw pads or thorns, help protect the organism from danger, keep it safe, and help the organism get food, water, and shelter. For example, without a gazelle's long, thin legs and body, it wouldn't be able to run fast enough to avoid the predator.
-On the other hand, there is another type of adaptation. Behavioral adaptations also help the organism in the same ways, but these adaptations are not something you can see. Migration, hibernation, and some certain behaviors during mating season are behavioral adaptations.
-Some adaptations animals would need to survive in the savanna are: lighter-colored fur (camouflage), thick paw pads, speed, stealth, and thin fur.
-Some adaptations plants would need to survive the savanna include: longer roots, fewer leaves, small and thorny leaves, loosing leaves during dry season, and thick bark.

-If a cheetah was moved to the Arctic, he would be extremely cold (he has a thin coat), it would be rare to find food, because cheetahs can't swim like seals/penguins can. Also, it would be hard for the cheetah to find fresh water. Overall, the cheetah would freeze to death, starve to death, or die of dehydration.

Natural Selection:

-Natural selection is the gradual (slow, time-consuming) process by which traits become either more or less common in a population.

-Giraffes used to vary to be with either short or long legs. As time passed by, the shorter leg giraffes decreased in popularity because their short, stubby legs were a disadvantage when being chased by a predator. Now, there are only long-legged giraffes left.

Don't forget to include a predator/prey relationship for step 4! I love your pictures!

@fabianhernandez Thanks, but I thought the Mufasa meme was pretty funny. 😇
