Transcript of Tropical Grasslands/Savannas

Rhinoceros -Mammal
-Bilateral Body Symmetry Eagle -Birds
-Bilateral Body Symmetry
-Heterotroph Beak Type of an Eagle -large and powerful beak, used for catching and tearing prey items. The beak is heavy, yellow, and hooked Eastern Fox Snake -Reptiles
-Bilateral Symmetry TROPICAL GRASSLAND/SAVANNAS Raegan Cobb, Catie Colley, Hope Gosdin Camouflage The cheetah has blonde fur with black spots to mimic light and shadows of grasses Mimicy Snakes in the savannas such as the one to the left looks like a rattle snake so no one with mess with it. Migration Plants Native To Biome -Bermuda Grass -Candelabra Tree -Elephant Grass Animals Native To Biome Egyptian Mongoose Chacma Baboon African Wild Dog Problem that affects biome -Extremely Cold weather could kill the plants and animals
-Animals would not know to hibernate and they would freeze during the cold weather
-Plants are very dry and would get too wet and die Carbon Cycle Flow The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth predator - prey Nitrogen Cycle flow The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. Lions hunt warthogs The carbon cycle is the cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Water Cycle Flow There are no sponges in the Savannas because there
are not any oceans. Oxygen Flow Cycle The water cycle, also
known as the H2O cycle,
the continuous
movement of water on,
above and below the surface
of the Earth. Climate Change •Continued global warming could turn current marginal
grasslands into deserts as rainfall patterns change
-Density independent No animals hibernate in the savannas because the weather does not get cold enough. Zebras migrate for food to
Maasai Mar Beetle -Arthropods
-Bilateral Symmetry
-Heterotroph There are no echinoderms in the savannas because there is not any salt water. Echinoderms need salt water Abiotic Factors The average day during the winter-dry season is cool, but never gets cold. The summer-rainy season is humid and very wet Autotrophs/Heterotroph -Autotrophs: -WEATHER <<<
-Exhaust from cars excelerates global warming, which affects the climate Decomposers -Maggots help break down decayed animals -Density dependent The oxygen cycle is the cycle that describes the movement of oxygen within the atmosphere (air), the total content of biological matter within the biosphere (the global sum of all ecosystems), and the lithosphere Diseases -Rift Valley Fever
-Mosquito borne disease
-Affects domestic ruminants (cattle, sheep, goats)
-Density dependent -animals such as zebras
and elephants depend on
autotrophs for
nutrients and energy -Heterotrophs: -Without heterotrophs there to eat some plants, plants would over-grow and kill out other plants Natural Disasters -Frequent fires
-Able to survive fires because they grow from the bottom instead of the top
-Density Independent Parasitism -The ants hollow out the thorns and use them as shelter
-The ants protect the tree from herbivores and remove competing vegetation -Bullhorn acacia trees and certain species of ants. Mutualism -Ticks/fleas on animals
-The tick/fleas benefits by getting nourishment from the blood, but the animal is harmed Commensalism -The hyena and vulture benefit from a lion kill and interact with lions but have little effect on the lions' survival chances Biotic -Trees are biotic
-Trees provide shade and homes for many animals Worms -Earthworms
-Bilateral body symmetry Fish -Blue Sucker fish
-Bilateral body symmetry -The savanna experiences recurrent episodes of drought lasting 4-8 months out of the year. During the "dry spell," plant activities—growing, dying, decomposing—continue, but at vastly reduced rates
-The primary water recruitment strategy of savanna tree species is to maintain an extensive root system, designed to harvest water over a broad area.
