and Judith Aldape The Gobi Desert Populations of the Gobi Table of Contents The Gobi Desert is located in south of Mongolia.
It is the second largest desert in the world. Where is the Gobi Desert Located? The Gobi's Biome Abiotic

Ephedra A Population is a group of the
same species. Gobi Desert Energy Pyramid ephedra wild garlic bindweed batis Gray wolf Population Increase The gray wolf population would increase
if they caught more prey and reproduced.
This would cause the decrease of herbivores.
It would also cause other populations that
depend on herbivores to decrease. Pretty soon
there would be no herbivores and if there are
no herbivores the plants in the Gobi desert
would increase because they wouldn't be eaten.
With only plants left the Gobi could not support
carnivores and soon there would be nothing but
plants. Limiting Factors One of the limiting factors for the Gobi desert are resources and space. Resources such as water can limit populations because plants need water in order to live. Depending on the amount of water there is a limit to the number of plants that can grow, which limits the amount of herbivores and omnivores there is in the Gobi desert. This limits the amount of carnivores. For example if there is a drought the original amount of plants will decrease. Space is a limiting factor because if there
is not enough space to fit all of the animals
and plants. Then there won't be as much
space and pretty soon the animals would
compete for territory and places to keep
there new born safe. Limiting factors are factors that limit the amount of a population. saxual Asiatic
Wild Donkey Bactracian Camel Gobi bear Goitered Gazelle Primary consumers Producers secondary consumers Tertiary consumers The energy in the producers is transferred to the primary consumers when they eat the producers.
However they only get part of the energy in a
plant because the plant uses the energy for its
own needs and stores the rest. The primary
consumers only get the amount of energy
stored by the plants so they have less energy. This also happens when the secondary consumers eat the primary consumers and when the tertiary consumers eat the secondary consumers and the primary consumers. Carrying capacity The carrying capacity is the amount of the population. that can be supported in a biome. For example the maximum number of Gobi bears there can be in the Gobi desert is 50. This is because there are very few plants that the Gobi bear needs to eat. This limits the amount of Gobi bears. Competition Competition is when 2 animals compete for resources such as water, food, and shelter. For example 2 carnivores (such as the gray wolf and the snow leopard) would fight over food,water, and shelter. Herbivores such as the musk oxen and the goitered gazelle would compete for the plants,water and shelter. Predator and Prey Predators are the animals that hunt animals
and the prey is the animals that are being hunted. Mutualism Parasitism Parasitism is a relationship
between 2 animals in which one benefits and the other is harmed. An example of parasitism in the Gobi desert is the mosquito which sucks on the blood of many animals in the Gobi desert. For example the mosquito sucks on the blood of the Takhi. The mosquito benefits because it gets food. The Takhi would be harmed because it would get diseases that the mosquitoes carry. Who's the predator?
Who's the prey? Jerboa's adaptation The long eared jerboa is uniquely adapted to live in the Gobi desert because its long ears help it keep cool when it's hot. It also stays in its burrow when it gets really cold . The long eared jerboa is a nocturnal animal which means that it sleeps during the day and comes out in the night. This is another way it beats the heat. Plant Adaptations Plants in the Gobi desert have adapted to their environment because the roots go deep into the earth so that they can get water. They have also adapted to their environment because they have roots that spread out over a large area to get water. Mosquito Animal Adaptations Animals have adapted in the Gobi desert because they are nocturnal which means that they only come out at night when it's cool to avoid the Gobi's high temperatures. Another way animals have managed to live in the Gobi is by being able to survive without water for a long period of time. Other animals such as the long eared jerboa have unique features that help them survive. The jerboa has long ears that help it cool off and long back legs that help it escape its predators. Human Impact We hurt the Gobi desert by holding races and marches because when we do that we damage or kill the plants from the environment. When that happens there is less plants for the herbivores to eat. When there is less plants there is less herbivores, when there are less herbivores there are less carnivores. In other words we decrease the number of plants and animals. Gold eagle tarantula Gray wolf snow leopard Takhi long eared
jerboa asiatic ibex Musk oxen plate tailed gecko marbled polecate The predator and prey relationship is about who eats who. For example the gold eagle eats the asiatic ibex. The gold eagle is the predator because it is the one who is hunting while the asiatic ibex is the prey because it is being eaten. Another example of the predator and prey of the Gobi is the Gray wolf who eats the Takhi. Commensalism Commensalism is the interaction of two things in which one benefits and the other is not harmed. An example of this is the plate tailed gecko with the saxual. The saxual offers the plate tailed gecko shelter to protect it from predators. the saxual does not benefit from this and it's not harmed. Mutualism is the interaction between two things in which both benefit. For instance in the Gobi desert the batracian camel interacts with the tarantula. The tarantula eats insects such as mosquitoes that will harm the camel. The camel is protected and the tarantula gets a meal.
