Cold Tundra Biome

Dear Diary,

Today, I investigated the freezing cold tundra biome. The ones I’m investigating are the Arctic and Alpine. The Arctic extremely cold environment with barren landscape. The Arctic’s climate is cold and unforgiving. The average summer temperature is 3-12C, and the average winter temperature is -34 C. Its covering consists of a permanently frozen layer of subsoil, known are permafrost. The soil there is very saturated. As for precipitation, it usually gets 15-25 cm of rain. The Alpine Tundra regions are found on mountain at the high altitudes where trees are not able to grow. At night, it usually always gets below freezing. During summer, its temperatures rage between -12 to 10 C. The soil there is well drained. Precipitation there

The rainforest is one of the most diverse places on our planet, containing over half or the world’s animal and plant species. Furthermore, it produces 40% of the world’s oxygen. We humans are cutting down trees, killing all the animals and plant living there, and reducing the size of rainforest.

As the name implies, the rainforest, is indeed very rainy, receiving an average of 100 inches of rain per year. The temperature stays mostly consistent all year round, ranging from 20-34 C. In my stay, it was very hot and humid. The terrain is flat without mountains, but sometimes there will be hills. The ground is covered with dead leaves and decomposers. The animals and plants living in the rainforest are some of the beautiful, to the most lethal animals on earth. The Sumatra rhino is nocturnal, an adaptation for less competition. This species of rhino is endangered, and only 150 are alive today. Toucans had developed big, strong beaks in order to crack open the hard nuts of the rainforest. The Amazon Horned Frog has a near perfect camouflage. It looks exactly like a leaf to hide from its predators. The peacock plant has broad leaves help capture the limited light at the bottom on the rainforest. The devil’s Ivy has a drip tip to get rid of extra water. The Tualang tree has adapted a smooth bark to prevent animals from climbing it. The keystone species of the rainforest is the hummingbird. Without it, many plants would not survive, as the

I’m studying particular type of grassland known as the savanna. Savannas have a warm or hot climate. The rainfall there is concentrated within 6-8 months of the year, followed by dry season. Savannas usually receive 20-50 inches of rain throughout the year. If the rain was better distributed, it would become a tropical forest. The soil of the savanna is porous, with rapid drainage of water. It has a very thin layer of humus, which is organic soil made with decomposed animals and plants. It terrain is a flat grassland with scattered trees and occasional hills. The elephant of one of the most keystone species because it keeps vegetation at bay. When plant growth is high, the elephants will eat them. Elephants are able to make a woodland into an open grassland in a short period of time. Animals have adaptations to survive in the desert. The giraffe has extremely keen eyesight. Combined with its long neck, it can see predators from far away and hide from them. The zebra has distinctive black and white stripes to confuse incoming predators. Ostriches are very well adapted to speed. Powerful legs, flexible knees and supple, two-toed feet all contribute to its 44mph speed. It is the fastest animal on two legs. Plants have their own set of adaptations too! I got a rash from touching poison ivy. Poison ivy can cause a painful sting and can be very itchy. This is to protect itself from grazers are people. The Acacia tree has fire resistance
