Blog #7 Compare and contrast two biomes describe them in detail include pictures of plants and animals you are liklely to see
The two biomes that I will describe, compare, and contrast are the tropical rain forest and the tropical savanna.
The tropical rain forest are habitats to many animals or species. Rainforests contain lots of tall trees in a region of year round warmth. Rain falls 50 to 260 at average, inches a year; therefore, it is a wet climate group where it only covers 6% of Earth's land in the world but it gives us 40% of Earth's oxygen so don't you think we need more tropical rainforests since this world is producing more and more people. Every year it is humid because of all the rainfall; a tropical rainforest gets about 150 centimeter of rain every year. The rain comes from all the hot and wet weather. The hotter the air is, the more water vapor it can hold; therefore, causing a lot of rain. The climate is near the equator meaning that their is more direct sunlight hitting the land and sea causing the water to evaporate into the air and the warm air can hold lots and lots of water vapor.
Scientists estimated that more than half of the animals and plants in the world lives in these forests; it is their habitat. Above the forest floor, there forms a dense covering called a canopy; additionally in the seond layer of shorter trees and vines forms an understory. The organic matter that falles to the canopy decomposes quickly and the nutrients are recycled. Abiotic factors of a tropical rainforest are hot and wet yearlybut also round. In addition, the sils are thin and nutrient poor soils.
The dominant plants are broad-leaved evergreen trees with ferns, large woody vines, climbing plants, orchinds and bromeliads. However, the dominant wildlife contains herbivores such as sloths, tapirs, or capybareas; predators like jaguars, anyeaters, monkeys; birds such as toucans, parrots, and parakeets; insects such as buttterflies, ants and beetles; reptiles such as caymans, boa constrictors, and anacodas; piranhas and also other freshwater fishes. The geographic distribution are parts of South and Central America, Southeast Asia, certain parts of Africa, southern India, and northeastern Australia.
The other biome is the tropical savanna or it can be called tropical grassland. The tropical savanna has a similar weather as the tropical rainforest because the temperature is warm but there are seasonal rainfall, compact soil, and frequent fires set by lightning. However, the tropical savanna receives less seasonal rainfall than the tropical rainforests. Savannas are seen by the isolated trees thereare and small groves of trees and shrubs or bushes. Compact soils, fairly frequent fire, and the action of large animals such as rhinoceroses stop some savanna areas from turning it into a dry forest. During the summertime, there are lots of rain days; an average of fifteen to twenty-five inches of rain falls which gets really humid and hot . Every single day, the hot, humid air will rise off the ground and collide with cooler air above and eventually will turn into rain.
Most of the animals in savannas have long legs or wings to be able to go on long migrations. Some animals are predators such as lions, leopoards, cheetahs, hyenas, and jackals. There are also animals such as elephants, giraffes, antelopes, zebras, baboons, birds such as eagles, ostriches, weaver birds, and storks; insects such as termites. The dominant plants are mostly tall, perennial grasses and sometimes drought-tolerant and fire-resistant trees or shrubs. Almost every animal and plant help each other to keep the enviroment balanced.
Every year savannas are lost to the Sahara desert because of overgrazing and farming; people had started using these savannas as a place to graze their cattle and goastsl they don't move around and soon the grasses are completely eaten up. With no vegetation, savannas just turn into a desert, dry and a place where vegetables are spotted.
These savannas are in large parts of eastern Afirca, southern Brazil, and nothern Australia.
How are tropical rainforests and tropical savannas the same? They are similar because of the weather; these places both have warm temperatures; however, the weather is different because savannas are not humid, but tropical rainforests are. Therefore, animals that are mostly like on the grass or land running or using their legs are mainly those that live in the savannas because animals that live in the rainforests are usually animals that climb on trees or the sky because the place is easier to adapt for them. Plants are also different because savanna plants are spreaded all around everywhere, but rainforests are very close together. Rainforests and savannas are also found in both northeastern Australia.
Parasitism is a type of symbolic relationship between two species of plants or animals in which one benefits at the expense of the other and even sometimes, without killing it. In addition, one organism lives on or inside another organism and harms it. The host from the parasite that gets all or part of its nutrientional needs from the other organisms.An example of parasitism is a tick feeds ont he blood of its host and may carry certain diseases that might cause microoraganims to appear. 
Predation is an interaction in which one organism captures and feeds on another organism. The predator is an organism that does all the killing and eating work. The prey is a food organism. Like in the picture, lions are fierce animals and they are strong; therefore, you can see that they are even eating an ox for food. Even cheetahs aren't animals to hunt for lions, instead, it is vice versa where cheetahs hunt for lions because cheetahs are fast and they have sharp teeth and claws to catch animals easier. Their powerful legs also causes them to run faster after their prey or enemy. 
Mutualism causes both species to benefit from the relantionship. The biggest example is flowers. As shown in the picture, a bee pollunates the flower causing the flower to sprout and look beautiful; thus both species are happy of the ending. The flowers also provides the bee nectar as a source or food or pollen and the bee helps the flower to reproduce. 
In commensalism, one member of the association benefits and the other is neither helped no harmed. For instance, barnacles are small marine animals that often attach themselves to the whale's skin. Whales are not harmed from barnacles when they are sticked onto the whale's skin and yet the barnacles benefit from the whale's constant moving in the ocean. Another example is that if a bird makes a nest on a tree, the tree does not get affected in any way and yet the birds benefit from the tree by having a place to set their shelter on which is their nest. 
Last of all, competition occurs everywhere. To be specific, competitions take place when organisms of the same or different species attempt to use an ecological resource in the same place at the same time. Resource is defined as to any neccessar of life such as water, nutrients, light, food, or space. An example would be that birds that are stronger would be able to fight for food better especially in the sky like an eagle catching a jay bird. The eagle would win; therefore, also getting food to eat and fill up its stomach.
