animals must be uniquely suited to handle the harsh climate and terrain. Surprisingly, there are a number of different plants that can endure the long, brutal winters and short, fleeting summers of the taiga, and they range from large pines to tiny lichens, each serving a role in this amazing ecosystem. 1. Balsam Fir The Balsam Fir is a common site in the North America taiga, and it is a quintessential favorite for use as a Christmas tree. Their relatively short stature and branches that grow…

it has once seized on it, like a lichen on the rock. I wished sometimes to shake off all thought and feeling; but I learned that there was but one means to overcome the sensation of pain, and that was death—a state which I feared yet did not understand.” (Vol. II, Chap.

Explanations Animals 1.) Fiddler Crab-I knew that this animal was a fiddler crab because of its habitat. It lived in the mud in my back yard that is part of the intercostal.

Rose-I knew this was a rose…

life has travelled to space but it cannot survive there without the necessary induced conditions. Only lichen and mosses have survived the vacuum of space and UV radiations yet. Imagine if you could survive the space without these conditions! Tardigrade (Water Bear), a water dwelling, 8 legged, segmented micro-animal has survived the space without any protection. They are prevalent in mosses and lichen and have a lifespan of a year. Tardigrades were discovered by Johann August Ephiran George.…

The mushroom is the most common type of fungi. Fungus is a fascinating organism because it is neither a plant nor animal. In some instances it appears that it has characteristics from both. Most people use to think that mushrooms were close relatives to plants, however they are not producers. This simply means that they do not make their own food. They receive their nutrients from their surroundings. They are labeled as decomposers because they break down their food and return the nutrients to…

them their try uniqueness in both plants and animals. There are many abiotic and biotic factors that are located in this biome such as: oak, maple, hickory, sweet gum, and Mongolia trees along with lichen, ferns and shrubs. Some other…

Reflect on how you would support children working scientifically in primary science. The National Curriculum (2013) sets out the skills needed for a child to work scientifically at a primary level. These skills include observation, pattern seeking and identifying, classifying and grouping of different objects. Children must also use their developing scientific vocabulary to show their clear understanding of scientific concepts. Due to the fact that science plays such a huge part in the…
