A great variety of plants and animals exist on earth.They are essential for the survival of mankind. Today ‚ a major threat to survival of these organisms is deforestation. We know that deforestation means clearing forests and using the land for other purposes. Trees in the forestare cut for procuring land for cultivation‚building houses and factories and making furniture or using wood as fuel.Some natural causesof deforestation are forest fires and severe droughts.

that we can measure. Intangible benefits are difficult to measure‚ but improve our quality of life. 1 Most trees in cities or communities are planted to p p provide beauty or y shade‚ which are two excellent reasons for their use. Woody plants also serve many other purposes‚ and it is often helpful to consider these other functions when selecting trees for the landscape. The benefits of trees can be grouped into four categories; social‚ community‚ environmental‚ and economic benefits

earliest African ancestor of the modern crocodile. Researchers believe that this reptile’s body was 25 to 35 feet long. I think this story was very interesting because there was a crocodile living on land and in water. The crocodile was also eating plants which is also another interesting thing because they only eat meat now. Sometthing that is very crazy and pretty unbeleivable is that my uncle in fact has 2 crocodiles in his basement that he keeps in a clear box‚ like something you would see at a

to deal with them. Many governments prohibit bringing foreign plants and animals into their countries without authorization; some even go so far as to disinfect landing planes and the shoe-bottoms of people on them. Informing / Educating Education is a powerful tool‚ and the more people know about biodiversity loss‚ the more they will be prepared to help slow it. Spreading the word about detrimental human effects on plants and animals can encourage people to change their ways and effect

resistance Possums‚ from populations with exposure to this vegetation‚ are particularly tolerant to fluoroacetate. However‚ the level of tolerance varies among the different populations of each species‚ depending on the degree to which the toxic plants were present in their microhabitat. The brush-tailed possum (T. vulpecula) from Western Australia was found to be nearly 150 times more resistant to fluoroacetate intoxication in vivo than the same species from South Australia. Both possums are

De-Extinction is one of the hottest topics in the science world currently and it tops the lists of conservation and genetic scientists alike for next big project. Though this could be a great way to learn of past species and finally see them for ourselves‚ at what cost is a species revived? The idea of bringing back an extinct species‚ such as some type of dinosaur‚ comes with many questions that most find to be debatable. Conflicts arise from every aspect of this “new” animal including how it is

African Savannas The African Savanna is one of the largest tropical grasslands in the world. Tropical grasslands are known to have 90-150 cm of rainfall every year‚ a large area filled with grass‚ and being warm year round with a dry and rainy period. The climate in an African Savanna can range from 68o to 86oF. There are two seasons that are dry and wet on the environment‚ the winter lasts from October to March. The dry climate is caused by the lack of precipitation which can result in droughts

many fertilizers‚ use less water‚ keep the air around you cleaner‚ provide shelter and food for wildlife etc. Invasive grass species are bad because for one they are obviously not native to the area and can colonize habitats and exclude the native plants. Did you know a Dandelion is an invasive species? Well it is it from Europe but can be commonly found growing in other parts of the world like our front lawn.The dandelion shows just how much we see invasive species around us and don’t realize it

wetlands. Most commonly was perhaps a native wetland plant by the name of Big Blue Stem. This plant grows narrow blades that stand up to six feet tall. Big Blue Stem enjoys moist soils and can easily be identified near the end of Wild Goose Woods- where the forest floor is always burdened by water. Alongside Big Blue Stem‚ I identified Indian Grass‚ Wool Grass‚ Porcupine Sedge‚ the Water Smartweed and the common water plantain. One plant I did not come across during my field work was the cattail

Protist- a protest is a eukaryote that is not a member of the plant‚ animal‚ or fungi kingdom b. compare the updated classification of protists with the older one. Recently the protest kingdom has been divided into six major clades. These new found clades relate some of the protists to animals and fungi. 2.What are the four major ways protists can move?
