Primary succession isn’t likely to occur in the UK as there isn’t much bare rock left. Secondary succession is when an area that was once colonised by plants, then the plants are suddenly removed. For example in a forest fire, as a result of this succession has to start again. Secondary succession is much faster than primary succession and will reach climatic climax much sooner. This is because there will still be a lot nutrients and soil left behind from the previous ecosystem.
However seasoned wood should burn quickly because of its relative dryness. I found that white oak has an excelent rating for burning. It has a high heat yeild and the burn difficulty is easy. It is hard to split. It produces light smoke and no sparks.
b) Candelabra Tree (_______ ) 1. Seeds are harvested in vast amounts and edible 2. Large food source for animals in the Savanna c) Elephant Grass 1. Favorite food of _________________ 2. Also harvested and burned to be used in _______ _ Plants C. Plant Functions a) Plants in the Savanna regions are highly specialized to grow in this region during long periods of drought b) They have long tap roots that can reach the deep water table, thick bark to resist forest fires, trunks that can store water, and leaves that _______ off during the winter to conserve water.
The major problems with cotton are that the plantations require a lot of herbicides and pesticides, they use a lot fertilizer and they use up massive quantities of water. Hemp however makes a stronger material than cotton that can be grown in several different climates, requires no herbicides or pesticides, needs no fertilizers and would consume a lot less water. Because hemp is more durable then cotton I would throw away less cloths and I would reduce my methane as well as my nitrogen emissions. The growing, harvesting and production of hemp textiles create significantly less greenhouse gases then the cotton industry and would be a fast and easy alternative to
The process to create the paper does not involve releasing harmful toxins like tree paper processing does. The largest benefit of using hemp as paper is the fact that hemp can harvest in just four months after being planted. Trees can take tens to hundreds of years to be ready for harvest. The fact that deforestation due to tree paper processing destroys the habitats for thousands of animals also must be taken into consideration and adds to the list of reasons why hemp needs to be grown in the U.S. In addition to the use of hemp as paper, an equally valuable and environmentally friendly use of hemp is as a source of
What are Madagascar’s biomes? Discuss the major features of at least one of these biomes. Use the textbook for biome examples. From the map in chapter 6.1 of the text for this week it appears that Madagascar has 3 biomes, they include Tropical rain forest, tropical dry forest, and savannah. In the tropical rain forests, temperatures throughout the day are warm and rain occurs almost daily.
This is a less important human cause as it doesn’t affect how quickly water reaches the river. With large floods, no matter how well the rivers are dredged, it is still likely floods would occur. A physical cause of the Somerset level floods is that they occurred over winter months, but soil moisture recharge had already occurred in October. Any excess rainfall after October would be surplus and would not infiltrate. This was not helped by the fact there were 8 storms in just 2 months.Also, over 407 years there have been 4 major floods, the frequency being 101.5 years per flood.
The persuasive message is pretty simple. It is simple in the fact that rough skin can feel like a rough tree. It is also persuasive by stating if you use this product it
America’s Roots The Native Americans are the backbone for the American existence.Without the Native Americans, the Europeans would not have had the resources needed to be successful in America. The Native Americans played an essential role in America becoming a nation because they taught the colonists the necessary tools needed to live in America such as growing crops, understanding the terrain, and using hunting systems. To begin, the Native Americans learned how to grow their own crops. Growing crops was important because it provided a source of food. It also gave them the ability to teach others how to grow crops so they can live in America without starving.
Currently there are no signs that genetically engineered bacterial resistance to these deceases will be introduced in a commercial setting in the near future even though the clear results from laboratory and field studies show that genetically engineered strategies for virus resistance work effectively (Collinge, Lund & Thordal-Christiensen 2008). Genetically engineered trees for unfavorable or difficult geographic locations would be a help to the Canadian forestry industry as the Canadian climate is in many places far from ideal, albeit such a large geographic area. Examples of preliminary success to tolerate adverse conditions include poplars engineered with an enzyme from mammals for detoxification of trichloroethylene, and eucalyptus hybrids genetically designed to withstand and tolerate the cold (Whetten & Kellison
