By: J. L. March‚ 28‚ 2013 The Tundra Biome There are two types of tundra ecosystems: the arctic tundra and the alpine tundra. The tundra biome has several unique characteristics. The climate is very cold there is little diversity‚ and a "short season of growth and reproduction occurs" (1). The Finnish word tunturia‚ which means treeless plain‚ was the inspiration for the words tundra (4). The formation‚ plants‚ and animals that are associated with this biome have several attributes that make

What does this say about the amount of energy retained by the ecosystem versus that which is in excess at the end of the growing or producing season? (10 pts) 5. What ecosystem would you expect to have the least biodiversity? The greatest biodiversity? (14 pts) 6. What connection or relationship between

Chapter 54 - Community Ecology Homework 1. Explain the differences between competition‚ predation‚ parasitism‚ mutualism‚ and commensalism and give an example of each. Competition- (–/– interaction) occurs when species compete for a resource in short supply example when an invasive species moves in it cause competition. Large insects defend feeding sites on cottonwood leaves by kicking and shoving smaller aphids from better sites. Predation- (+/– interaction) refers to an interaction in which

The preservation ethic is more relevant to me when an area of land has a delicate ecosystem that would likely be unable to adapt to human influence. Tennessee has many relevant examples of conservation and preservation ethics. Radnor Lake is one area where the conservation

ADVANTAGES OF BLACK SAND MINING : Sand has become a very important mineral for our society due to its many uses. It can be used for making concrete‚ filling roads‚ building sites‚ brick-making‚ making glass‚ sandpapers‚ reclamations‚ and etc. The advantage of black sand mining is that the black sand is the one of the raw materials that used in making a metal that we used in building different establishments and buildings and also our houses.

important to have biodiversity‚ Biodiversity boost ecosystems productivity. What is productivity? Well productivity is the effectiveness of productive effort; it is about how well people combine resources to produce goods and services. It is important to have productivity because it improves the environmental standards for many species of animals; this can increase a species population and allow that species to thrive. Biodiversity boost the ecosystem productivity where each species‚ no matter how big
