Essays on Abiotic

Abstract

The ecological settings in an ecosystem change from time to time. The changes in the ecological settings are brought about by a plethora of factors. Through evolution, the organisms that live in the ecosystem also change to adapt to the aforementioned ecological changes. The adaptation of the organisms to the ecological changes yields variations because different organisms and even organisms of the same species are exposed to the elements to different levels. Man has a significant role to play in the ecological changes. Through his economic activities, the effect on ecosystems has been both positive and negative. Urbanization as ...

Literature on the effect of environmental stress caused by changes in the climate is more relevant today than it has been before, especially in the context of global warming (Beniston 2010). Schulte (2014) and Somero (2010) published articles on environmental stress and climate change respectively. Reading the two articles offers an understanding of how the two variables are interrelated and the effect that they have on living organisms. The manner in which the arguments are constructed presents with various positives and negatives. This critique will highlight the positives and negatives with the help of literature from other scholars. Schulte ( ...

Introduction

Climate change is a major environmental problem, causing concern to various corners of our ecosystem. It is a result of global warming, environmental pollution and inefficient use of our natural resources. Climate change has affected almost all living organisms, including plants, animals, microorganisms and undoubtedly, man. It poses a serious threat to our ecosystem and is listed as a major concern in the Grand Challenges of the U.N. for Millennium Development and Millennium Ecosystem Assessment (Garrett 490). A wide variety of its implications, have made climate change, an important topic for researchers. There has been more awareness among researchers ...

Tropical Rain Forests

They are located near wet tropical lowlands and uplands nearby the equator. A good example is the Amazon River rainforest found in Peru. The structure of the tropical rain forest can be described as full of ferns and shrubs and other plants that require less light. Tall trees forming canopies are common and hence the floor of the forest is dark and damp. It has many layers of decomposing animals and leaves. The biotic components include bamboo and rubber trees, lemurs, poison dart frogs, and anteaters. On the other hand, abiotic components comprise of water, light, rocks, and soil.

Introduction

An ecosystem is defined as the interaction of the organism and other nonliving factors in a certain community. The living components of an ecosystem, such as plants, animals, and other organisms, can be classified as the biotic component of the ecosystem, whereas the environmental conditions such as water amount, humidity, soil nourishment, temperature, and the like are termed as the abiotic factors. In an ecosystem, both the existing biotic and abiotic factors determine what kind of species live there. For example, turtles, which require a large amount of water to live in cannot possibly hope to survive in arid ...

Introduction Wheat (Triticum sp.), an extensively adapted crop, is one of the primitive and primary staple food crops in the world. Wheat is cultivated from temperate; dry to irrigated or rain-fed areas, to warm, humid or cold conditions. Such a high adaptability is attributed to its intricate genome (Acevedo et al., 2002). Wheat cultivation covers more land area compared to other commercial crops and endures to be an essential food grain for humans (Curtis, 2002). Estimations reveal that by 2050, the population of the world will reach 9.1 billion (34 percent greater than today); correspondingly, the food requirement and ...

1. DNA in forensic science: DNA contains the genetic code of a person. The genetic information stored in the DNA, is coded in the form of nucleotide sequence. The nucleotide sequence is formed by four fundamental nucleotides: A, T, G, C nucleotide, that formed a polymer in a set order. A typical human DNA, has 3 billion nucleotide bases. The DNA sequence is 99.8% identical in all human beings and is only 0.2% dissimilar. This dissimilarity is the basis for identification of the suspects in forensic medicine. No two human beings can have a DNA that is 100% identical. ...

In this paper, I am going to discuss an oratorical child leader whose name is Severn Cullis-Suzuki (BC BookWorld, n.d.; Cullis-Suzuki, 1994; speedybo's island, 1992). In 1992, she delivered her speech in the United Nations Earth Summit’s Plenary Session, Rio de Janeiro, Brazil. The theme of her oration is a call to end environmental abuse, wastage, and destruction. The focus of her speech is for conference delegates (e.g., governments, private corporate leaders, businesspersons, politicians, legislators, reporters, et al.) to assign a priority for children – during Suzuki’s and all other children’s time until future generations. In this ...
