Vegetation

plant species are extremely aggressive (invasive) and can take over large areas of aquatic habitat. The floating mat of vegetation of macrophytes covers available sunlight from the water surface. The direct effect of this is low production in natural fish food (Phytoplankton – Zooplankton species) thus resulting in overall low fish productivity. The bloom of macrophyte vegetation result also in massive fish kills due to high oxygen demand and competition for available nutrients. These invasive…

world. It is twice the size of India, and over half the size of America. Also, it is home to around 2 and a half million different insect species as well as over 40000 plant species. The Amazon Rainforest has a mossy ground cover and is rich with vegetation, animals and insects It has many slopes, cliffs and hills for waterfalls…

Australia is in the South Pacific and the Indian Ocean. It is composed of the Australian continent, the island of Tasmania, and the overseas territories. Australia is in the southern hemisphere. Australia is located off the southeast coast of Asia, next to Russia, Canada, China, the United States, and Brazil. Its land is as large as about four-fifths of China. The coastline of 3,700 km has the Pacific Ocean to the East and the Indian Ocean to the West. It is also the only exclusive city state in…

The Paracas and Nazca cultures thrived in what is now Peru from around 600 - 175 BC and 1 - 700 AD, respectively. The depiction of ritual sacrifice plays a significant role in the art of both the Paracas and the Nazca cultures. We see examples of this ritual sacrifice in the intricately decorated Paracas textiles and beautifully painted Nazca ceramic pottery. One example of ritual sacrifice that we see in both the Paracas and Nazca cultures is that of trophy heads. A trophy head was…

and moisture content was tested. In the soil that was collected from the creek, there was 0.16% moisture in it and 84.26% organic content. In the soil collected from the footpath, there was 6.30% moisture and 93% organic content. - Vegetation: Some of the vegetation present in OSC includes:  Fleabane  Wandering Jew  Castor Oil Plant …

There are very many types of climates throughout the world. Climate varies depending on the location on the globe. The Tundra and the Humid Subtropics have two very different climates. The Tundra is generally very cold. While the Humid Subtropics are generally much warmer. The Tundra is very cold. Tundra climate is usually found between the 60-75 degree latitude lines. Tundra climate is mainly found along the coast of the Arctic Ocean. Tundra is a transition climate between Ice Cap and…

CHAPTER ONE 1. INTRODUCTION 1.1. BACKGROUND AND JUSTIFICATION Pan African Orogen (PAO) was formerly introduced by Kennedy (1964) to designate the peak of a wide spread orogenic thermo-tectonic episode characterized by intense period of reactivation and crustal formation. The term Pan African Orogen was used to describe the structural differentiation of Africa into cratons and mobile belts during the Neoproterozoic to earliest Paleozoic time (Kennedy, 1964). However, Kröner (1984) reformulate…

sensitive to the changes in salinity, hydrology, and productivity of their ecosystems. Everglade restoration is a big part of keeping the alligators safe. Alligators control long-term vegetation dynamics in the wetlands by reducing the population of mammals. These animals would overgraze the Everglades and kill the marsh vegetation. Since these Alligators are such a big part of the environment, it may help to reduce coastal wetland losses in Louisiana. They also help protect water birds while…

Darwin and Dinosaurs exhibit at MOSH Museum The visit to MOSH on Saturday was my first time going to the museum. I was surprised by the size of the building and how many exhibits and artifacts they were able to show inside. The Darwin and Dinosaurs exhibit was really cool. It was neat to see and read about Darwin and other scientists of the time while being by displays of massive dinosaurs. I learned many new things about Darwin 's life and the evolution of organisms at the exhibit, and had a…
