Niche that the organism fills The ecological niche or niche of an organism is the place and role in nature. This encompasses what it does, who it feeds, what it feed on as well as what it pollinates. Considering the role that the Brenton Blue butterfly fills, we find that like other butterflies, it serves as a pollinator. In this case, the Brenton Blue is a pollinator for its food plant, Indigo (scientific name Indigofera erecta). When the butterfly lands on the plant to feast on the nectar…

Threatens the survival of fish and other aquatic life forms. When the nutrients present in the aquatic ecosystems increase, there will cause the phytoplankton and the other photosynthetic plants grow quickly, known as algal blooms. As the result, the algal blooms will limit the oxygen required amount for the respiration by the other aquatic animal and plant species. Oxygen depletion happens when the plant life decrease, die and decompose. When the oxygen dissolved reach the maximum levels, the…

Mangroves are the typical coastal ecosystems stand out as a distinct forest type at the interface between terrestrial, estuarine, and near-shore marine ecosystems, where sea water and fresh water mixes and creates the favorable salinity condition for the mangrove species to grow. Mangroves have special adaptability to grow in such harsh environment; also, it provides massive ecosystem services to the coastal communities (Yusuke et al, 2012). However, mangrove species are increasingly threatened…

In the literature, different equations are used to calculate the energy requirement for birds (Emmans, 1974, Peguri and Coon, 1988, NRC, 1994, Sakomura et al., 1993, 2006), the factorial model has been the basis for the elaboration from these models, estimating the requirements consider the differences in weights, body composition, potential for growth and production of the animals, as well as the environment. The factorial method is based on the principle that the requirement in energy or…

Proposal Background Duckweed also know as Lemna by her genus is a small plant, that is mostly found in sub-polar and tropics regions in ditches, ponds, lakes and slow flow-flowing rivers. Duckweed have the main function of remove waste of water, however the main problem is that grows fast (Moss et al.2012). Research Question Is the use of different concentrations of phosphates will affect the duckweed? Hypothesis The more phosphate use the more the plant will be affected. Aim To…

Human Threats: For both of these species the common habitat is the Marram grass and fresh water regions within the Nature Reserve. As there are many contributing factors to the loss and damage of both of these habitats, it is difficult to pinpoint which factor causes the most destruction. Habitat loss and fragmentation, an overall decline in groundwater quality, water pollution incidents, water shortages and predation from feral populations such as ducks and competition from introduced exotics…

fly on Jacaranda trees compared to infestation levels on indigenous Bush Willow trees. By Cian MacFie Hyde Park High School Table of Contents Introduction Alien Invasive plant species are a large threat to ecosystems all over the world today and have many negative consequences for biodiversity (van Wilgen et al. 2011). Thousands of alien invasive plants have been introduced into South Africa with some becoming naturalized and some becoming invasive…

anacondas that have entered Florida's ecosystem are native and are many problems to the native species that are already inhabitants of the Everglades. What these pythons have done is they are distorting the natural food chain of that ecosystem this is drastically changing…

Introduction: The purpose of this experiment was to create a model of a self sustaining ecosystem for simulation. The eco column is a small model of the ecosystem and is a closed system. Most of the things that happen inside of the eco column will be similar, but there will always be outside factors which will not be taken into account. The goals of this experiment was to study the connections between the chambers and how they will affect the results. Each chamber in the eco column had a…
