Biology Field Study Essay

First of all we located the animals and the plants abundance surrounding the mangroves ecosystem, to determine the population within each site. The materials were then gathered to commence the sampling for the abiotic factors. The measurements of the distribution of all organisms were measured first including the abiotic factors. A 14 metre long transect was made along

In south Texas there are several types of ecosystems one of those ecosystems are the dunes. South Texas dunes are found along the Texas coastline and the general abiotic conditions are sandy soil, high salt content, some fresh water, flooding in the occasion of severe storms and moisture from rain and waves. Sea Oats and Bitter Pancum are two types of plants that dominate the South Texas dunes. Bitter Pancum adaptation for living in this type of ecosystem is that they are tolerant to high salinity. Sea Oats are less tolerant to high salt but their adaptation is to grow rapidly. Some common animal species that live in the dunes are crabs, which are tolerant to high salt water, gulls, and terns feed on crabs and other species around the

The soil and biotic/abiotic features of the park vary greatly depending on the area of park being studied. The volcanic rock that underlies the

Zonation is the distribution of animals and plants into specific zones according to abiotic factors and characterised by its dominant species [15]. Mangrove zonation is the distinguishable categorisation of a mangrove ecosystem that extends from shore to inland regions. Definitive spatial variation of mangrove species has been recognised amongst different ecosystems worldwide and is accredited as being influenced by abiotic and environmental factors [16]. In Eastern Australia, the majority of mangrove forests may be divided into landward, middle and seaward zones, based off of their placement in relation to tidal position. The following points represent the typical physiognomies characterised by mangroves in their corresponding zones:

A chemical reaction involving the transfer of electrons rather than molecules is classified as a Redox reaction. A reaction involving the loss of electrons is called Oxidation, and a reaction involving the gain of electrons is called Reduction. Oxidation and Reduction always occur together, as one reactant loses electrons, and the other gains them. This exchange often effects the physical states of molecules, as their solubility is changed with their charge.

The cephalopodor octopus is a marine organism that inhabits many diverse regions of the ocean. Its food source consists of crabs, small fish, clams, mussels and other marine animals. The octopus is a predatory animal and has developed many skills to aid in its survival in the environment it has adapted to.

(d.) Biologists agree that there is sufficient evidence to concede to the sexual selection hypothesis and that the food competition hypothesis needs further testing.

The purpose of the “chi-square test” was to see if our data was in an acceptable range of a specific ratio listed above. The chi-square test took into account the expected deviations in the F2 offspring’s alleles.
