Succession‚ the process of a community changing over time‚ can be broken down into sub groups such as ecological‚ primary‚ pond‚ and secondary. Ecological succession being the most basic. In the Succession Lab‚ we observed a community in a ecosystem. As we recorded the data each class‚ we observed that succession takes place with rapid speed for in each observation‚ a new specimen is identified. A niche is how the organisms live‚ what their role in the community is. For example‚ an ecological

Ecological Succession Abstract: To be able to effectively determine and differentiate the various types of bacteria present during a two week fermentation process of both cabbage and cucumber using a variety of selective media. If fermentation is performed‚ then the CFU/ml of the bacteria should decrease along with the pH. Introduction: The fermentation of foods has been a long standing tradition and practice among many civilizations‚ as it was once a means to keep foods fresh and or edible over

Ecological Succession… 1 Ecological Succession is… • The observed process of change in the species structure of an ecological community over time. • The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. • Succession occurs in all natural environments. Each environment has a particular name that expresses the nature of their ecological succession: Primary and Secondary

FRQ: Ecology Question Ecological succession from a pioneer community to a climax community is an easy process to understand once you know each step. Ecological succession is the transition in the species composition of a biological community‚ often following ecological disturbance of the community. There are two types of ecological succession‚ primary and secondary. Primary succession is the establishment of a biological community in an area virtually barren of life‚ where there were originally

Ecosystems: Change and Challenge The Structure of Ecosystems Ecosystem: a dynamic‚ stable system characterised by the interaction of plants and animals with each other and with the non-living components of the environment The components of an ecosystem are categorised as either biotic and abiotic Biotic means the living environment‚ components include: i). Vegetation (living and decomposing) ii). Mammals‚ insects‚ birds and microorganisms Biomass-the mass of material in the bodies

Succession Lab INTRODUCTION: The purpose of our lab was to begin to understand the rates of succession. Succession is a number of persons or things following one another in order or sequence. Considering that all living things follow some sort of order‚ Joey Collins‚ Brian Carman‚ Chris Broadwater‚ Marisa Grondin‚ and I attempted to figure the succession rates of two different forests. In order to do this we used the forest behind the elementary school and the forest behind the track‚ by the

Chart 3.1: Velocity at 3 degrees Chart 3.2: Velocity at 6.3 degrees Chart 3.3: Velocity at 8.5 degrees Chart 3.4: Velocity at 90 degrees Discussion: The results that were observed from this lab helped prove what was hypothesized. As chart 1.4‚ 2.4 and 3.4 displayed the object dropped off of the 90 degree slope was the quickest to cross 200cm‚ had the highest velocity and the highest acceleration. This was because at 90 degrees the gravitational

Lab: Sampling Bacteria Purpose: Refer to handout sheet. Materials: Refer to handout sheet. Procedure: Refer to handout sheet. Pre-Lab Questions: 1. Why is one dish being reserved for the class as a "control"? Having a controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar

Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly
