ways in which distinctive ecologies can develop along routeways (10 marks) Routeways such as roads‚ railways and canals can provide habitats for many species of plant and insect life because they often act as protected areas in which ecological succession can occur. There are several ways in which this can happen. One way in which ecologies can develop along routeways is that plant seeds‚ e.g. Oxford ragwort or buddleia‚ that have become windborne can be transported along by cars or trains and are

Winthrop University’s Successional Plot’s Soil P.H. Meredith Hamilton Biology- Westover September 30‚ 2011 Abstract The question of this study pertained to the amount of vegetation that was occurring on each of the succession plot’s ground floor. There are three successional plots in Winthrop University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to

Environment: All the organisms (biotic) and the conditions (abiotic) which exist in an area Abiotic factors: all the non-living factors in an environment‚ such as rainfall‚ temperature‚ soil. Biotic factors: All the living organisms in an area – such as producers‚ predators and parasites. Population: All the members of one species living in an area Community: The total of all the populations living in

cycle. 2. Ecological succession is the transition in the species composition of a community following a disturbance in the ecosystem. This process can occur either as primary or secondary succession. In primary succession‚ the process begins in a virtually lifeless area where soil has not yet formed‚ such as on a newly formed volcanic island or on the rubble of a retreating glacier. Most of the time‚ the only life-forms present in the early stages of primary succession consist of autotrophic

represents the niche of species A. Species A is biologically constrained from the striped area of its niche by species B. This is an example of A) dynamic stability. B) facilitation. C) commensalism. D) competitive exclusion. E) secondary succession. Answer: D Topic: Concept 53.1 Skill: Application 6) The sum total of an organism’s interaction with the biotic and abiotic resources of its environment is called its A) habitat. B) logistic growth. C) biotic potential. D) microclimax.

The structure or spatial distribution of a community or ecosystem can be described by: a. Physical Appearance : relative sizes‚ stratification‚ and distribution of its population and species b. Species Diversity or Richness : the number of different species c. Species Abundance : the number of individuals of each species d. Niche Structure : the

on the succession development‚ whereas others have a dramatic influence over a long period of time‚ such as human activity. These factors‚ over time‚ result in the progression of a succession until the climatic climax vegetation is reached. However‚ sometimes these factors can mean that a plagioclimax is reached‚ as they prevent the succession from progressing any further and the climatic climax vegetation is never achieved‚ which in the UK are Oak‚ Hawthorne and Birch trees. This succession results

Ecological Succession Ecosystems are constantly changing in response to natural and human disturbances. Changes that occur in a community over time is called ecological succession. Succession can be a slow and gradual response to physical changes such as a change in rainfall or temperature. Succession can also be abrupt due to such things as fires or volcanoes. There are two kinds of succession: 1. Primary succession 2. Secondary succession Primary succession occurs on surfaces
