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

The results of my ecological footprint quiz were that I was living an ecologically conscientious lifestyle‚ and I would need only 0.52 Earths. My highest consumption had been in the food footprint. I also noted that I had a really high travel distance annually‚ which was at approximately 5‚000km‚ due to a long travel to and from my university. I believe that the results reflect my lifestyle. I would say that I am pretty "eco-friendly." When I go grocery shopping‚ I bring my own bags instead of using

Media systems dependency theory (MSDT)‚ or simply "media dependency‚" was developed by Sandra Ball-Rokeach and Melvin DeFleur in 1976.[1] The theory is grounded in classical sociological literature positing that media and their audiences should be studied in the context of larger social systems. MSDT ties together the interrelations of broad social systems‚ mass media‚ and the individual into a comprehensive explanation of media effects. At its core‚ the basic dependency hypothesis states that the

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 niche is how a certain organism reacts to limited resources
