species feeds on another organism by living on or in the host. Mutualism occurs when two species interact in a way that benefits both. Commensalism is a species interaction that benefits one species but has little‚ if any‚ effect on the other. Ecological succession is the gradual change in species composition in an area. Early successional plant species grow close to the ground‚ establish large populations‚ and have short lives. Late succesional plant species are mainly trees that can tolerate

sparsely-populated areas to be overpopulated‚ as the area in question may have a very meager or non-existent capability to sustain human life (e.g. the middle of the Sahara desert or Antarctica). The resources to be considered when evaluating whether an ecological niche is overpopulated include clean water‚ clean air‚ food‚ shelter‚ warmth‚ and other resources necessary to sustain life. If the quality of human life is addressed as well‚ there are then additional resources to be considered‚ such as medical care

from local sources across the world. The volume of water commandeered by the industry is to the tune of 8.9 billion litres annually. The rapid rate at which water is drained causes massive amounts of disruption to local ecosystems. The extent of ecological damage means that it takes decades for an ecosystem affected by the industry to heal. This water is then packaged in bottles made of various plastics. Since plastics do not biodegrade easily‚ these bottles‚ unless disposed of properly‚ find their

Adaptive Radiation Adaptive radiation occurs most often in new environment with a variety of different unfilled niches so that plants and animals that are not adapted to those areas can exploit the resources in the respective niches. Once individuals begin exploiting the new niches‚ mutations that will benefit the species will spread throughout the population via natural selection giving the owners an overwhelming advantage over others without the mutation and throughout evolutionary time

Extinction Extinction is the termination of evolutionary lineage. The most common extinction event is the loss of a species. There are many reasons why a species might die out. Human intervention (either directly or indirectly) has become the leading cause of species extinction (possibly for the last fifteen thousand years). Species and Populations An important distinction must be made between true extinction and extirpation. Extirpation is the loss of a population‚ or loss of a species

boredom of their routine. Also habituation can be reverse by developing a traveling mindset because it helps discovering how things really look and work. De Botton does not go into how this can affect science but it can be related to the author Lauren Slater’s essay “Who Holds the Clicker?”. On her essay Slater explores the subject of mind control though stimulation of the brain by presenting examples of surgical procedures and how they were conducted. She explains some cases
