1. Fill in the ecological hierarchy chart below. Different levels of ecological study (1149)
Ecological Level | Description | Example | Organismal | Organismal ecology includes the subdisciplines of psychological, evolutionary, and behavioral ecology, is concerned with how an organisms structure, physiology and (for animals) behavior meet the challenges posed by its environment. | How do hammerhead sharks select a mate? | Population | A population is a group of individuals of the same species lining in an area. Population ecology analyses factors that affect population size and how and why it changes through time. | What environmental factors affect the reproduction rate …show more content…
Winter temperature average around 0 degrees Celsius and in the summer the average is around 35 degrees Celsius. | Birds and insects | Tundra | Precipitation averages from 20 to 60 cm annually in arctic tundra and up to or more than 100 cm annually in alpine tundra. Winters are long and cold and averages somewhere around -30 degrees Celsius summers are short with low temperatures normally less than 10 degrees Celsius. | Large grazing musk oxen, caribou and reindeer are migratory. Predators include bears wolves and foxes. Many birds migrate here for the summer. | 8. What feature of a tropical forest accounts for the great biodiversity? The great biodiversity in the tropical rainforest is most probably contributed to the fact that it has a good amount of rainfall and it also has dry seasons. This results in the optimal climate for many different species to thrive and successfully reproduce. 9. In the cross section of a marine ecosystem below, label the following zones: Neritic, Oceanic, Benthic, Photic, Pelagic, Aphotic, Abyssal, Intertidal. …show more content…
This relates to the principal of competitive exclusion because two species can not survive together in a permanent community if the have the same niches. There are many negative results that could occur if the interspecific competition is intense enough. The first and most drastic of the results would be complete extinction of one of the species because of lack of resources or lack of organization needed to get complete and full use of the resources that they are able to gather. Another result that could occur would be that the species that is becoming extinct from the battle for resources in that area would decide to move on but would then face the challenges of finding an area with shelter, nutrients, energy, and proper nesting areas. This scenario could also result in the extinction of the species if they fail to find proper shelter and
