theoretical framework challenged deficit perspectives. The author demonstrated that a range of inter-related factors may impact on an individual across different systems at any given time (e.g.‚ microsystem‚ mesosystem‚ exosystem and macrosystem). Ecological systems theory emphasises the interaction between more proximal individual factors (e.g.‚ biology‚ personality)‚ immediate environment (e.g.‚ family‚ school‚ peer group)‚ wider environment (e.g.‚ children’s services‚ socio-political factors‚ industry)

What is biological evolution by natural selection‚ and how can it account for the current diversity of organisms on the earth? 12. How can geologic processes‚ climate change and catastrophes affect biological evolution? 13. What is an ecological niche‚ and how does it help a population adapt to changing the environmental conditions? 14. How do extinction of species and formation of new species affect biodiversity? 15. What is the future of evolution‚ and what role should humans play

countries all over the world nowadays. The recent researches give us evidences that anxiety concerning nature pollution is increasing. The ecological security became primary for consumers. Thus‚ it is high time to reconsider the understanding the nature as our habitat as well as the source of raw materials and provisions which are necessary for our living. The ecological needs‚ based on necessity to keep safe the habitat and human health‚ are leading in nowadays society. Marketing directs business attention

If you are not sure of what the concept is or means search for the answer in your textbook and write it on a separate sheet of paper. If you know these terms you should do well on the test. Chapter 52 – Ecology and the Biosphere 1. Distinguish among the following types of ecology: organismal‚ population‚ community‚ ecosystem‚ and landscape. 2. Explain how dispersal may contribute to a species’ distribution.

In a chapter of Lauren Slater’s book‚ “In the Unlikely Event of a Water Landing”‚ she discusses a study done by Bibb Latane and John Darley that found that the is an inverse relationship between amount of witnesses and chance of someone intervening and also tested the Werther effect. She also uses the case of Kitty Genovese to illustrate this‚ how 40 people watched her slowly be murdered and no one intervened. This is similar to the situation at the Rocky Flats factory. Where many people knew what

quickly compared to regional dynamics and so due to the filling of ‘niche space’‚ communities would be ecologically saturated with species. This led to the conclusion that historical/biogeographic process like speciation and extinction rates could be dis-included when explaining local diversity. This resulted in local ecological processes being a default belief for terrestrial community ecologists. In contrast to this ‘Niche theory’‚ where diversity is limited to local factors‚ MacArthur &

different ways an organism interact with their physical environment in an ecosystem. As a habitat community a particular habitat is supposed to interact with one another and adapt. Some factors will influence a habitat will begin with ecological niche. Ecological niche describes how an organism responds to the allocation of resources and competitors e.g. by growing when resources are abundant‚ and when predators‚ parasites and pathogens are scarce and how it in turn alters those same factors i.e.

A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique place in that habitat: -its spot in the food web -its need for water‚ temperature‚ etc. -how it reproduces No two species share the same niche in the same habitat Community Interactions How do organisms interact? * Competition: 2 or more species wanting to use the same habitat and
