Building ecological concepts

• Something that you can´t explain in your own words is unknown

• Here is a list of concepts that you will need for the next class in biology

Clearing our mind • Ecology• Ecosystem• Habitat• Niche • Community• Population• Abiotic • Biotic• Interaction• Relationship

Three steeps

First: write your ideas about each oneDon´t worry about making mistakes

Second: Look in the dictionary or use an internet source

Last stepWrite in your own words a new phrase (no copy paste) that gives a clear idea about each concept

ConceptEcology:

The scientific study of the distribution, abundance and dynamics of organisms, their interactions with other organisms and with their physical environment. Source: http://www.britishecologicalsociety.org

Ecosystem: All organisms and the abiotic environment found in a defined spatial area. For an ecosystem to be a useful unit of biological organisation, it is generally assumed to be the collective description of a community and its physical environment. – Source http://www.britishecologicalsociety.org/about-ecology/key-concepts-in-ecology/#sthash.hBXHynM2.dpuf

Habitat: Refers to the kind of place where an organism normally lives. It includes the arrangement of food, water, shelter and space that is suitable to meet an organism's needs. You can think of this as the "address" where an organism lives. Habitat is the place a plant or animal lives inSource http://www.nmnaturalhistory.org/BEG/EcoConcepts_IV_SBEC.html

ConceptNiche:

Is the "occupation" of an organism. It defines the role of an organism in an ecosystemIt includes the adaptations and strategies a species uses in it’s environment.The sum total of all the resources used by, and the biotic and abiotic conditions suffered by, a species. Each resource (e.g. food, shelter) and condition (e.g. temperature, exposure) forms an axis of a multi-dimensional ‘hypervolume’ that describes the ecological requirements and constraints that allow a species to maintain long-term average population growth. An important distinction exists between a species’ fundamental niche (where it could persist) and its realised niche (where it does persist). – See more at: http://www.britishecologicalsociety.org/about-ecology/key-concepts-in-ecology/#sthash.7afe8gLb.dpuf

Community:• All species in a defined spatial area or ecosystem, which interact via trophic, competitive, commensal, amensal

or mutualistic interactions. Members of a community may interact directly, or indirectly (e.g. apparent competition) if they share interaction links to other species in the community. There is some debate regarding the true scale at which a ‘community’ can be defined as an independent unit of organisation, with no interaction links outside its boundaries. A common obfuscation is to define a ‘sub-community’ (an arbitrarily chosen set of species that are part of a wider community) as a ‘community’ associated with a key species (e.g. the herbivore ‘community’ associated with a certain plant species). – See more at: http://www.britishecologicalsociety.org/about-ecology/key-concepts-in-ecology/#sthash.7afe8gLb.dpuf

ConceptPopulation

A population is all of the individuals of the same species within an ecological community. Ecologists are interested in the growth of a population, fluctuations in population size, the spread of the population, and any other interactions within the population or between it and other populations.http://education-portal.com/academy/lesson/population-ecology-definition-theory-model.html#lessonA population is a subset of individuals of one species that occupies a particular geographic area and, in sexually reproducing species, interbreeds.http://global.britannica.com/EBchecked/topic/470416/population-ecology

Abiotic factors- There are the nonliving parts of an organism’s environment. Examples include air currents, temperature, moisture, light, and soil. Abiotic factors affect an organism’s life

Interactioncompetition (biotic interaction)competition biotic interaction in ecology, utilization of the same resources by organisms of the same or of different species living together in a community, when the resources are not sufficient. http://global.britannica.com/search?query=interactions+in+ecology

Some types of interaction in ecologyCompetition, comensalism, predation, herbivorism, parasitism, mutualism,
