what is the community made up of?
A community is formed by populations of different species living together and interacting with each other. Within a community: exists populations, which are a group of organisms of the same species who live in the same area at the same time. Within them, we can find the species which are groups of organisms that can interbreed to produce fertile offsprings. In order for both of these elements to make up a community, is for them to have relationships and interactions with each other. Some interactions between these species might be: competition, predation, symbiosis (mutualism), commensalism and parasitism.
Competition: interactions between
organisms, populations, or species, in which birth, growth and death depend on
gaining a share of a limited environmental resource. Predation:
the preying of one animal on others. Symbiosis: interaction between two different organisms
living in close physical association, typically to the advantage of
both. Mutualism: symbiosis that is beneficial to both organisms
involved. Commensalism: an association between two organisms in which one
benefits and the other derives neither benefit nor harm. Parasitism: habitually
relying on or exploiting others.
how do species interact with one another and their ENVIRONMENT?
As explained in the previous Essential Question, Communities are made up of the interactions between species. Species interact with one another and their environment through competition, predation, symbiosis, mutualism, commensalism, and parasitism. Competition is the interactions between organisms, populations, or species, in which birth, growth and death depend on gaining a share of a limited environmental resource. Predation is the preying of one animal on others, symbiosis is the interaction between two different organisms living in close physical association, typically to the advantage of both. Symbiosis that is beneficial to both organisms involved would be denominated as mutualism. Commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm, and lastly parasitism describes the relationship in which one species is habitually relying on or exploiting others. Ecosystems are then formed by the interactions of populations with the abiotic environment. Both autotrophs and heterotrophs obtain inorganic nutrients form their abiotic surroundings.
how can we build a sustainable ecosystem?
An ecosystem is a community formed by the interactions with an abiotic environment. Ecosystems have he ability to be sustained for a long period of time. Although human resources are unsustainable, natural resources teach us to live in a sustainable way, the three requirements for sustainability n an ecosystem are: energy availability, detoxification of waste products, and nutrient availability. Nutrients have the ability to be recycled, leaving no room for lack of chemical elements in the environment. Due to the fact that energy can't be recycled, the sustainability of these element depends on continuous energy supply. With the completion of these three elements in an ecosystem, the life within the environment has the ability of lasting for a long period of time.
Random samples are taken in studies involving large geographical areas or if limited time is available. Is random sampling a useful tool for scientists despite the potential for sampling bias?
Scientists are faced with the impossible task of immense areas that occupy tons of different species within the ecosystems. In order to estimate the number of organisms, random samples are taken in studies involving large geographical areas. Although the idea of random sampling doesn't offer a specific and detailed number of organisms, a general or percentage based statement of the amount of organisms living in an area despite the "bias sampling" is sufficient in order to have a specific enough record for scientists to study and go back at in a few years.
