A community refers to the total number of populations that inhabit a specific location or area. This is part of the levels of organization of life. Arranged from the least complex to most complex it falls 8th in the category. Below are the organization of life:

a. Organelles - the basic part of a living organism. It refers to the different structures of the cell, whether prokaryotic or eukaryotic. (Ex. Mitochondria, nucleus)
b. Cells - building blocks of life that are composed of different molecules responsible for the function of an organism. (Example: prokaryotic, eukaryotic cells)
c. Tissues - combinations of cells that carry out a specific function in an organism. (Example: Human skin)
d. Organs - collections of tissues that perform specific functions. (Ex. heart, lungs)
e. Organ Systems - composed of interconnected organs that function as a whole. Many organisms, particularly mamamals, are composed of organ systems. (Ex. respiratory, circulatory systems)
f. Organisms – individual entities that specifically make-up a population. (Ex. Each tree in the forest is an organism, each animal in sea is an organism)
g. Population – species living within a specific location. It could be the same or different species that inhabit a place. (Ex. Birds are species in the forest as well as bears)
h. Community – refers to the total number of populations that inhabit a specific location. (Ex. All of the trees, insects, birds that inhabit the forest are a community)
i. Ecosystem – consists of all living things that function together as a group which also includes the non-living parts of the environment. (Ex. Rain water, nitrogen in the soil)
j. Biosphere – the highest organization of life that consist of all the collection of ecosystems in the planet. It includes the land, air, water, even the atmosphere of the planet.

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next
