(1) Explain the differences between the levels of ecology and provide one example of each type: individual, population, interactions, community, ecosystem, and biosphere.

A.Individual – a single organism, this level can include any living organism from a plant to an animal. Exp. mouse
population – a group of individuals of the same species living in a given area at a given time. Exp. Sheeps, cows, humans
interactions –
community – a group of interacting plants and animals inhabiting a given area. Exp. Woods – deer, trees, bears, bushes
ecosystem – the biotic community and its abiotic environment, functioning as a system. Exp rain forest – rain, sunny, trees, flowers, birds, monkeys, snakes
biosphere – a thin layer about earth in which all living organism exist. Exp. all ecosystems on land and water.

B.Individual: a single organism and example would be a crow.
Population: organisms of the same species interacting in there given area, and example of this is the murder of crows.
Interactions: one organism affecting another organism or population, an example of this would be the crows over eating the worms and the worm populace decreasing.
Community: all populations of different species living and interacting within an ecosystem. This would be the worms being eaten by the crow and having the crow eaten by the hawks, or the completion of the crows by ravens, all within the same field.
Ecosystem: Organisms interacting with other organisms. This would take into effect the amount of precipitation effect on the grass in the field affecting the worms which affect the crows.
Biosphere: thin layer about the earth that supports all life. This links ecosystems with earth systems, such as exchange of minerals. An example of this is the role the plains the crow live on effecting the carbon cycle.
The levels of ecology basically go from a single organism to multiple organism then how those multiple organism interact with other populations and finally how those communities work with the earth.

C.Individual – a single organism, this level can include any living organism from a plant to an animal (ex. A dog, a bird)
Population – a group of individuals of the same species living in a given area at a given time. (*some populations compete with other population for limited resources such as food, water, or space)
Community- all populations of different species living and interacting within an ecosystem (*individuals of these populations interact among themselves and with individual of other species to form a community)
Ecosystem- organisms interact with the environment in the context of ecosystem. Ecosystem functions as a collection of related parts that function as a unit. (*ecosystem consist of two basic interacting components living biotic and nonliving abiotic.)
Landscape-an area of land (of water composed of patchwork of communites and ecosystem (*although each ecosystem on the landscape is distinct in that it is composed of a unique combination of physical conditions (such as a topography and soils) and associated sets of plant and animals population.
Biomes- the broad-scale regions dominated by similar types of ecosystems such as topical rain forest, grasslands and deserts
Biosphere- the highest level of organization of ecological system is the biosphere-the thin layer about the Earth that supports of all life. (*in context the biosphere, all ecosystem both on land and in the water are linked through their interactions-exchanges of materials and energy with the other component of Earth system: atmosphere, hydrosphere, and geosphere.)

D.Individual: one organism and focuses on what characteristics allow the species to survive
Population: a group of organisms; the amount of individuals in the pop. And how #s change
Interactions: interactions among individuals and interactions among a community
community: more than one group of species interacting with each other
Ecosystem: organisms interact with the environment; biotic + abiotic factors
Biosphere: all ecosystems are linked through their interactions with-exchanges of materials and energy other components of the earth system
