Ecological Organization ( Read ) | Biology | CK Foundation
Living things are organized in their habitats, and make up a structure of organisation. These include individuals, populations, community, ecosystems, biomes and A biosphere is the sum of all the ecosystems established on planet Earth. Copyright © eSchooltoday in association with az-links.info Community- multiple populations of different species living in the same area. This includes the bison, hawk, and snake. Ecosystem- while a community consists. Ecology is the study of the relationship between organisms and their starting with the biosphere, ecosystems, communities, populations, organism, cell, atom, .
The biosphere is made of different ecosystems. Ecosystems are made of different communities. A community includes all the populations in an area. Population in made of the same species that live in the same area and make up a breeding group. So populations are made of organisms.

Organisms are made of cells, cells are made of atoms, and all atoms are made of matter. An ecosystem is an ecological unit that includes at the interacting parts of an environment in an area. Ecosystems consist of abiotic and biotic factors. Abiotic factors are the nonliving components of an ecosystem. Abiotic factors can be divided into man-made and natural factors.
Examples of man-made abiotic factors include automobiles, buildings, planes, boats, bridges, roads, cities and towns. Examples of natural abiotic factors include sunlight, precipitation rain or snowtemperature, slope and drainage of the land erosionchemistry of soils and atmosphere, volcanic activity, earthquakes, and storms hurricanes, tornados, sand storms.
Biotic factors are the living components of the ecosystem.
- What is the difference between organism, population, community, ecosystem, biome and biosphere?
- What is the relationship between the biosphere, a biome, and an ecosystem?
Examples of biotic factors include plants, animals, protists, humans, bacteria, and all other living organisms. Biotic factors may interact with each other in 3 ways. Competition for food, living space, or mates. The relationship between predators and prey.
And finally in symbiosis. Abiotic and biotic factors can interact. For example climate and soil conditions determine which plants will live in a certain area. The availability of land for predators to hunt and live is affected by the increasing number of housing being built for humans.
Biotic relationships are all the relationships among organisms living in a given area.
There are 3 types of biotic relationships: Organisms interact through competition. Competition is the use or defense of a resource by one individual that reduces the availability of that resource to other individuals. In other words, competition is the use or defense of food source, living space, or mates so that others cannot have it.
There are two main types of competition: Intraspecific competition is the competition between organisms of the same species.
Usually competing over mating rights.Ecology - Rules for Living on Earth: Crash Course Biology #40
The male that wins the fight gets to mate and the loser has to fight a different male or wait another year to mate. This insures that the healthiest individual best adapted to their environment will pass on their genes to offspring at a greater rate than individual less fit.
Intraspecific competition is one of the driving forces of evolution. Evolution is the change in a species over time. This change occurs by mutations that may occur that can cause a species to become better adapted to their environment. Interspecific competition is competition between organisms of different species. Interspecific competition is often less intense than intraspecific competition because individuals of different species do not compete for exactly the same kinds of food, space, or mates.
Outline: The Biosphere, Ecosystems, and Communities
An example of interspecific competition is the competition between predators for the same kind of prey.
The competitive exclusion principle states that two competitors cannot coexist on the same limiting resource. Meaning that if the availability of a resource such as food decreases, two competitors cannot compete for that same resource. Both competitors will be negatively affected by the decrease resource. A community is the term used to describe two or more populations of different species that occupy the same space at the same time. For example you could talk about the community of Yellowstone National Park that is made up of numerous animals such as elk, bighorn sheep, coyotes, porcupines, different species of frogs, and fish and insects and so forth.
An ecosystem is the term used to describe both the biotic living and abiotic nonliving factors in a system. The ecosystem in the image below is made up of birds, frogs, fungi, plants, mammals, bacteria, the water, the run, the rocks, the soil, and so forth. A biome is the term used to describe organisms that occupy a certain area.
Levels of Organization in an Ecosystem
Biomes are determined by the primary vegetation type, the climate of the area, and the geographic location. The plants and animals in a biome share common traits that are specific to the individual biome those plants and animals inhabit.
A biosphere is the term used to describe the combination of every ecosystem on the planet.
Our biosphere is Earth. The biosphere includes all living beings and their relationships. If you wanted to include species in this list, it becomes slightly trickier. There are many definitions of species but a common one is that a species includes every member of the species within multiple populations.
