THE ECOSYSTEM: INTERRELATIONSHIPS BETWEEN
index-art.info A community is the term used to describe two or more populations of The biosphere includes all living beings and their relationships. Thus, in the first image, species would fall between population and community in a sense. community - all populations of organisms living in an area Feeding Relationships consist of rectangles resting atop each other; is basically a bar graph with the bars on their biogeochemical cycles describe the recycling of nutrients in an ecosystem commensalism - one species is helped, other not harmed/helped. POPULATIONS, COMMUNITIES, AND ECOSYSTEMS Chapter 2. of the populations of different species of animals and plants that live and interact Parasitism is a relationship between two types of organisms in which.
I am an organism. The mosquito that flies by your window is an organism.
Outline: The Biosphere, Ecosystems, and Communities
An organism is a single, living thing and can be an animal, a plant, or a fungus. Organisms grow and respond to their environment. A population is the term we use to describe multiple individuals or organisms of a single species that live within a particular geographic area. For example, there may be one population of painted turtles in one state and another population of painted turtles miles away in another state. 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. If the prey is not successful, it becomes a meal and energy source for the predator. If the prey is successful and eludes its predator, the predator must expend precious energy to continue the hunt elsewhere.
Predators can also be prey, depending on what part of the food chain you are looking at.
What is the relationships between organisms, species, population ecosystem, etc?
For example, a trout acts as a predator when it eats insects, but it is prey when it is eaten by a bear. It all depends on the specific details of the interaction.
Ecologists use other specific names that describe what type of food a consumer eats: Omnivores eat both animals and plants. Once again, knowing the Latin root helps a lot: For example, an insectivore is a carnivore that eats insects, and a frugivore is an herbivore that eats fruit.
This may seem like a lot of terminology, but it helps scientists communicate and immediately understand a lot about a particular type of organism by using the precise terms.

Not all organisms need to eat others for food and energy. Some organisms have the amazing ability to make produce their own energy-rich food molecules from sunlight and simple chemicals. Organisms that make their own food by using sunlight or chemical energy to convert simple inorganic molecules into complex, energy-rich organic molecules like glucose are called producers or autotrophs. Some producers are chemosynthesizers using chemicals to make food rather than photosynthesizers; instead of using sunlight as the source of energy to make energy-rich molecules, these bacteria and their relatives use simple chemicals as their source of energy.
Chemosynthesizers live in places with no sunlight, such as along oceanic vents at great depths on the ocean floor. No matter how long you or a giraffe stands out in the sun, you will never be able to make food by just soaking up the sunshine; you will never be able to photosynthesize.
Producers use the food that they make and the chemical energy it contains to meet their own needs for building-block molecules and energy so that they can do things such as grow, move, and reproduce. All other life depends on the energy-rich food molecules made by producers — either directly by eating producers, or indirectly by eating organisms that have eaten producers.
Not surprisingly, ecologists also have terms that describe where in the food chain a particular consumer operates. A primary consumer eats producers e. And it can go even further: A single individual animal can act as a different type of consumer depending on what it is eating.
During photosynthesis, plants capture light energy with their chlorophyll and use it to convert carbon dioxide and moisture absorbed from air into sugar chemical energy. Oxygen is released as a by-product Every major ecosystem has its particular green plants that carry on photosynthesis and release chemical energy carbohydrates, protein etc. Species that feed directly on producers plant-eating species. They are also called Herbivores. Species that feed on primary consumers.
Secondary and higher order consumers are called Carnivores.
Tertiary and higher level Consumers: Species that obtain their nourishment by eating other meat-eating species. Species that obtain their nourishment from eating both plants and animal species.
Also called Omnivores 3. They are the final link in the food chain.
