different ecological relationship among organisms and their environment

Mar 9, Ecological relationships describe the interactions between and among organisms within their environment. These interactions may have. The interaction among organisms within or between overlapping niches can be Holt Environmental Science: How Species Interact With Each Other. Ecological scientists study organism-environment interactions across Some of the broadest patterns of environmental difference arise from the way our planet.

The sun is the main source of energy for biological systems on the surface of the earth. There are defining structures of cells for both plants and animals. There are structural and functional similarities and differences that characterize diverse living things. There is a relationship between structure and function at all biological levels of organization. Thousands of layers of sedimentary rock confirm the long history of the changing surface of the earth and the changing life forms whose remains are found in successive layers.

Transportation is the process of safely and efficiently moving people and products. Two of the fundamental forces that exist in the universe are gravity and electromagnetism.

Unbalanced forces acting on an object cause changes in its velocity. Understanding technological systems help us plan and control technological developments. While science is the study of the natural world, technology is the study of the human designed world.

Describe how science and technology work together. Describe how technology impacts society. Describe the flow of energy from the sun, throughout the earth system, living and non-living, from the cellular scale to the global scale, and describe the transformations of that energy as it moves through the system.

Describe the relationships among the parts of a system, the ways that they work together, the flow of matter or energy through the system, and the feedback and control mechanism present in the system. Design and develop the ability to create and send messages using technological devices.

Design and develop the ability to safely and effectively use tools and materials to build structures. Design and develop the ability to safely and effectively use tools and materials to convert energy into power. Design and develop the ability to safely and effectively use tools and materials to create bio-related products and systems using technology.

Objectives In this lesson, students compare various types of relationships among organisms i. Organisms that eat other organisms for energy. A group of similar organisms that can breed with one another. A group of individuals of the same species that live in the same area. All of the populations that live together in a certain area.

Ecological interactions

All of the organisms that live in a certain area and their nonliving environment. Describes a relationship in which two species live closely together.

An interaction in which one organism kills and feeds on another organism. Symbiotic relationship in which one organism lives in or on another organism the host and harms the host. Symbiotic relationship in which both species benefit from the relationship.

Symbiotic relationship in which one organism benefits and the other is not helped or harmed. Symbiotic relationship in which one organism harms the growth of another organism, while the organism itself is not affected. An animal that kills and eats other organisms. 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. 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.

Biological 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. Hunting seasons, catch limits, size restrictions, and quotas used for fish, seafood, and game are all ways in which governments of the world promote healthy and sustainable population sizes for these organisms.

Learn how populations grow and are limited in this resource from Mr. Niche represents the sum total of all the ways it utilizes resources in its environment: If two species share the same or a similar niche, they will both compete for the same resources and the worst competitor will be driven to extinction in that area.

This is called competitive exclusion. Habitats that are more complex in food sources, prey refuges, soil substrates, etc. Energy Flow The beginning teacher describes and analyzes energy flow through various types of ecosystems. Ecosystems include autotrophs organisms, such as plants, that manufacture their own food from external sources of energy and heterotrophs consumers, such as animals, fungi and many protists.

Once energy enters an ecosystem, it is passed from one organism to another by ingestion as food or decomposition. Primary producers convert light energy or, rarely energy from chemosynthesis, into chemical bonds. Consumers rely on producers for their energy sources.
