An ecosystem is consisted of of all the living animals and plants and also the non-living matter in a details place, favor a woodland or lake. Every the living things in an ecosystem count on all the various other things - living and also non-living for ongoing survival - because that food supplies and other needs.

You are watching: What do all organisms depend on

In part ways, the actions and reaction the take place within one ecosystem are favor a spider net - once one strand is broken, the net starts to unravel. What influence one component of one ecosystem, influence the whole in part way.

The idea of the internet of life is displayed by the interdependence within an ecosystem. Animals and also plants rely on a complex system of food because that survival. In a common prairie ecosystem, the could work prefer this: The sunlight provides energy for the grass; grasshoppers feed on the grass; birds and frogs eat the grasshoppers; snakes eat birds, frogs and also mice; owls and also hawks will certainly eat the birds as well as snakes, frogs and mice. When an pet dies, the is decomposed by worms, fungi and bacteria action and nutrients room released come the soil during the decaying process for the grass to use again. Connecting the numerous plants and also animals with lines representing your functions and also food chains within this would produce a tangled maze. It is obvious that all forms of life in the ecosystem are dependent top top all various other living and also non-living points for food, nutrients and also energy.

ObjectiveStudents will understand that an animal's needs identify its preferred habitat.Students will know the principle of ecosystems and also interdependence.Students will know that interrelating communities are materials of one ecosystem.Activities


Demonstrate the concept of interdependence to students by setting up a row of dominos v enough an are between one ar that will allow a chain reaction to protect against at that allude after the first has been pushed. And/or use play blocks collection up in a shape of a pyramid; ask student to eliminate several blocks. Every block removed causes a adjust in the structure--some reactions are an ext severe than others; for instance, if a bottom or facility block room pulled, the system collapses.


Go outside and mark turn off a big area. A field with varied vegetation is best. Division the area into sections making use of a measure up tape. Have actually students map the area by observing and identifying animals (insects, birds, signs) and noting their location. To compare the different animals by their locations.

Are over there differences?What space they?Why?


Group students right into teams. Go outside and also identify distinctly different vegetative areas, such together a lawn, woods, and open field, marsh, or a pond. Assign a team to every area or ecosystem. Using move nets, dip nets, magnifying lenses, egg cartons, trowels, pans and plastic bags, collection plant and insect specimens from each area. Minimize the influence by keeping pets live and also taking only parts of plants, such as a leaf. Document or draw pictures of tree or animals that room not collectible.

After collecting samples and also data, regroup for comparison of the areas. Room there differences? Similarities? What and why? identify your specimens as to what they do in your ecosystem.


Cut out or attract pictures the plants and animals that exemplify or display a food chain. Paste these on cardboard and assemble a food chain mobile(s). Include world as part of the food chain, if friend like. For example: sun, grass, grasshoppers--grass, birds, frogs, grasshoppers, snakes--birds, snakes, frogs, mice, and so on.


Make several indications representing plenty of of the materials of an ecosystem. Include animals, plants, soil, water and the sun. Several animals and also plants the are part of an interconnecting food chain have to be settled before hand. Students should pick a sign and wear it by using a string approximately the neck. Have them sit in a circle facing each other. Next, connect all the components (students) that are pertained to each other in one ascending bespeak by having actually them take host of the wire one in ~ a time, in order to weaving a, The internet of Life. The internet should be complicated by the time they room finished.

After anyone is "connected" questioning one crucial component come drop the string. This represents elimination native the system. Any other related contents should also drop the string.

What wake up to the system? discuss the ide of interrelationships within ecosystems. Exactly how do people assist keep, or not store the mechanism in balance?
