| Receiving Energy | Plants and animals cannot make their own food so they recieve their energy by eating other organisms |
| Comsumer | A living thing that eats other living things. |
| Herbivor | An animal that eats only plants |
| Carnivor | An animal that eats onlyother animals |
| Omnivoe | An animal that eats both plants and other animals |
| Decomposer | A living thing that feeds on dead materials,breaking them down and returning them to the enviroment. |
| Food Chain | The arangement of other living things in an order in which each uses the mext as a source of food. |
| Food Web | A combination of all the food chains in an ecosystem. |
| Food Pyramid | A diagram to show the amount energy avaliable changes at each step of the food chain. |
| Focus | All living organisms in an ecosystem needs energy to carry out theirlife functions. |
| Using energy | This step involvs green plants such as trees,grasses and some kinds of small living things such as algae |
| Producers | A living thing containing chlorophyll and capable of using sunlight to make it's own food from materials taken from the sun.and |
| Limiting Factor | A factor controlls the number of living thingsthat an ecosystem can support. |
| Carrying Capacity | The maximum number of living things that a given ecosystem can support without danger to the survival of the living things. |
| Cycle | The movement of resources in an ecosystem that results in materials being uused again and again. |
| Energy Flow | Living things get the energy from the food that they eat.in an ecosystemthe energy flows from one living thing to anotherin these steps.What a living thing eats and where it gets it's food.Each living thingfills a niche in this energy flow. |
| Energy from the Sun | The sun and the physical environment provide living things with the materials that they need such as energy from sunlight,also nutrients from the water,soil and air. |
| Amount of food | The populatinons with the largest amount of food energyavaliable to them are the biggest.And the populations witht the least amount of food energy avaliable atre the smallest. |
| Number of Oranisms | Make their oun food by using energy from sunlight,air,waterand chemicals. |
| Balance in Ecosystems | Look around your classroom ,the numberof stundents that can be taught in the classroom is limited by factors. |
| Water Cycle | Water can be reused in a certinn kind of cycle |
