| A system | made of many parts that work together for a purpose |
| The input of the bicycle system | the rider |
| The output of a bicycle system | dust from spinning tires |
| The parts of a bicycle system | handlebars, pedals, gears, frame |
| ecosystem | all the living and nonliving things in an environment |
| Example of a large ecosystem | the desert |
| Example of a small ecosystem | the rotting cactus |
| The living parts of an ecosystem | animals, plants, fungi, protists, bacteria |
| The nonliving parts of ecosystem | air, water, soil, sunlight, climate, landforms |
| What do plants and animals in desert do? | They conserve water and stay cool |
| How do saquaros adapt to desert | stems expand and fill with water |
| Grasslands | medium amount of rain (buffalos, prairie chickens, grasshoppers) |
| Desert | the driest ecosystem |
| tundra | cold, dry region - surface frozen all year long- tress cannot grow |
| forest | receives more rain than grasslands |
| rainforests | receives year round rain |
| Population | all the members of one species that live in an area of an ecosystem |
| What changes a population size? | Amount of food, water, and space |
| What do different populations form? | Community |
| Habitat | area or place where organism lives in an ecosystem |
| What does a habitat provide? | everything that an organism needs |
| What is a organism address? | A habitat |
| Each organism has a different job, role or ... | niche |
| What is the main energy source for life on earth? | Sunlight |
| Why are plants called producers? | Because they make their own food. |
| What are consumers? | organisms that eat other living things. |
| Herbivores | eat only plants |
| Carnivores | eat only animals |
| omnivores | eat both plants and animals |
| scavengers | feed on dead plants and animals |
| Where do animals eat or get eaten? | The foodchain |
| What begins a food chain? | Sunlight energy |
| What is the second part of the food chain? | producers (plants) |
| What would happen if an ecosystem had only producers and consumers? | Plants would use of soil and plants would die, animals would starve |
| Decomposers | digest waste and remains of dead plants and animals |
| Food web | made up of overlapping foodchains of an ecosystem |
| Events that affect food web | disease, storms, pollution, hunting |
| Saltwater ecosystems | coral reefs, deep seas |
| Freshwater ecosystem | Okefenokee swamp |
| both fresh and saltwater ecosystem | the Everglades |
| decay happens more quickly in what kind of temperatures? | warm temperatures |
| Decay happens slowly in what kind of temperatures? | cold temperatures |
| Moisture an plenty of oxygen | 2 things that help decomposers grow better and work faster |
| Why do you put food in a refrigerator? | Because the cold temp will keep the food from decaying quickly |
| Why do you cover food in a refrigerator? | TO keep down the amount of oxygen that can spoil food |
