| Producers rely on sunlight and this other abiotic factor to carry out photosyntheses | Carbon Dioxide |
| Most of the nitrogen we consume comes from what we eat. They originally got it from what source | The soil |
| Symbiotic Relationship where only one animal is affected | Commensalism |
| T or F the law of conservation of matter states that energy cannot be created or destroyed | True |
| T or F A food chain is the feeding relationships among all of the organism in an ecosystem | False |
| Why do plants that grow in the tundra have shallow root systems that don't grow very deep due to the conditions of the soil? | They can't grow through the permafrost |
| In which biome would you expect to find a layer of permafrost | tundra |
| Which biome would your find a cactus? | Desert |
| How is a tundra biome similar to a desert biome | both biomes have little precipitation. |
| What determines the biome? | The climate that exists there |
| Which ecosystem would have the greatest biodiversity? | tropical rainforest |
| What best describes the number and variety of organisms in an area? | biodiversity |
| What describes a consumer? | an organism that gets its energy by eating plants or animals. |
| What describes a producer? | Uses sunlight to produce its own food (plants) |
| A wolf eats a rabbit and then a hawk takes it. parasitism, commensalism, mutualism, predation, or competition | competition |
| A tick on a dog parasitism, commensalism, mutualism, predation, or competition | parasitism- tic benefits and dog hurt |
| A polar bear searches the ice for a seal to eat parasitism, commensalism, mutualism, predation, or competition | predation |

| If the population of hawks increase over several years, what would happen to the population of snakes that hawks eat | It would decrease |
| Lily pads, seaweed, insects, frogs, hawks, water, soil, oxygen and sunlight make up an _______________ | ecosystem |
| What is the struggle for organisms to survive while they attempt to survive using the same limited resources is called __________ | competition |
| When the prey population goes up the predator population would go ___________ | up |
| Which biome would have many months with little to no rain and temperatures around 86 degrees | desert |
| If all energy can be traced back to the sun, than in order for the snake to get energy from the sun it must..... | eat an animal that eats a plant or other producer |
| What is are abiotic factors in an ecosystem? | living things |
| The cookoo bird lays its eggs in another birds nest. When the baby hatches it pushes all the other eggs out of the nest. How does this impact ecosystem? | It is parasitism. This increases the chances that the cookoo bird will survive and possibly decrease the population of another bird. |
