| Question | Answer |
| A place where many types of organisms survive together | ecosystem |
| Living things | organisms |
| Organisms __ on each other and nonliving parts of the ecosystem to survive. | depend |
| Another name for living things | biotic factors |
| Another name for nonliving things | abiotic factors |
| Examples of biotic factors | squirrels, trees, bushes, grass, mouse, deer, insects |
| Examples of abiotic factors | sunlight, soil, air, water, rocks |
| Basic needs of all living things | food, water, shelter, air, space to grow or hunt |
| All of the basic needs together are called | resources |
| an organism's home | habitat |
| Conditions that make it hard for an organism to survive | fire, bad weather, changes to the habitats, poor weather conditions |
| The smallest part of an ecosystem | organism |
| a single living thing | organism |
| a group of the same species | population |
| All types of species living together | community |
| Living and nonliving together | ecosystem |
| ALL ecosystems on the planet | biosphere |
| When organizing an ecosystem, the largest part | biosphere |
| Organize an ecosystem from smallest to largest. | organism, population, community, ecosystem, biosphere |
| Another word for home | habitat |
| 2 types of habitats | terrestrial, aquatic |
| A habitat on land | terrestrial |
| A habitat in or near water | aquatic |
| Examples of terrestrial habitats | desert, forrest, rain forrist, city, mountain |
| Examples of aquatic habitats | lake, pond, river, stream, ocean, swamp |
| Ecosystems are classified by the amount of | water and climate |
| Organisms in ecosystems are connected by | what they eat |
| A group of the same type of organism | species |
| A group or organisms that makes their own food | producers |
| All __ are producers. | plants |
| Plants make their own food by a process called | photosynthesis |
| __ provide energy for the whole ecosystem. | plants |
| General term for organisms that eat other organisms | consumers |
| Name the 3 types of consumers | carnivores, herbivores, omnivores |
| Consumer that eats animals | carnivore |
| Consumer that eats only plants | herbivore |
| Consumer that eats both plants and animals | omnivore |
| Carnivores are also called __ because they hunt. | predators |
| The animals that carnivores hunt are called | prey |
| Shows how energy moves in an ecosystem | energy pyramid |
| The bottom level of an energy pyramid is filled with | producers |
| Energy is __ in each level as you go up by an exponent of 10. | lost |
| The farther up the energy pyramid that you go, the __ food (energy) that you have. | less |
| The level above the producers on the energy pyramid is filled with | first level consumers |
| Things that could cause a body to lose or use up energy | moving, eating, breathing, heart beating |
| If the bottom level of a 3 layer energy pyramid had 1000 kilocalories, how many would the top layer have? | 10 kilocalories |
| ALL organisms in an ecosystem need __ to survive. | producers (plants) |
| Shows connections between organisms in an ecosystem | food web |
| The links in a food web show where __ __ is passed. | food energy |
| Arrows in a food web point how? | from a food source to the organism that eats it |
| If a herbivore eats a plant, it __ energy. | gains |
| If a carnivore eats an animal, it __ energy. | gains |
| Animals that eat dead animals | scavengers |
| Organisms that eat what scavengers leave behind | decomposers |
| Examples of decomposers | mushrooms, bacteria, some insects |
| Known as nature's recyclers | decomposers |
| 2 things that decomposers do | 1. return food energy from dead organisms back to the ecosystem 2. make soil richer |
| Too many of one species in an ecosystem | overpopulation |
| Highest number of individual plants or animals that can live in an ecosystem and share the same resources | carrying capacity |
| Examples of limiting factors | food, shelter, space, water, number of predators and prey, presence of disease |
| Carrying capacity can change based on the | limiting factors |
| What is the difference between a food web and a food chain? | food chain - shows how one organism links with another then links to another, then links to another... food web - overlapping food chains in an ecosystem |
| All organisms depend on other organisms for __. | survival |
| When one organism depends on another for its survival | symbiosis |
| 3 types of symbiotic relationships | mutualism, parasitism, commensalism |
| A symbiotic relationship where both of the two organisms benefit or help each other | mutualism |
| A symbiotic relationship where one organism causes harm to the other organism | parasitism |
| A symbiotic relationship that helps one organism but does not affect the other | commensalism |
| Examples of mutualism | bees pollinating plants rhino with birds that eat insects off of back |
| Examples of parasitism | ticks on a person ticks on a dog head lice on a person mosquito on a person |
| Examples of commensalism | large tree providing shade for smaller plants barnacles on a whale remoras ona shark |
| Name for the organism that takes food from the organism that it is living on | parasite |
| Name for the organism that the parasite is living on | host |
| Name of the law where the mass of a particular thing stays the same no matter what changes it goes through | conservation of mass |
| Matter cannot be ... | created or destroyed |
| Examples of cycles in nature | nutrient, water, rock, carbon, nitrogen |
| Plants and animals need __ to grow and repair themselves | nitrogen |
| Where do plants get the nitrogen that they need? | from the soil |
| Where do animals get the nitrogen that they need? | from eating plants |
| What changes nitrogen in the air to ammonia and nitrates that plants can use? | bacteria |
| What powers the carbon dioxide/oxygen cycle? | photosynthesis and respiration |
