| Question | Answer |
|---|---|
| What is and ecosystem? | A place where many types of organisms survive together. |
| Organisms depend on each other and what to survive? | nonliving parts of the ecosystem to survive |
| What are the abiotic factors of an ecosystem? | nonliving parts of the ecostym to survive(ex:sunlight soil air water rocks) |
| what are the basic needs of all living things? | food water shelter air and space to grow or hunt (natural rescources) |
| what is a habitat? | an organism's home |
| what are examplesof things that make it hard for the organism to survive? | bad weather,changes to the habitats,poor weather condition |
| what is a population? | a group of same species |
| what is a community? | all types of species/living things |
| what is an ecosystem? | living and nonliving together |
| what is the bioshpere? | all the ecosystems on planet |
| what is a terrestrial habitat? | a habitat on land |
| what is an aquatic habitat? | a habitat in or near water |
| ecosystems are classified by what? | ammount of water and climate |
| organisms in an ecosystem are connected by how? | what they eat |
| what is a species? | all of the same type of organism |
| what type of organisms make their own food? | producers |
| how do producers make food for themselves? | a proscess called photosyntesis |
| what important role do producers have? | the provide food energy for the whole ecosystem |
| what are consumers? | organism that get there energy by eating other organisms |
| what are the types of consumers? | carnivores(eat other animals)herbivores(eat plants)omnivores(eat both plants and animals) |
| what is an energy pyramid? | thing that shows how energy moves in an ecosystem |
| what is lost in each level going up? | energy(moving,eating,bodily procsess all us up energy) |
| all organisms in an ecosystem need what to survive? | producers |
| what are food webs? | tings that show connections between organisms in an ecosystem(links in the web show where food energy is passed. ex:mouse->snake) |
| what is a scavenger? | animal that eats dead animal |
| what are decomposers? | teturn food energy from dead organism back to ecosystem,thus making the soil richer |
| what is over population? | too many of one species in an ecosystem |
| what is carrying capicity | highest number of individual plants or animals that can live in an ecosystem and share those rescources |
| what are the limithing factors? | food,shelter,space,water,numbers of predators and prey,precsence of desiease |
| what are the three types of symbiosis? | mutualism(relationship helps both organisms)parisitism(organism gets benifited;other gets harmed)commenalism(relationship helps one organism;other dosn't get help or harm) |
| what is a parisite? | organism thate takes food from organism by living on its host |
| what is conservation of mass? | the mass of a certain thing stays the same no matter what changes it goes through,so matter cannot be created or destroyed |
| what are esamples of nature's cycles. | nutrients cycle,water cycle,rock cycle,carbon cycle |
| plants and animals need what to repair themselves? | nitrogen |
| how do plants get nitrogen? | from soil |
| what changes nitrogen in the air to ammonia and nitrates that plants can use? | bacteria |
| how much percent of nitrogen is in the air? | seventy-eight percent |
