Interactions within the Enviroment Study cards
| Question | Answer |
|---|---|
| What is the definiton of a biotic element? | Any living thing found in the enviroment |
| What is the definiton of a abiotic element? | Any non-living thing found in the enviroment |
| What is the definiton of a organism? | A living thing |
| What is the definiton of a micro organism? | A living thing that is small and must be viwed with the help of a micro scope |
| What is the definiton of a species? | A group of similar organisms that can mate and reproduce more of the same type of organism. |
| What is the definiton of a population? | A group of organisms of the same species in a givin area |
| What is the definiton of a habitat? | The enivroment where an organism lives |
| What is the definiton of a ecosystem? | A network of interactions that link the living and non-living parts of the envirmoment. |
| What is the definiton of a community? | A community is made up of populations of diffrent species in a givin area that interact some way. |
| What is the definiton of ecology? | The branch of biology that studys the interactons bettween the organisms and thier enviroment. |
| What is the definiton of a nutrient? | A nutriant is a substance that an organism needs to live and grow |
| Why is sunlight important? | It provids energy that makes life possible,it also provids warmth for some animals.Also amounts of sunlight indicate sesonal events.After one animal eats a plant, the energy is then transford from the plant to the animal. |
| Why do plants need sunlight? | Plants need energy to grow and repruduce. Sunlight is used by plants to make sugars.This proccese is called photosynthesis. |
| Why is air important? | Many organisms breath in air to obtain oxagyn needed to preform life processes.All organisms depend on oxagyn to produce plants |
| Why do plants need air? | Plants absorb carbon dioxide to produce shugars. Plants also produce oxagyn |
| Why is water important? | All organisms need it to survive.Animalls need it to digest food and to form body fluids e.g. blood.Many organisms live in water. the water contains desolved oxgyn and carbon dioxide, there fore many plants and animals absorb oxagyn from the water. |
| Why is food important? | It provids nutrients to plants and animals to grow and maintain itself. Animals stay healthy by eating the nutreints in food. |
| Why is an ideal temperature range important? | Most organisms need an ideal temperature rnage in wich they can live. if it to cold or to hot, the organism may not be able to survive.The temperature can be affected by interactions of sunlight, soil, air, and water. |
| What is compatition? | Occurs when more than one organism tries to obtain the same basic resoursesin the same habitat. e.g. plants can compete for the same water, sunlight, nutriants. |
| What happens in compatition? | In compatition one organism usually "wins" and another "loses". With limited resourses, some plants may grow small, thin or may die while others survive and grow strong.Compatition controls population size,it limits the nuber of organisms that can survive |
| What is preditation? | A preditor is an animal that hunts for food. "prey" is hunted by the preditor. The population of preditors will affect the population of the prey.This can also affect plants, more prey mean less plants, less prey mean more plants. In preditation, one orga |
| What is mutualism? | Interactions bettween individuals of diffrent speccies that benifits both individuals. eg. bee visiting flower- bee takes necture from flower for food- then picks up pollen from flower- while doing so- pollen transford from one flower to the next allows f |
| what is a decomposer? | An organism that consumes and breaks down dead organisms or waste matter so they can be reused in an ecosystem |
| Why are decomposeres important? | They break up complex chemicals into simpler substances that other organisms can use as food. |
| What is a detrivore? | An organism that feeds on large parts of decaying plant and nimal matter and waste on material. |
| What is a producer? | an organism that contain chlorophyll and is able to make its own food. Chlorophyll is a green substance that allows plants to capture energy from the sun. photosynthesis describes the process where plants use energy from the sun. photosynthesis= carbon di |
| What is a consomer? | An organism that cannot produce its own food energy from sunlight therefore relies on other organisms to consume for food in order to get "captured energy". |
| what are the diffrent types of consomers? | 1. herbivors- plant eaters 2. carnivors- meat eaters 3. omnivors- plant and meat eaters 4. scavengers- eat already dead animals |
| what is a food chain? | An organized system that shows a feeding pathway. They are simple diagrams that trace the flow of matter and food energy in an ecosystem. Arrows in a food chain indicate the direction in wich the energy is being transford. |
| What is a food web? | An organized system made up of many intersecting food chains. It connects each organism with all of the organisms it eats and all of the animals it eats. It is formed because rarley more then one animal eats one type of food. |
