Presentation on theme: "All organisms have the same basic needs:"— Presentation transcript:
1All organisms have the same basic needs: Necessities of LifeAll organisms have the same basic needs:FoodWaterAirShelter
23 groups: based on how organisms obtain their food Producers “Photosynthesis”are organisms that make their ownfood by using the sun’s energy,water and carbon dioxide to makeoxygen and glucose.Example: Plants
3Consumers “Eat” Examples: Animals are organisms that consume (eat) producers and other consumersto get energy.Examples: Animals
4Decomposers “Break Down” are organisms that breakdown dead matter or animalwastes to get energy.Examples:Fungus and Bacteria
5Water Cells are made up of 70% water Water is obtained from the fluids you drink and the foodyou eat.FACT: Water is so vital toour metabolism that we couldonly survive about three dayswithout it.
6Air “Photosynthesis” Oxygen, Carbon Dioxide, Nitrogen Most living things need oxygen for the chemicalprocesses that release energy from food.“Photosynthesis”6CO H2O C6H12O O2Plants, Algae and some Bacteria use carbondioxide to make oxygen.Light Energy
7“Cellular Respiration” C6H12O O CO H2O + ATPAnimals on land and in water use oxygen to makecarbon dioxide.
8Shelter All organisms need a “Protection” place to Live, whether in a large amount of spaceor on a single pore on thetip of your nose.
9Organisms often compete with each other fornutrients, living space andaccess to water and sunlightwhen the organism’senvironment is limited.

11G three days 3 Like most other organisms, your body is about ____________ water.C 70%4 How long can humans survive withoutdrinking water or other water-rich drinks?G three days
12B oxygen H carbon dioxide 5 In addition to making food, the process of photosynthesis makesB oxygen6 What part of air is most critical forphotosynthesis?H carbon dioxide
137 Because the amount of ____________ on Earth is limited, organisms oftencompete for resources.B space8 Which of the following is NOT a basicneed of all living things?F sunlight
149 A ______________ obtains food by eating other organisms.A consumer10 Bacteria are known as _____________ becauseof the way they obtain food.H decomposers
