All organisms have the same basic needs: Food Water Air Shelter
ProducersPhotosynthesis are organisms that make their own food by using the suns energy, water and carbon dioxide to make oxygen and glucose. Example:Plants 3 groups: based on how organisms obtain their food
Consumers Eat are organisms that consume (eat) producers and other consumers to get energy. Examples: Animals
Decomposers Break Down are organisms that break down dead matter or animal wastes to get energy. Examples: Fungus and Bacteria
Cells are made up of 70% water Water is obtained from the fluids you drink and the food you eat. FACT: Water is so vital to our metabolism that we could only survive about three days without it.
Oxygen, Carbon Dioxide, Nitrogen Most living things need oxygen for the chemical processes that release energy from food. Photosynthesis 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 Plants, Algae and some Bacteria use carbon dioxide to make oxygen. Light Energy
Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O + ATP Animals on land and in water use oxygen to make carbon dioxide.
All organisms need a place to Live, whether in a large amount of space or on a single pore on the tip of your nose. Protection
Organisms often compete with each other for nutrients, living space and access to water and sunlight when the organisms environment is limited.
1Plants are known as __________ because of the way they obtain food. B producers 2Which of the following living things is a producer? H an alga Necessities Of Life Mini Assessment
3Like most other organisms, your body is about ____________ water. C 70% 4How long can humans survive without drinking water or other water-rich drinks? G three days
5In addition to making food, the process of photosynthesis makes B oxygen 6What part of air is most critical for photosynthesis? H carbon dioxide
7Because the amount of ____________ on Earth is limited, organisms often compete for resources. B space 8Which of the following is NOT a basic need of all living things? F sunlight
9A ______________ obtains food by eating other organisms. A consumer 10Bacteria are known as _____________ because of the way they obtain food. H decomposers
