1 All organisms have the same basic needs: Food Water Air Shelter

2 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

3 Consumers Eat are organisms that consume (eat) producers and other consumers to get energy. Examples: Animals

4 Decomposers Break Down are organisms that break down dead matter or animal wastes to get energy. Examples: Fungus and Bacteria

5 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.

6 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

7 Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O + ATP Animals on land and in water use oxygen to make carbon dioxide.

8 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

9 Organisms often compete with each other for nutrients, living space and access to water and sunlight when the organisms environment is limited.

10 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

11 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

12 5In addition to making food, the process of photosynthesis makes B oxygen 6What part of air is most critical for photosynthesis? H carbon dioxide

13 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

14 9A ______________ obtains food by eating other organisms. A consumer 10Bacteria are known as _____________ because of the way they obtain food. H decomposers
