What Science

1. What are the only organisms that can make their own food?

- Green Plants

2. Photosynthesis is the process that occurs when plants use chlorophyll and sunlight to convert water and carbon dioxide into food.

3. The role that chlorophyll plays in the life of a plant is:

- It gives plants their green colour

- And it traps energy from sunlight so green plants can make food for themseleves

4. Herbivore is a plant-eating animal

Carnivore is a meat eating animal

Omnivore is an animal that eats both plants and animals.

5. Decomposers break down plant and animal matter into nurtients

- this process helps return nutrients to the soil

6, Two examples of decomposers are:

- fungi

- bacteria

7. Difference between a food web and a food chain is:

- Food Web is how plants and animals in a habitat connect through food

- Food Chain is food energy going from one living thing to another.

8. Dead animals are important to soil because:

- when the animal dies, decomposers break down the dead matter

- and it becomes part of the soil.

- the soil then provides nutrients for the plants that grow in the garden

- which then begins the food chain

9. Five examples of natural disasters are:

- Hurricanes

- Tornadoes

- Floods

- Droughts

- Ice Storms

10. Sudbury improved its land by:

- they started planting trees

- improving the soil

11. Acid rain happens becasue:

- its a form of pollution that comes mostly from power-plant smokestacks.

- power plants burn coal and put chemicals into the air.

- these chemicals react wiht the water in couds

- this produces mild acid

- when rain falls from these clouds it carries the acid to the ground

12. Two examples of the damage that acid rain can do are:

- buildings wear down

- Railway tracks rust faster

13. An example from Australia where an species was added is:

- An rabbit was brought there

- they were so well suited that they rapidly increased in...
