2

What is a tube worm?

A worm that lives at the bottom of the sea near hydrothermal vents.

3

Name 2 types of chemosynthetic bacteria

sulfur bacteria

nitrogen bacteria

4

What is usually a reactant of chemosynthesis?

carbon dioxide

5

Bacteria that produce glucose via chemosynthesis are called...

chemosynthetic bacteria

6

Which type of chemosynthetic bacteria are usually found in soil and the roots of plants?

nitrogen bacteria

7

Chemosynthesis requires energy to produce glucose. Where does this energy come from?

chemical reactions

8

What sort of relationship do tube worms and sulfur bacteria have?

A symbiotic or mutualistic relationship

9

Sulfur bacteria live inside tube worms. Why does this benefit both organisms?

It is a safe place for bacteria to live.

The bacteria produce glucose for the tube worms

10

Which type of chemosynthetic bacteria are usually found near deep sea volcanic vents?

sulfur bacteria

11

How do sulfur bacteria produce glucose?

They react carbon dioxide and water from the sea with hydrogen sulfide from hydrothermal vents.

They also use some compounds provided by tube worms.

12

What is the main product of chemosynthesis?

glucose

13

What type of nutrient is glucose?

A carbohydrate

14

What is chemosynthesis?

When an organism uses chemical reactions to produce glucose.

15

Organisms use glucose (carbohydrate) for...

energy

16

In what sort of places are chemosynthetic bacteria found?

The bottom of the sea near hydrothermal vents.

In soil and the roots of some plants

17

What is meant by reactants?

The things that are reacted together in a chemical reaction to make a product
