Question 3

Living organisms

Answer 3

Any organism which can perform the seven processes of living.

Question 4

Interdependent organisms

Answer 4

Biotic factors which interact in their quest for energy and food, among other things. They rely on each other.

Question 5

Answer 5

Chlorophyll
Carbon Dioxide+Water➡️➡️➡️➡️➡️Glucose+Oxygen
Sunlight

Question 5

What do living organisms depend on to sustain life?

Answer 5

Energy

Question 6

What is the ultimate source of energy?

Answer 6

The sun is the ultimate source.

Question 7

What is radiant energy?

Answer 7

Radiant energy is the light and heat energy that radiates from the sun.

Question 8

Why are plants important to animals?

Answer 8

Animals cannot absorb radiant energy directly from the sun. They rely on plants to transform this energy into a form that they can use.

Question 8

How do plants absorb carbon dioxide?

Answer 8

Their leaves absorb carbon dioxide from the gases in the atmosphere.

Question 10

How do plants absorb radiant energy?

Answer 10

A special chemical in their cells, a pigment called chlorophyll absorbs radiant energy from the sun.

Question 11

How do plants absorb the water in soil?

Answer 11

They use their roots to absorb the water.

Question 12

What is photosynthesis?

Answer 12

It is the process by which green plants transform radiant energy, water and carbon dioxide into Glucose using a chemical called chlorophyll, which is also the green pigment in these plants.

Question 13

What is the word equation for photosynthesis?

Answer 13

Chlorophyll
Carbon Dioxide+water➡️➡️➡️➡️➡️ Oxygen+glucose
Sunlight

Question 14

What is needed for plants to perform the process of photosynthesis?

Answer 14

Carbon dioxide, water, and sunlight is needed.

Question 15

What is starch?

Answer 15

Starch is the compound formed by plants from glucose molecules. It is used to store potential energy to be used to perform the seven processes of life. Other animals that eat the plants gain this stored energy.

Question 16

What is cellulose?

Answer 16

Cellulose is the compound formed by green plants from glucose molecules. It is used to give the plant’s cell walls structure.

Question 17

What is a variable?

Answer 17

Variables are any factors that influence a scientific investigation.

Question 18

What are some examples of variables?

Answer 18

Mass, temperature, time, volume and light are variables.

Question 19

What is an independent variable?

Answer 19

It is the variable that the scientist chooses to change.

Question 20

What is a dependant variable?

Answer 20

The dependant variable is the variable that will change depending on the independent variable. It is the variable to be measured in an experiment.

Question 21

What are controlled variables?

Answer 21

They are the variables in an experiment that are needed to be kept the same for the experiment to be a fair one.

Question 22

What compounds are created from the simple sugar glucose?

Answer 22

Starch and cellulose are created.

Question 23

What is a fair test?

Answer 23

A fair test is a scientific investigation wherein all the variables are controlled.

Question 24

What is a practical investigation?

Answer 24

It is an investigation that aims to determine something

Question 24

How do you carry out a practical investigation?

Answer 24

Observe the world and ask questions Write a hypothesis Plan your investigation Conduct your investigation and record your findings Analyse your results and write a conclusion Evaluate your investigation

Question 25

What is a hypothesis?

Answer 25

It is a statement that gives a possible explanation to the question that you are investigating. It is a prediction of what you think will happen.

Question 26

How can energy be released from food?

Answer 26

It can be released by a series of chemical reactions.

Question 28

What is respiration?

Answer 28

Respiration is the process by which all living organisms release energy.

Question 30

Where does respiration occur?

Answer 30

All living organisms perform the process of respiration.

Question 32

What happens during respiration?

Answer 32

Plants and animals break down glucose and oxygen to produce carbon dioxide, water and energy. They release these substances back into the atmosphere.

Question 34

What is the word equation for respiration?

Answer 34

Glucose+oxygen➡️➡️➡️➡️➡️energy+carbon dioxide+water

Question 35

What are the reactants of a chemical reaction?

Answer 35

They are the things that are needed to perform a process.

Question 36

What are the products of a chemical reaction?

Answer 36

These are the things that are created or released during the chemical reaction.

Question 37

What is a resource required for respiration?

Answer 37

Oxygen.
