Question 8

Ingestion

Answer 8

Take (in foods), into our body.

Question 9

Ecology

Answer 9

The study of environment.

Question 10

Biotic Factors

Answer 10

Living Factors in the environment.

Examples: bacteria, worms, birds, plants, snakes etc.

Question 11

Abiotic Factors

Answer 11

Non-living factors in the environment.

Examples: water, tempature, pH, salinity, light intensity

Question 12

Organisms

Answer 12

A living thing.

Question 13

Optimal range

Answer 13

Used to describe best conditions within the tolerance range in which the species are at their healthiest state.

Question 14

Ecosystem

Answer 14

When abiotic factors and biotic factors are together.

Question 15

Photosynthesis

Answer 15

Plants use the sun’s light and turn it into energy.

Question 16

Community

Answer 16

All of the different populations living in the same place at the same time.

Question 17

Introduced species

Answer 17

An introduced species is one that has been released into an ecosystem in which it does not occur naturally.

Question 18

Steps of the water cycle

Answer 18

1. Transpiration or Respiration or Evaporation
2. Condensation
3. Precipitation
4. Run-off

Question 19

Independent Variable

Answer 19

What we are changing to observe its effect on another variable.

Examples: Salinity level/amount of salinity

Question 20

Aim

Answer 20

An aim is what the experiment is supposed to accomplish.

Example: To find the optimal range of salinity that coastal grass and inland grass can tolerate.

Question 21

Hypothesis

Answer 21

A hypothesis is what you think is going to happen (a suggested explanation that is tested) in an experiment.

Example: If we increase the salinity level, the germination of the seeds will decrease.

Question 22

Results

Answer 22

Results are the details or data that are recorded in an experiment after the testing.

Example: The inland seed could grow in water with no salt or 2 m/L in it. The coastal could only grow in water with a salinity level of 3 m/L

Question 23

Conclusion

Answer 23

A conclusion is the ending statement in which you describe if your hypothesis was right or wrong and that sums up the experiment. And if it was wrong, you describe what actually happened. The conclusion of an experiment relates to the stated aim.

Question 24

How was this Investigation made a fair test?

Answer 24

We made it a fair test because there were multiple controlled variables which will make it possible to measure the only dependent variable and to make only one independent variable.

Question 25

Dependent Variable

Answer 25

A variable that is expected to change when the independent variable is changed. It is observed or measured during the experiment.
