## Step 1<br />The first question is about the percentage of irrigation water that reaches the roots of plants. The correct answer is 'Efficiency', which is the measure of how much of the irrigation water actually reaches the roots of the plants.<br /><br />## Step 2<br />The second question is about organisms that damage crops. The correct answer is 'Biological pests', which are organisms that cause harm to crops.<br /><br />## Step 3<br />The third question is about the process where chemicals build up in the tissues of organisms over time. The correct answer is 'Bioaccumulation', which is the process where chemicals accumulate in an organism over time.<br /><br />## Step 4<br />The fourth question is about the method of growing plants in water rather than soil. The correct answer is 'Hydroponics', which is a method of growing plants in water rather than soil.<br /><br />## Step 5<br />The fifth question is about plants that have had their DNA altered. The correct answer is 'GMO', which stands for Genetically Modified Organism.<br /><br />## Step 6<br />The sixth question is about chemicals that kill pests. The correct answer is 'Pesticides', which are chemicals used to kill pests.<br /><br />## Step 7<br />The seventh question is about crops that completely cover the soil. The correct answer is 'Cover crops', which are crops that cover the soil completely.<br /><br />## Step 8<br />The eighth question is about a type of irrigation using sprinklers. The correct answer is 'Center pivot irrigation', which is a type of irrigation system that uses sprinklers.
