• For the first description, "a substance that provides nourishment essential for growth and the maintenance of life", the term "nutrient" fits as nutrients are substances that organisms need for growth, repair, and maintenance.
• For the second description, "a process used to solve pest problems while minimizing risks to people and the environment", "Integrated Pest Management (IPM)" is the correct term as it is a strategy that aims to control pests in an environmentally - friendly and human - safe way.
• For the third description, "includes the parts of plant foods your body can't digest or absorb", "dietary fiber" is the appropriate term. Dietary fiber is the indigestible part of plant foods.
