What type of material is used to promote plant growth by providing nutrients?

Fertilizer is specifically designed to promote plant growth by supplying essential nutrients that plants need to thrive. These nutrients typically include macronutrients like nitrogen, phosphorus, and potassium, as well as various micronutrients that contribute to overall plant health. When fertilizer is applied to the soil or directly to plants, it enhances their ability to grow by improving their nutrient uptake and promoting vibrant, successful growth.

This contrasts with other options. Herbicides are substances used to control unwanted plants, often referred to as weeds, and do not provide nutrients. Pesticides target a variety of pests, including insects and other organisms that could damage plants, but they do not aid in plant nutrition. Fungicides are aimed at controlling fungal diseases and also do not contribute nutrients for plant growth. Thus, fertilizer stands out as the correct choice because its primary purpose is to enrich the soil and support healthy plant development.
