Fertilizer is a substance added to soil to provide essential nutrients that may be lacking for plant growth. This can include nutrients such as nitrogen, phosphorus, and potassium, which are vital for healthy plant development. Fertilizers can come in various forms, such as organic (manure, compost) or synthetic (chemical-based).
Fertilizers contain many different nutrients that aid in plant growth, and these nutrients are what plants absorb, through osmosis, to increase their speed of growth and quality. When there usually isn't a sufficient amount of nutrients, fertilizers are added to make up for this lack of necessity. The amount and quality of plant growth is called the "crop yield".
Humans lack the necessary enzymes in their digestive system to break down the cellulose in grass, making it difficult to extract nutrients from it. Additionally, the cellulose in grass is difficult for humans to digest compared to other sources of nutrients like fruits and vegetables.
Odor is a human sense (or an animal sense), if you lack the organs for detecting it, then a substance is "odorless" ... to you. Note that (for us mammals) a substance must be in vapor form to be detected, thus solids lack odor in general, while heating intensifies odor.
Non-living entities such as rocks, air, or water cannot metabolize nutrients as they lack the necessary biological processes and machinery to utilize and break down organic molecules for energy. Metabolism is a characteristic of living organisms that enables them to convert nutrients into energy through various biochemical pathways.
A person of no substance typically refers to someone who lacks depth, importance, or integrity. They may be superficial, lack meaningful contributions or qualities, and have little impact or value in various aspects of life.
Substance is important because it defines the essential character or nature of something. It provides the foundation on which things are built or developed. Without substance, things lack depth, meaning, or value.

Two factors that influence a region's photosynthetic productivity are the availability of sunlight and the presence of nutrients. Sunlight is crucial for photosynthesis as it provides the energy needed for the process. Nutrients, such as nitrogen and phosphorus, are essential for plant growth and photosynthetic activity. Lack of either sunlight or nutrients can limit photosynthetic productivity in a region.
Vitamins A and D are typically added to fat free milk. These are known to help aid in absorbing nutrients in the milk, especially calcium. Vitamin D is added in effort to supplement lack of sun exposure in most people.
Lack of protein and nutrients.

None, all nutrients can easily be found in foods other than meat.
A lack of vital nutrients can cause or increase Fibromyalgia symptoms.

Empty calories provide energy but lack essential nutrients such as vitamins, minerals, and fiber. Examples include sugary beverages, candy, and refined grains. Consuming too many empty calories can lead to nutrient deficiencies and weight gain.
