This slows down photosynthesis and plant growth

Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as , or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build complex molecules such as and .

It is fairly easy to show that plants produce oxygen and starch in photosynthesis

The global rise of urbanization and industrialization has led to an increase in urban air pollution.

Environmental problems are often emotive—under what circumstances should we maintain a detached relationship with the subject matter under investigation?

(In other words, ourcurrent oxygen-rich atmosphere was generated as a by-product ofphotosynthesis, and without it life as we know it would not bepossible.)

When a plant is eaten the carbon it containspasses to the consumer e.g a cow grazes on grass, and as we enjoy oursteak so the carbon is transferred to us.
