Almost all living things ultimately get their energy from the sun. In a process called photosynthesis, plants, algae, and some other organisms capture the sun's energy and use it to make simple sugars such as glucose. Most other organisms use these organic molecules as a source of energy. Organic materials contain a tremendous amount of energy. As food, they fuel our bodies and those of most other creatures. In such forms as oil, gas, and coal, they heat our homes, run our factories and power our cars.

Photosynthesis begins when solar energy is absorbed by chemicals called photosynthetic pigments that are contained within an organism. The most common photosynthetic pigment is chlorophyll. The bright green color characteristic of plants is caused by it. Most algae have additional pigments that may mask the green chlorophyll. Because of these pigments, algae may be not only green but brown, red, blue or even black.

In a series of enzyme-controlled reactions, the solar energy captured by chlorophyll and other pigments is used to make simple sugars, with carbon dioxide and water as the raw materials. Carbon dioxide is one of very few carbon- containing molecules not considered to be organic compounds. Photosynthesis then converts carbon from an inorganic to an organic form. This is called carbon fixation. In this process, the solar energy that was absorbed by chlorophyll is stored as chemical energy in the form of simple sugars like glucose. The glucose is then used to make other organic compounds. In addition, photosynthesis produces oxygen gas. All the oxygen gas on earth, both in the atmosphere we breathe and in the ocean, was produced by photosynthetic organisms. Photosynthesis constantly replenishes the earth's oxygen supply.

Organisms that are capable of photosynthesis can obtain all the energy they need from sunlight and do not need to eat. They are called autotrophs. Plants are the most familiar autotrophs on land. In the ocean, algae and bacteria are the most important autotrophs. Many organisms cannot produce their own food and must obtain energy by eating organic matter. These are called heterotrophs.

Hầu như tất cả các sinh vật sống về cơ bản nhận năng lượng từ mặt trời. Trong một quá trình gọi là quang hợp, thực vật, tảo và một số sinh vật khác thu năng lượng của mặt trời và sử dụng nó để tạo ra các loại đường đơn giản như glucose. Hầu hết các sinh vật khác sử dụng các phân tử hữu cơ này như một nguồn năng lượng. Vật liệu hữu cơ chứa một lượng năng lượng rất lớn. Là thức ăn, chúng cung cấp dinh dưỡng cho cơ thể chúng ta và của hầu hết các sinh vật khác. Trong các hình thức như dầu, khí đốt và than đá, chúng làm nóng nhà của chúng ta, điều hành các nhà máy và cung cấp năng lượng cho xe hơi của chúng ta.

Quang hợp bắt đầu khi năng lượng mặt trời được hấp thụ bởi các hóa chất gọi là sắc tố quang hợp có trong một sinh vật. Các sắc tố quang hợp phổ biến nhất là diệp lục. Màu xanh tươi đặc trưng của cây là do nó gây ra. Hầu hết các loại tảo có các sắc tố bổ sung có thể che lấp diệp lục xanh. Do các sắc tố này, tảo có thể không chỉ có màu xanh mà còn có màu nâu, đỏ, xanh hoặc thậm chí là đen.

Trong một loạt các phản ứng kiểm soát enzyme, năng lượng mặt trời thu được từ diệp lục và các sắc tố khác được sử dụng để tạo ra các loại đường đơn giản, với carbon dioxide và nước làm nguyên liệu. Carbon dioxide là một trong số rất ít các phân tử chứa carbon không được coi là hợp chất hữu cơ. Quang hợp sau đó chuyển đổi carbon từ một chất vô cơ thành dạng hữu cơ. Điều này được gọi là cố định carbon. Trong quá trình này, năng lượng mặt trời được hấp thụ bởi chất diệp lục được lưu trữ dưới dạng năng lượng hóa học dưới dạng đường đơn giản như glucose. Glucose sau đó được sử dụng để tạo ra các hợp chất hữu cơ khác. Ngoài ra, quang hợp tạo ra khí oxy. Tất cả khí oxy trên trái đất, cả trong bầu khí quyển chúng ta hít thở và trong đại dương, được tạo ra bởi các sinh vật quang hợp. Quang hợp liên tục bổ sung nguồn cung cấp oxy cho trái đất.

Các sinh vật có khả năng quang hợp có thể thu được tất cả năng lượng mà chúng cần từ ánh sáng mặt trời và không cần ăn. Chúng được gọi là tự động. Thực vật là sinh vật tự dưỡng quen thuộc nhất trên đất liền. Trong đại dương, tảo và vi khuẩn là những sinh vật tự dưỡng quan trọng nhất. Nhiều sinh vật không thể tự sản xuất thức ăn và phải lấy năng lượng bằng cách ăn chất hữu cơ. Chúng được gọi là dị dưỡng.
