Phosphates - GCSE Biology Definition

Phosphates are chemical compounds that contain the element phosphorus, which is an essential nutrient for all living things. Phosphates are biologically important because they are part of molecules such as DNA and ATP, which are vital for storing genetic information and providing energy in cells. Plants absorb phosphates from the soil, and phosphates are commonly added to fertilisers to promote plant growth. In ecosystems, phosphates cycle through soil, water, and living organisms in a process called the phosphorus cycle. However, excess phosphates in water bodies can lead to problems such as algal blooms, which reduce oxygen levels and harm aquatic life.
