conserved

Everyday

1. Protected and kept safe from damage or being wasted, like conserved forests or conserved water. tree →
2. (science) Staying the same in total, not being made or destroyed, as in "energy is conserved". tree →
3. (biology) Kept almost the same over a very long time in many living things, like a conserved gene. tree →

In the lessons

In science lessons, "mass is conserved" in a chemical reaction and "energy is conserved". In geography and everyday life it means saved or protected. Phrases: "energy is conserved", "conserved area", "conserved for future".

Examples

• In a reaction, mass is conserved: nothing is lost. tree →
• Energy is conserved; it just changes form. tree →
• The old painting was carefully conserved. tree →
• We conserved water by taking shorter showers. tree →
• The wetland is conserved for birds. tree →
• Some genes are conserved in humans and fish. tree →

Note

Past form of "conserve" (one r, ends in -ed). In science, "conserved" means the total amount stays the same: if you start with 100 g of reactants, you end with 100 g of products. Noun: conservation.
