  31. Ecosystem – A community of living organisms interacting with each other and with their non-living environment (like soil, air, and water) within a certain area.

  32. Population – A group of individuals of the same species living in the same area at the same time, capable of interbreeding.

  33. Atom – The smallest unit of matter that retains the properties of an element. Atoms combine to form molecules.
