Chapter 31.1 Notes
  • Ecosystem is a community interacting with the environment. Includes all the living and nonliving factors.

  • Abiotic nonliving factors soil, sunlight, air, water….
  • Soil form from broken down rocks.

Ecology is the study of how living things interact with each other and with their environment.
  • Nitrogen is important because living things use it to make protein.
slide4
Cycles is the reusing of a natural resource.

  • Nitrogen cycle (plants get N mainly from the soil)
  • Oxygen-Carbon dioxide cycle

Biome a land area with a distinct climate and with specific type of plants an animals.

  • Desert -little precipitation and lizards
  • TemperateForest-biggesttemperaturerange
