Chapter 31 1 notes

Chapter 31.1 Notes

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

  • Biotic living factors plants, animals, fungi…

  • Abiotic nonliving factors soil, sunlight, air, water….

  • Soil form from broken down rocks.


Chapter 31

  • 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.


Chapter 31

Cycles is the reusing of a natural resource.

  • Water cycle

  • Nitrogen cycle (plants get N mainly from the soil)

  • Oxygen-Carbon dioxide cycle


Chapter 31 2 notes

Chapter 31.2 Notes

  • Succession is the changes that take place in a community as it gets older.

  • Climax community is the last or final stage of succession.


Chapter 31

  • Forest community succession… Bare soil, field of weeds, field of small plants, Forest


Chapter 31

  • Lake, pond, marsh, dry land.


Chapter 31 3 notes

Chapter 31.3 Notes

  • Light and temperature are 2 nonliving (abiotic) factors that are not cycled.

  • Precipitation is water in the air that falls to the earth as rain or snow.

  • Climate is the average of light, temperature and precipitation over many of years.


Chapter 31

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

  • Tropical rain forest- a lot of rain (200cm/year) about 6 feet.

  • Grassland- gophers are common

  • Desert -little precipitation and lizards

  • TemperateForest-biggesttemperaturerange

  • Taiga- moose are common

  • Tundra- polar bears…10-15cm of precipitation/year.
