1. Environmental Science Do Now 9-22-17
Do Now: Take your Do Now sheet and your article on the human impacts on the biogeochemical cycles.
Give one example of a human action that impacts each biogeochemical cycle (hydrological, carbon, nitrogen, and phosphorus).

2. Environmental Science Do Now 9-22-17 Key
Hydrological Cycle: Humans dump harmful chemicals into bodies of water polluting the water

3. Environmental Science Do Now 9-22-17 Key
Nitrogen Cycle: Humans put too much nitrogen-containing fertilizer on crops; some of the fertilizer runs off into bodies of water causing the algae in the water to overgrow and deplete the water’s dissolved oxygen supply.

4. Environmental Science Do Now 9-22-17 Key
Carbon Cycle: Humans burn too many fossil fuels (gas, oil, petroleum, etc.) to operate vehicles and factories which releases harmful pollutants into our atmosphere.

Phosphorus Cycle: Humans put too much phosphorus-containing fertilizer on crops; some of the fertilizer runs off into bodies of water causing the algae in the water to overgrow and deplete the water’s dissolved oxygen supply.

12. copyright cmassengale
What is Ecology??
The study of interactions that take place between organisms and their environment.
It explains how living organisms affect each other and the world they live in.
copyright cmassengale

13. copyright cmassengale
Habitat & Niche
Habitat is the place a plant or animal lives
Niche is an organism’s total way of life
copyright cmassengale

14. The Nonliving Environment
Abiotic factors- the nonliving parts of an organism’s environment.
Examples include air currents, temperature, moisture, light, and soil.
Abiotic factors affect an organism’s life.
copyright cmassengale

15. The Living Environment
Biotic factors- all the living organisms that inhabit an environment.
All organisms depend on others directly or indirectly for food, shelter, reproduction, or protection.

22. Levels of Organization
Ecologists have organized the interactions an organism takes part in into different levels according to complexity.
copyright cmassengale

23. 1st Level of Organization
Organism: An individual living thing that is made of cells, uses energy, reproduces, responds, grows, and develops
copyright cmassengale

24. 2nd Level of Organization
Population: A group of organisms, all of the same species, which interbreed and live in the same place at the same time.
copyright cmassengale

25. 3rd Level of Organization
Biological Community: All the populations of different species that live in the same place at the same time.
copyright cmassengale

26. 4th Level of Organization
Ecosystem: Populations of plants and animals that interact with each other in a given area with the abiotic components of that area. (terrestrial or aquatic)
copyright cmassengale

27. 5th Level of Organization
Biosphere: The portion of Earth that supports life.
copyright cmassengale

28. copyright cmassengale
The Biosphere
Life is found in air, on land, and in fresh and salt water.
The BIOSPHERE is the portion of Earth that supports living things.

34. Seed Germination Lab – Day #1
Today you will set up your seed germination lab by:
Deciding which independent variable you will investigate
Write a scholarly hypothesis that you will be able to test
List ALL of the materials you will need
Write the procedures you will follow to test your hypothesis
Set up the lab
