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). copyright cmassengale

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

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. copyright cmassengale

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. copyright cmassengale

Environmental Science Do Now 9-22-17 Key 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. copyright cmassengale

Organisms and Their Environment copyright cmassengale

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

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

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

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. copyright cmassengale

What are the Simplest Levels? Atom Molecule Organelle Cell Tissue Organ System copyright cmassengale

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

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

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

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

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

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

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. copyright cmassengale
