Ecology Notes

Biotic Something that is living or was once living. Examples: Bones, eggs, all plants, all animals

Abiotic Something that is not living and never was living. Examples: Rocks, water, air, fire, soil

Multi-Cellular An organism that is made up of many cells. Examples: All animals, humans, all plants

Unicellular An organism that is made up of a single cell. Example: Paramecium, amoeba, euglena

Sexual Reproduction Processes in which two parents contribute genes form a new Individual . Example: You, Trees, cats, dogs, bushes, flowers, most bugs

Asexual Reproduction Reproduction involving one parent organism with new organisms being identical to the parent. Example: Skin cells, bone cells, worms, paramecium, amoeba, euglena, bacteria

1. All living things Have cells Some organisms are made up of more than one cell and some are made up of just one cell (uni-cellular).

2. All living things sense and respond to change. When something changes in an organisms environment, that organism will be able to sense and respond to that change.

3. All living things Reproduce Some organisms reproduce Asexually or Sexually

4. ALL LIVING THINGS HAVE DNA DNA provides instructions for making molecules called PROTIENS which determine an organisms characteristics.

5. All living things use Energy Living things use energy to make food, break down food, and move materials in and out of cells.

6. All living things Grow and develop Unicellular (single-celled) grow bigger. Multi-cellular organisms increase their number of cells to develop
