Fungus from soil
various pathogens
6Viruses only harm cells by invading them and
using the cell to reproduce
7Living organisms must fit all of the following
criteria 1. They must have organization. 2.
They must have metabolism. 3. They must respond
to the environment. 4. They must be able to
reproduce themselves.

14What do bacteria do?from a human perspective
- Good
- Decay dead material
- Help digest food
- Protect body from bad bacteria
- Nitrogen fixation
- Produce oxygen
- Bad
- Cause disease
- Food poisoning
- STDs
- Cavities
- Infections of skin or body
- Spoil food/infect crops
15CB 54.17
The nitrogen cycle
16Nitrogen as part of amino acids and nucleotides
17What do bacteria do?from a human perspective
- Good
- Decay dead material
- Help digest food
- Protect body from bad bacteria
- Nitrogen fixation
- Produce oxygen
- Bad
- Cause disease
- Food poisoning
- STDs
- Cavities
- Infections of skin or body
- Spoil food/infect crops
- 40 of planted food does not make it to table

- Specific
- B-cells -gt antibodies
- T-cells

openings) Traps particles, swallowed Stomach
acid kills pathogens
