1. the availability of food, water, shelter and space.
2. Common limiting factor resources are environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem. The limiting factor also causes competition between individuals of a species population.
Example: Space, food, or water.
3. Limiting factors, such as food, would sometimes cause one organism to kill another to survive or fight over that factor. But with space, it would get crowded probably.
4. ( i couldn't find anything about South America Ecosystems Interactive... sorry )
5. "Native people" are ethnic groups who are the original inhabitants or descendants of the original people.
Example: the Yanomami and the Tupi People of the Amazon.
6. I would say do an experiment or something???
7. A variable is any factor, trait, or condition that can exist in differing amounts or types.
8. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation. The dependent variable is also called the outcome variable.
9. A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.
Example: when testing for a new pill, one group is given the pill to see affects, one group (the control group) is given a placebo and is used to see what happens when given a placebo.
10. Changes in limiting factors will cause a population to decrease.
11. They are transmitted from indirect contact usually.
12. An animal or plant on or in which a parasite or commensal organism lives.
Example: When a human doesn't wash his/her hands and that makes someone else sick. Another one is since humans naturally have bacteria, some are bad and can cause a virus.
13. An infectious agent is something that infiltrates another living thing.
14. Lack of membrane-bound organelles, unicellular, and small.
15. cocci, bacilli, and spirilla.
16. Viruses can replicate only by infecting a host cell and they cannot reproduce on their own.
17. Influenza, HPV, and rabies.
18. Any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter.
Example: Pink waxcap, coral tooth, and pig's ear. (this is not their scientific name haha)
