Name:___________________________________ Hour:_____________________________ Zoology Review 1. What is the definition of ecology? ___________________________________________________________________________ ___________________________________________________________________________ 2. All areas of life science build upon something simpler and smaller. Give the order of each level of organization from smallest to largest and give an example of each level ________________________ __________________________ ________________________ __________________________ ________________________ __________________________ ________________________ __________________________ ________________________ __________________________ ________________________ __________________________ ________________________ __________________________ ________________________ __________________________ ________________________ __________________________ 3. Give an example of how the number of populations in an ecosystem depends on both the biotic and abiotic factors found in that environment. (hint: Think of a population of deer in a forest or fish in a lake) Biotic: ___________________________________________________________________________________ ___________________________________________________________________________________ Abiotic: ___________________________________________________________________________________ ___________________________________________________________________________________ 4. Describe ways that human activities can change the number of populations in an ecosystem and then explain what would happen if our actions destroyed one entire population, what effect would that have on other populations found there? _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ 5. What are the five characteristics that all living things share? ________________________________ ________________________________ ________________________________ ________________________________ ________________________________ 6. What do you call the interaction between animals when one animal benefits from their relationship and the other is not affected at all? _______________________________ 7. What do you call the nonliving parts of an organism’s environment? ____________________________ 8. What do you call an animal that eats other animals to survive? _______________________________ 9. What do you call an animal that lives off of another animal usually harming the animal it is living on? ________________________________ 10. What do you call the interaction where one organism kills and eats another organism for food? ________________________________ 11. What do you call the living parts of an organism’s environment? _________________________________ 12. What do you call Behaviors or physical characteristics that allow organisms to live successfully in their environment? __________________________________ 13. What do you call a close relationship between two species that benefits at least one of the species? _________________________________ 14. What do you call the interaction where there is a struggle between organisms to survive as they attempt to use the same limited resource? ___________________________ The 11 human body systems are as follows: (Match each system to the correct function) 15.
