S7L4: Unit 1 Study Guide ANSWER KEY
1. An ecosystem is best described as an interaction of biotic and abiotic factors
in a given area.
2. What type of relationship is a flower and a bee? mutualism
3. A relationship in which one organism benefits and the other organism
neither benefits nor is harmed is known as commensalism.
4. Athlete’s foot is best described as a parasitism relationship.
5. True or false: Competition only occurs between organisms of the same
species. It can also occur between organisms of different species
6. Create a food chain from the following desert organisms: (1) western
diamond back rattle snake, (2) prickly pear cactus, (3) red-tailed hawk, (4)
wood rat (2), (4), (1), (3)
7. A food web and food chain differ in that a food chain consists of one path of
energy flow through a system. A food web consists of many different paths
of energy through a system.
8. Plants move energy through ecosystems because they change sunlight into
food for other animals.
9. Plants are autotrophs, they make their own food using the sun. Animals are
heterotrophs, they must consume other organisms for energy.
10.The arrow in the following scenario means energy in the plants that is being
transferred to the rabbit plant  rabbit
11.Predators depend on prey for their food. Therefore, if the prey disappears
this can affect the predators.
