Chapter 1 Test Review
Chapter 1, Section 1: Everything Is Connected (Textbook Pages 4-7)
1. What does biotic mean? List 2 examples.
2. What does abiotic mean? List 2 examples.
Biotic means (living/nonliving).
Abiotic means (living/nonliving).
Examples:
1) Tree
2) Animal
Examples:
1) Temperature
2) Sunlight
3. Put the levels of environmental organization in order from smallest to largest: (community, ecosystem, biosphere, organism, population).
_______organism________
(smallest)
_____popluation_____
______community______
_____ecosystem______
______biosphere_______
(largest)
4. What is a population?
5. Give an example of a population.
6. What is a community?
A population is a group of organisms
that live in the same place.
An example of a population is a school
of fish living in the same ocean.
A community is all of the populations
of organisms that live and interact
in a specific area.
7. Give an example of a community
8. What is an ecosystem?
9. Give an example of an ecosystem.
An example of a community is a
Jaguars and Emerald Tree Boas
living and interacting in a place.
An ecosystem is a community and all
of the abiotic factors in that environment.
An example of an ecosystem is all of the
plants, animals, sunlight, and other
abiotic features of the environment.
Chapter 1, Section 2: Living Things Need Energy (Textbook Pages 8-13)
10. List what the following organisms eat: herbivore, carnivore, omnivore.
a) An herbivore eats: plants
b) A carnivore eats: meat
c) An omnivore eats plants and meat.
11. What is a producer?
A producer is an organism that
gets energy from the sun.
12. List an example of a producer.
An example of a producer is a plant.
14. List an example of a consumer .
An example of a consumer is a deer.
15. What is a decomposer?
A decomposer is an organism that
gets energy from breaking down dead
organisms.
13. What is a consumer?
A consumer is an organism that gets energy from
eating other organisms.
16. List an example of a decomposer.
An example of a decomposer is fungi or bacteria.
17. What is a food chain designed to show?
A food chain is designed to show how
energy is transferred in an ecosystem.
18. What does a food web show?
A food web shows the feeding relationships between organisms.
19. What does an energy pyramid show?
An energy pyramid shows an ecosystem’s loss
of energy as energy passes through the ecosystem’s
food chain.
20. Where is the most energy found in an energy pyramid: top or bottom?
The most energy is an energy pyramid is found at the bottom of the energy
pyramid.
Chapter 1, Section 3: Types of Interactions (Textbook Pages 14-21)
21. What is a limiting factor?
A limiting factor is a resource that is so scarce
that it limits the size of a population.
22. What does the term “carrying capacity” mean?
Carrying capacity means the largest population that an environment can support
at any given time.
23. What are the four types of interactions between organisms discussed in Chapter 1, Section 3?
1) Competition
2) Predator-Prey
3) Symbiosis
24. Define “competition.”
Competition is when 2 or more
organisms or populations
try to use the same resource.
4) Coevolution
25. Provide an example of competition.
An example of competition is two trees
that need to use the same sunlight to make
energy.
26. Provide an example of the predator-prey relationship.
An example of the predator-prey relationship is when a
fox hunts, kills, and eats a rabbit.
26. Define the “predator-prey” relationship.
The predator-prey relationship is when one
organism (the predator) eats another (the prey).
27. How do adaptations help predators?
Adaptations help predators to catch and eat their pre y.
28. How do adaptations help prey and what are 3 examples of prey adaptations?
Adaptations help prey to avoid/escape being eaten.
Examples:
1) Camouflage
2) Warning Coloration
3) Chemical Defenses
28. Define “symbiosis.”
Symbiosis is a close interaction
between two organisms of different
species over a long period of time.
31. Define “commensalism.”
Commensalism is when one organism
benefits and the other is unaffected (+/0)
33. Define “parasitism.”
Parasitism is when one organism
benefits and the other is harmed.
29. Define “mutualism.”
Mutualism means both organisms
get a benefit. (+/+)
30. Provide an example of mutualism.
An example of mutualism is a bee pollinating
a flower.
32. Provide an example of commensalism.
An example of commensalism ism is the cattle egrets (birds) and livestock. (See notes)
34. Provide an example of parasitism.
An example of parasitism is a flea on
a dog.
35. What does “coevolution” mean?
Coevolution is the long-term change that takes
place in two species because of their long-term
interaction with one another.
Diagrams:
a) Be able to describe how a food pyramid works and how to determine where the most and least energy in the pyramid are.
b) Be able to distinguish who eats whom and how energy is transferred from one organism to the next by looking at a food web.
Constructed Response:
-Describe a type of symbiosis (mutualism, commensalism, or parasitism)
-Provide an example of the type of symbiosis you chose.
-State whether is organism in the interaction benefits (+), is harmed (-), or is unaffected (0).
