Objectives
State Performance Indicators:
SPI 0807.5.2 - Analyze structural, behavioral, and physiological
adaptations to predict which populations are likely to survive in a
particular environment
SPI 0807.5.3 - Analyze data on levels of variation within a
population to make predictions about survival under particular
environmental conditions.
SPI 0807.5.4- Analyze data on levels of variation within a
population to make predictions about survival under particular
environmental conditions.
Study Guide
1. Define Classification. The division of
organisms into groups, or classes, based on
specific characteristics.
2. What are the eight levels of classification?
Domain, Kingdom, Phylum, Class, Order,
Family, Genus, Species
3. Scientists classify organisms by? A two part
scientific name that consists of the genus &
species.
4. Be able to use a branching diagram.
5. What is a dichotomous key? An aid that is used
to identify organisms and that consist of the
answers to a series of questions.
Study Guide
6. Define adaptation. Characteristics
that improve an individual’s ability to
survive and reproduce in a particular
environment.
7. What are the 3 kinds of adaptations?
1. Obtaining Food 2. Predator-Prey 3.
Interactions (Symbiosis)
8. Define Natural selection. The process
by which individuals that are better
adapted to their environment survive
and reproduce more successfully than
less well adapted individuals do.
9. Name and describe the four steps of natural
selection.
1. Overproduction - more offspring are born
than will live to become adults.
2. Genetic Variation - Individuals in a population
differ from one another. Some characteristics
improve chances while others lower chances
for survival.
3. Struggle to Survive - Many individuals die
from lack of resources. Others are killed by
predators or cannot find mates to reproduce.
The ones who find resources survive!
4. Successful Reproduction - This is the key to
natural selection. The strong survive, while the
weak die early or have few strong offspring.
10. What is genetic variation? Differences among
organisms that are passed on from parent to
offspring that help them survive better.
11. What is genetic bottlenecking? When a
population decreases rapidly, the
characteristics of the individuals are reduced
causing problems like birth defects.
12. What are the 3 types of evidence that show an
adaptation? Physical adaptations, Behavioral
adaptations & Physiological adaptations
13. Define Species. A group of organisms that
can mate with one another to produce fertile
offspring.
14. Define population. Groups of individuals of
the same species living in the same place at
the same time.
