b.sunlight
There are two species of fish that live in the same pond. eat the same water plants and are
eaten by the same water bird.
- Determine which of the following scenarios would cause competition between the two
species of fish.
The numbers of food plants increase:NO
An increase in the population of waterbirds:NO
The water level in the pond decreases:YES
The habitat temperature increases slightly:NO
Graphical Analysis: Analyze the data tables to answer the following questions.
- What is the texture of soil in climate zone 9?
a. Sandy
- Which species of trees require the texture of soil found in climate zone 9?
a. Black Hickory
b. Chinese Elm

- Eagles and grizzly bears live together in the same habitat. There will be competition
between the eagles and the grizzly bears if which of the following is true?
c. Both grizzly bears and eagles feed on the same species of salmon
CLAIM:
The burmese pythons had a negative impact on the ecosystem.
- Organisms compete in many ways, and some factors affect competition more than
others. Which statement is the most important from the list below.
d. The Organisms require the same resources
a. Rainfall the previous spring was slightly higher than the yearly average?
b. More insects that pollinate the flowering plants move into the habitat?
c. Wolves, which prey on deer, were being hunted more than usual.?
d. Humans introduced grazing animals that feed on the same plants as the deer?
a.remain the same
b.increase
c.increase
d.decrease
- What two trees(Select two answers) would be most likely to compete in Climate Zone
9?
a.Black Hickory
f.Sweetgum
EVIDENCE:
- The amount of pythons increased in the years 99-07.
- All mammal populations decreased in the years 99-07.
REASONING:
How do you know they had a negative impact? What does the data mean? USE THE
WORD BECAUSE!!!!
The burmese pythons had a negative effect on the ecosystem. The amount of pythons
increased in the years 1991-2007. This shows that the pythons increased quickly in the
environment. All mammal populations decrease in the years 1999-2007. This shows that
the pythons were eating all of the native species. Therefore, The burmese pythons had
a negative effect on the ecosystem.
