X: commensalism  Y: mutualism  Z: parasitism

Question 3

3.

Increased production of acid rain will poison some aquatic ecosystems.

Decreased energy to drive atmospheric water cycles will result in more predictable weather patterns.

Question 5

5.

Rainfall raised temperatures above survivable levels for mosquitoes.

Flooding increased predation and disrupted ideal breeding habitats.

Excess water diluted the mosquito larvae and made reproduction impossible.

Question 6

6.

All non-native species eventually become extinct

Some non-native species provide no ecological function

Question 7

7.

Question 8

8.

Species A is a keystone species in this ecosystem.

The two populations have similar sets of limiting factors.

125 kcal

12,500 kcal

Question 10

10.

Mold will grow less in cold temperatures

What temperature is best for growing mold on a loaf of bread?

Question 11

11.

Bird species change over time

The effect of protection on the population of bird species

Question 12

12.

As the number of leaves removed increases, the transpiration rate decreases

As the number of leaves removed increases, the transpiration rate increases

Transpiration rate increases when there are more leaves removed

Question 13

13.

The organism must have an arrow pointing to it from a producer and another arrow  pointing to it from a primary consumer.

The organism must have an arrow pointing from it to a primary consumer and another  arrow pointing away from it to a decomposer

The organism must have an arrow pointing from it to a secondary consumer and  another arrow pointing to it from the top predator.

Mice, rabbits, herbivorous insects, and  squirrels

Predaceous insects, toads, spiders, and  foxes

Question 23

23.

DNA

Sugar

Fats

Question 24

24.

Snails

Protozoa

Question 25

25.

Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas.

Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean.

Less atmospheric carbon dioxide would be available to phytoplankton.

Question 26

26.

Relationship 1 is an example of commensalism.
Relationships 2 and 4 are examples of mutualism.
Relationship 3 is an example of predation.

Relationships 1 and 4 are examples of mutualism.
Relationship 2 is an example of commensalism.
Relationship 3 is an example of parasitism.

Relationships 1 and 2 are examples of commensalism.
Relationships 3 and 4 are examples of mutualism.

Question 27

27.

Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.

Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.

Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.

Question 28

28.

Carbon dioxide (CO₂)

Oxygen (O₂)

Methane (CH₄)

Question 29

29.

It decreases

It increases 

It stays the same

Question 30

30.

Increased carbon dioxide (CO₂) absorption by seawater

Increased salt in the ocean

Question 31

31.

An increase in salinity results in an increase in biodiversity

There is no relationship

A decrease in salinity results in a decrease in biodiversity

A decrease in salinity results in an increase in biodiversity

Question 32

32.

There is no correlation between sea surface temperatures and coral bleaching events.

Coral bleaching events are more frequent when sea surface temperatures decrease.

Wetlands forming from a receding glacier.

A forest regrowing after a fire.

Question 40

40.

Slower rabbits will develop stronger legs and pass this trait to their offspring.

The rabbits will mutate their genes and express genes that increase their speed.

Question 41

41.

More sugars and starches would be available for animals in the area.
