Comparing and Contrasting
As you read, compare and contrast the two types of algal blooms in a table like the one below.
Algal Blooms
Properties
Saltwater Blooms
Freshwater Blooms
Causes
Increase in nutrients or temperature
Nutrients build up, causing a rapid increase in algae growth.

Toxins concentrated in fish and shellfish that eat algae can cause illness to people and other large organisms when they consume the fish or shellfish.
Fish and other organisms in the water die.

17. Algal Blooms 1. Sentences that are true about saltwater algal blooms.
Saltwater Blooms Pg. 199
1. Sentences that are true about saltwater algal blooms.
Saltwater algal blooms are commonly called red tides.
Dinoflagellates and diatoms are two kinds of algae that often cause red tides.
2. List two conditions that often cause red tides to occur.
An increase of nutrients in the water
An increase in ocean temperature

18. Algal Blooms
3. Why are red tides dangerous to people and other organisms?
The algae produces toxins that become concentrated in the fish and shellfish that eat the algae. When people or other organisms eat the fish and shellfish, they can become seriously ill or even die.
Freshwater Blooms Pg. 200
In a process called _________nutrients, such as nitrogen and phosphorus, build up in a lake or pond over time, causing an increase in the growth of algae.
eutrophication

19. Algal Blooms 5. Flowchart:

Question
Answer
What are fungi?
Fungi are eukaryotes that have cell walls, are heterotrophs that feed by absorbing their food, and use spores to reproduce.

23. Fungi
The cells of fungi are arranged in branching, threadlike tubes called _____.
hyphae

Starting from the top:
Cap
Gills
Stalk

24. Fungi Describe the process by which a fungus feeds.
Hyphae from the fungus grow into a food source. Digestive chemicals ooze from the hyphae into the food. The digestive chemicals break down the food so the hyphae can absorb it.
7. Some fungi are parasites.
True

25. - Fungi
What Are Fungi?
Fungi absorb food through hyphae that grow into the food source.

26. Fungi Most fungi reproduce by making _____. spores

28. Fungi Some molds produce______, substances that kill bacteria.
antibiotics
How do some fungi help plants grow larger and healthier?
The fungi’s hyphae grow among the plant’s roots and absorb water and nutrients from the soil for the plant.

29. Fungi

Fungi and Trees
A biologist conducted an experiment to see how root-associated fungi affect the growth of four different tree species. Each species was divided into two groups–trees grown with root-associated fungi and trees grown without the fungi.

32. Fungi and Trees - Fungi Reading Graphs:
How did the biologist measure tree growth?
By measuring average height in meters

33. Fungi and Trees - Fungi Interpreting Data:
For each species, which group of trees showed more growth?
Those grown with root-associated fungi.

34. Fungi and Trees - Fungi Calculating:
What is the average height difference between sour orange trees that grew with root-associated fungi and those that grew without fungi?
About 5 meters

35. Fungi and Trees - Fungi Calculating:
What is the height difference between avocado trees that grew with and without the fungi?
About 1.5 meters

36. Fungi and Trees - Fungi Drawing Conclusions:
Based on this experiment, how do root-associated fungi affect tree growth?
Root-associated fungi improve or enhance tree growth.

37. Graphic Organizer Excess nutrients flow into a lake.
Algal growth increases.
Layer of algae prevents sunlight from reaching plants and other algae beneath. These plants and algae die.
Decomposers increase in number and use up oxygen in the water.
Fish and other organisms in the water die.
