Directions: You have two days to complete your research and logbook. You will need to go to biomes. to access the movie and information you will need.

After you watch the movie, click on the link that will take you to the information pages. Read each page and fill in the blanks in this logbook with the answers.

Our Planet’s Biomes

_________________,________________,and _________________

4. A biome in one part of the Earth will be ___________ but not _____________ to a biome in another part of the Earth.

Many ___________________ __________________can be seen. Very quickly, summer ends, and it is back to the long, harsh, cold __________.

The Coniferous Forest (Taiga) Biome

9. This biome is made up of several different kinds of ______________ called _____________.

10. This biome enjoys ______________than the tundra regions, but it can still get very _________

11. Exploring the coniferous forest biome, you are likely to find many interesting plants and animals, including ___________, ___________, _______________, and many other types of_______________, and a variety of ___________

The Deciduous Forest Biome

12. Traveling still further _________, we find what is called the deciduous forest biome. These forests cover much of the _________________ and most of _____________.

13. The trees of a deciduous forest shed their leaves in the ________, and grow new leaves each __________.

14. This along with the _____________ and ____________ means that the soil of a deciduous forest is _________ than that of the coniferous forest biome.

15. Also, because more sunlight reaches the forest floor, the ground is covered with a variety of ____________, __________, and ___________.

Trees Top the Greenhouse Effect

16. Animals, including people, need ___________ to breathe. Without it, we cannot live. We breathe in oxygen and exhale _______________. Trees need carbon dioxide to survive and create oxygen. We each create what the other needs just by being ___________. In fact, one acre of trees takes care of six tons of carbon dioxide and produce four tons of oxygen! That’s enough clean air for _________ people to breathe for one whole ________!

17. The quality of air in places with lots of trees is much better than air quality in cities or in areas with a sparse tree population. That’s because trees and other plants filter out __________ and _________ like carbon monoxide, nitrogen dioxide and sulfur dioxide.

The Tropical Rainforest Biome

18. Moving further south, we come upon an area which scientists call the __________________ Biome. This name comes from the fact that these forests receive a very large amount of ________ each year. All of this water, along with a constant year round supply of warmth and sunlight, have helped the rainforests grow into beautiful rich gardens covered with plants, flowers, insects, _______, and _________.

19. Rainforests can be found throughout the world. The largest, known as the __________________, is found in __________________.

20. Rainforests contain a wide variety of diverse life forms. Almost ________ of all living things on Earth can be found living inside these amazing habitats. The plants and animals here have become highly specialized, depending on each other to survive. Certain species of insects have evolved specifically to care for and _____________ a specific species of plant.

The Grassland Biome

21. The grassland biomes of Earth support many different kinds of large and small _____________ animals, as well as ________________ animals who feed on them. From the large African __________, to the tiny field mouse, lions, ___________, hippopotamuses, ______________, and more.

22. In North American grasslands, you might find a herd of American __________, antelope, a variety of bird life, _____________, also known as mountain lions, ____________, and more.

The Desert Biome

23. Because deserts receive very little _________, plants and animals have become specialized to _____________ under extreme conditions. _________have evolved unique techniques of storing large amounts of water within their bodies. Likewise, ________ and other desert plants have learned that to survive they must store the water they need so that it is available during the ______ seasons.

24. The desert biomes often experience very ________ days and very _______ nights. Creatures that live here have to do well in both extreme _________and _____________ cold.

It includes five main oceans: the Pacific, Atlantic, Indian, Arctic, and Southern, as well as many smaller Gulfs and Bays. Marine regions are usually very _______! There is about one _____ of salt per gallon of water in the ocean.

26. Over ___________ species of plants and animals have been discovered in the oceans, and scientists say there may be as many as __________ species we haven't found yet.

27. The Earth's oceans are home to most of the planet’s ____________. Here we can find mollusks, fish, _______, crustaceans, ________, fungi, sea anemones and many other animals.
