1. For a(n) ecosystem to be healthy, it has to have lots of different kinds of plants and animals. 2. Name four types of ecosystems from those listed in the video. A. B. C. D. 3. Describe what Bill Nye was trying to demonstrate by removing some of the blocks in his tower of blocks. 4. All living things depend on _________________. 5. Name at least two species that have gone extinct. (four were shown) 6. The best way to wipe out a species is to _. 7. The largest ecosystem in the world is , where 2/3 of all species live. 8. List five things you can do to increase biodiversity. A. B. C. D. E. 9. Of the 30,000,000 species on Earth, how many are lost each HOUR? 10. In conclusion, Bill Nye states that "As more and more species disappear, it's harder and harder to keep an ecosystem in balance because we don't know WHAT?

All living things depend on their environment that supply food, shelter and water that is necessary for their survival. Sabre-toothed Cat and Woolly Mammoth are the two species that have gone extinct due to unfavourable environmental condition. The best way to wipe out a species is to remove food and water resources. The largest ecosystem in the world is World Ocean where two third of all species live. Of the 30,000,000 species on Earth, three species are lost each hour. In conclusion, Bill Nye states that "As more and more species disappear, it's harder and harder to keep an ecosystem in balance because every specie in the ecosystem balances other specie.

1. The ecosystem is defined as the relation of plants and animals, which depend on each other and work efficiently with the surrounding. For an ecosystem to be healthy, the diversity of the organisms are necessary and proper availability of resources.

2. The four types of the ecosystem are terrestrial, artificial, lentic, and lotic. Terrestrial refers to the ecosystem on land, artificial ecosystems can be human-made, lentic and lotic are the types of aquatic ecosystems.

3. In the video, Bill Nye was trying to demonstrate that everything depends on its building block and resources.

4. The biotic components of the ecosystem depend on food, shelter, and water.

5. Extinction refers to the complete elimination of an organism due to natural or human-made factors. Examples of extinct animals are the Wolly mammoth and Dinosaurs.

6. The best way to wipe out species is the change of ecosystem or the habitat in which the organism is thriving.

7. The largest ecosystem in the world is the ocean, where the majority of the species are found and some of them are yet to explore.

8. The biodiversity can be increased by increasing vegetation, diversifying the resources, making shelters available, and plenty of water.

9. Each hour approximately 3 species are lost. It can be due to natural calamity or human factors.

10. The preservation of the ecosystem is necessary, and the soon endangering of the species will lead to unbalance of the ecosystem, as species depend on each other.
