Based on the analysis of the "Bill Nye: Biodiversity" Video Worksheet, here is the complete solution with answers to all the questions:
1.
For an __________ to be healthy, it must have the right balance of plants and animals.
*
Answer: ecosystem
* *Explanation:* A healthy ecosystem requires a balanced interaction between its various components, including plants (producers), animals (consumers), and decomposers.
2.
Name four types of ecosystems that host a few miles. *(Note: The phrasing "a few miles" is likely a typo and probably means "a variety of life" or similar.)*
*
Answer: Forest, Desert, Grassland, (The fourth is not visible but could be Ocean, Wetland, Tundra, etc.)
* *Explanation:* These are major biomes or types of ecosystems, each characterized by distinct climate, flora, and fauna.
3.
Describe what Bill Nye is trying to demonstrate by releasing some of the lizards into a cage of snakes.
*
Answer: He is showing that if you take away one species, it can throw off the whole balance of the ecosystem.
* *Explanation:* This demonstrates the concept of trophic cascades and interdependence within food webs. Removing a predator (snakes) or prey (lizards) can have unforeseen consequences for the entire system.
4.
Biodiversity means different __________.
*
Answer: species
* *Explanation:* While biodiversity encompasses genetic, species, and ecosystem diversity, the term most commonly refers to the variety of different species in a given area.
5.
Name the species that could be affected if the bees were gone (give at least three).
*
Answer: Flowers, Animals that eat flowers, Humans
* *Explanation:* Bees are vital pollinators. Their disappearance would lead to the decline of many flowering plants, which would then impact herbivores that rely on those plants for food, and ultimately affect humans who depend on these plants for food, medicine, and other resources.
6.
The fastest way to wipe out a species is to __________.
*
Answer: destroy its habitat
* *Explanation:* Habitat destruction, through activities like deforestation, urbanization, or pollution, removes the essential resources (food, water, shelter) a species needs to survive, leading directly to population decline and extinction.
7.
The largest ecosystem is the word a __________ where 2/3 of all species live.
*
Answer: ocean
* *Explanation:* The ocean covers more than 70% of the Earth's surface and contains a vast array of habitats, from shallow coastal zones to deep-sea trenches, supporting an incredible diversity of life.
8.
List four things you can do to increase biodiversity.
*
Answer:
* Plant native trees and shrubs in your yard.
* Avoid using pesticides and herbicides.
* Support conservation organizations.
* Reduce, reuse, and recycle to minimize pollution and habitat loss.
* *Explanation:* These actions help create healthier habitats, reduce threats to wildlife, and support efforts to protect endangered species and their environments.
