You will learn what elements make up the human body, and how scientists use and develop models. After a brief history of biology, discover the major types of molecules made of these elements.
After completing this tutorial, you will be able to complete the following:
Why did Einstein believe that the extinction of bees would lead to the end of human life on Earth?
~ Einstein believed that human life on Earth might cease to be if bees became extinct because he understood that bees play a vital role in sustaining our ecosystem. Einstein knew that because bees are very important to the pollination of plants, the extinction of bees would reduce the number of plants and the number of animals that depend on these plants for food. Eventually, this problem would lead to the extinction of humans.
What is biodiversity?
~ Biodiversity refers to the variability among the species within a particular habitat.
Describe how biodiversity contributes to the sustainability of a forest ecosystem.
~ Biodiversity contributes to the sustainability of ecosystems. Biodiversity offers greater diversity of pathways for matter and energy flow, thus buffering the system against changes should one or a few species vanish. Also, biodiversity within species provides genetic variation that can allow species to adapt to changes in the environment, or possibly survive catastrophes, which increases the sustainability of the ecosystem as a whole. For example, biodiversity within a population of pine trees might allow some of them to survive an outbreak of bark beetles. The surviving trees could thus repopulate the forest. Without this biodiversity, the tree population might be wiped out, which would also destroy all the other species that depend on them, since trees are on the first trophic level.
How is biodiversity important to our everyday lives?
~ Biodiversity plays a very important role in our daily lives, as we depend on many different plant and animal species to survive. Many of these species provide us with food, oxygen, medicine, and other products we need.
