Define biodiversity and the importance of diversity in ecosystems. How could humans harm an ecosystem's biodiversity?
Answers
Answer:
Biological diversity - or biodiversity - is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans.
Explanation:
Biodiversity is important to humans for many reasons. ... Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species.

Artificial selection is based upon humans making the choice about which traits are favored and which parents will be allowed to reproduce. Natural selection is based upon factors in the natural environment favoring certain parents to produce offspring
Answers
Answer: True
Explanation:
The artificial selection allows humans to exploit the genetic resources (alleles, genes) of the organisms during mating. This allows the transmission of valuable and desirable traits of both parents to the offspring. This improves the quality of milk, meat, and plant yield. Natural selection is a natural phenomenon human have no role in natural selection. In this the nature selects those individuals to survive in their environment which have better phenotypic traits over others. These traits allows the organism to survive and reproduce and the beneficial traits are passed on to the next generation. On contrary, the traits which are beneficial in one kind of environment can be harmful in other environment. For example, the bears have thick coat which allows them to survive in cold conditions but in extreme heat they may not survive.
