How can we protect the earth Biodiversity

Question 1

Types of Biodiversity

Answer 1

-chemical
-ecosystem
-species

Question 2

chemical diversity

Answer 2

a way to measure diversity of human health and welfare

Question 3

ecosystem diversity

Answer 3

the number of different ecosystems on earth or in a geographical area

Question 4

species diversity

Answer 4

number and variety of species in a particular region

Question 5

bioprospecting

Answer 5

-The process of discovering commercialization of indigenous knowledge of biological resources

-White people stealing and profiting off of indigenous people remedies without giving credit

Question 6

2 hypotheses explaining why biodiversity decreases toward the poles:

Answer 6

1.The greater age of the ecosystem in the tropics provide more time for speciation

2.The greater energy the tropics receive from the sun vs. the lesser energy input in temperate and polar regions

*Sunlight is the key to plants and there is more near the equator meaning there is more animals
*more species closer to the equator

Question 7

Threats to Biodiversity

Answer 7

-Habitat loss
-Overharvesting
-Exotic/Invasive Species
-Climate Change

Question 8

Habitat Loss

Answer 8

species no longer have a habitat available, and has adapted to be living in there (it can’t survive)

-Habitat fragmentation- habitats can be fragmented into patches that are too small to support species
-Habitat degradation: habitats can be degraded by pollution to the extent that they are no longer livable

Question 9

Overharvesting

Answer 9

Not the same as hunting…ex;fish

Question 10

exotic/invasive species

Answer 10

when species evolve alongside one another…They’re adaptations allow them to deal with the others presence

Question 11

climate change

Answer 11

a drastic form of habitat degradation or loss (ex; polar bears and the loss of sea ice due to melting)

Question 12

Ways to Protect Biodiversity

Answer 12

-Conscious decision making: consumer choices, follow hunting regulations, reduce carbon footprint

-Support conservation in preserves: ex; visiting a state or national park in the U.S, your supporting conservation and preserves because your entrance fee goes toward its protection

-Support habitat restoration: reintroduce once endangered species into their native habitat…protect the habitat so its available for the species to be reintroduced to it

Support zoos/aquaria: zoos and aquariums have captive breeding programs…the breeding programs allow scientist to increase population numbers of endangered species
