biodiversity and biodiversity loss Flashcards

Q

is defined as the variety of different species (species diversity),
genetic variability among individuals within each species (genetic diversity), variety
of ecosystems (ecological diversity), and functions such as energy flow and matter
cycling needed for the survival of species and biological communities (functional
diversity).

These wild species are still relatively abundant in
their natural range but are likely to become endangered in the near future if
current trends continue, such as declines in population or habitat destruction.

20
Q

advantage of GMO

A

Need less fertilizer

Need less water

More resistant to insects, plant
disease, frost, and drought

Faster growth

Tolerate higher levels of herbicide
use

Higher yields

21
Q

disadvantages of GMO

A

Irreversible and unpredictable genetic
and ecological effects

Harmful toxins in food from possible
plant cell mutations

New allergens in food

Lower nutrition

Increased evolution of
pesticide-resistant insects and plant
diseases

Creation of herbicide-resistant weeds

Harm beneficial insects

Lower genetic diversity
