b) i) the total number of alleles in one population

ii) low genetic gene pool are more susceptible to the same envirement pressure which can lead to extinction

c) The consequences of the decline of the Espanol tortoise population is that it will distrupt the natural food web in the envirement. The predator that feeds on the Espanol tortoise will slowly shrink in population and go extinct

🐢

b) i. set of genes in a population or species

ii. vunerable to changes, which would lead to extinction

c) overpopulation of plants

B)i) sum of all the alleles of all individual in espanola tortoise population

ii) low genetic variability in the gene pool reduces the ability of a population to adapt to environmental changes

c) imbalance in ecosystem that could affect other species like(foods)

b)

i) Complete set of all the different genes and their variations present in a population of a species.

ii) Since low genetic variability results in low gene pool, there is only a little trait and allele could be inherit by the tortoise. This decreases the chances of the tortoise to inherit defensive or resistance trait which leads to extinction.

C) If the number of Galapagos tortoises decreases, the island’s ecosystem will be affected. Tortoises help spread seeds and keep vegetation balanced by eating plants. With fewer tortoises, some plants may not grow well, and this can affect other animals that depend on those plants for food and shelter.
