Why does deforestation lead to a loss of bioprospecting potential?
a) Deforestation encouraging the discovery of new species.
b) Deforestation destroying habitats where potential medicinal plants and genetic resources exist.
c) Deforestation enhances the growth of diverse plant life.
d) Deforestation allows easier access to biological resources.
b) Deforestation destroying habitats where potential medicinal plants and genetic resources exist
How does forest fragmentation contribute to the loss of endemic species?
a) Isolated patches leading to genetic diversity.
b) Isolated patches reduce genetic diversity.
c) Isolated patches increasing a new variety of species in that fragmented habitat.
d) Isolated patches hindering variation and reproductive isolation.
b) Isolated patches reduce genetic diversity.
Why does agricultural expansion lead to deforestation?
a) Agricultural expansion improving forest ecosystem health.
b) Agricultural expansion requires large areas of cleared land for crops and livestock.
c) Agricultural expansion creating new forest habitats.
d) Agricultural expansion enhancing forest species diversity.
b) Agricultural expansion requiring large areas of cleared land for crops and livestock
How does the “non-implementation of policies and corruption of former government” contribute to deforestation?
a) Policy loopholes facilitating selective afforestation projects that further fragment forests.
b) Policy negligence enabling unchecked illegal logging and land conversion, resulting in habitat destruction.
c) Policy ambiguities leading to the proliferation of invasive species that outcompete native flora.
d) Policy misinterpretations causing the strategic abandonment of conservation zones, increasing vulnerability to deforestation.
b) Policy negligence enabling unchecked illegal logging and land conversion, resulting in habitat destruction.
Why does deforestation lead to a disruption of food chains?
a) Deforestation promoting trophic complexity through the introduction of novel predator-prey dynamics.
b) Deforestation eliminating habitats and food sources, destabilizing trophic interactions and causing ecosystem collapse.
c) Deforestation fostering ecological resilience by enhancing species dispersal and niche diversification.
d) Deforestation triggers a cascade of compensatory mechanisms that maintain ecosystem stability despite habitat loss.
b) Deforestation eliminating habitats and food sources, destabilizing trophic interactions and causing ecosystem collapse
