Question

what natural selection pressures can lead to extinction? (select all)
a. human - induced changes in an ecosystem
b. shifts in habitats
c. changes in climate or geological events
d. species interactions with other species
why are conservation efforts considered urgent?
a. they complicate human activities
b. they help prevent extinction and maintain biodiversity
c. they are unnecessary
d. they are only needed for popular species
what is the primary goal of conservation?
a. promote habitat destruction
b. preserve biodiversity and preventing extinction
c. maximize economic gains
d. increase human population growth

Explanation:

1. Human - induced changes, habitat shifts, climate/geological changes, and species - species interactions can all create natural selection pressures that may be too great for a species to adapt to, leading to extinction.
2. Conservation efforts are urgent because they help prevent species from going extinct and maintain the variety of life (biodiversity) on Earth.
3. The primary goal of conservation is to protect the variety of life and stop species from becoming extinct.

Answer:

1. a. Human - induced changes in an ecosystem, b. Shifts in habitats, c. Changes in climate or geological events, d. Species interactions with other species
2. b. They help prevent extinction and maintain biodiversity
3. b. Preserve biodiversity and preventing extinction
