Question

1. Forest ecosystems provide all of the following functions EXCEPT;

a. producing oxygen
b. controlling soil erosion
c. removing carbon from the atmosphere
d. lowering the biodiversity of the plant

2. Extinction is a natural process that occurs when the last member of a species does. Which of the following correctly arranges the mass extinction events from earliest to latest?

a. Cretaceous-Tertiary, Ordovician-Silurian, Late Devonian, Permian-Triassic, Triassic-Jurassic

b. Late Devonian, Cretaceous-Tertiary, Ordovician-Silurian, Permian-Triassic, Triassic-Jurassic

c. Ordovician-Silurian, Late Devonian, Permian-Triassic, Triassic-Jurassic, Cretaceous-Tertiary

d. Ordovician-Silurian, Permian-Triassic, Triassic-Jurassic, Late Devonian, Cretaceous-Tertiary

3. Which contributes the most biodiversity loss?

a. habitat destruction b. pollution
c. invasive species d. population growth

4. Extinction can be caused by a Natural Phenomenon such as storm, flash floods, or Anthropogenic (Human made). Which of the following is believed to be the major and most impactful anthropogenic cause of extinction?

a. habitat destruction b. overpopulation
c. overexploitation d. pollution

5. Which of the following is not a benefit that tress can provide?

a. They can trap sediments and runoffs that help improve water quality.
b. They prevent the excessive warming of the planet by sequestering Carbon dioxide.
c. They serve as filters that rid the air of harmful pollutants and toxic gases.
d. None of the above.

Answer 1

1. d

2.c

3.a

4.a

5.d

Step-by-step explanation:

1. Forests ecosystem have high biodiversity

3.Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.

4.It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count.

5. Im not sure.

It may be ans c. As Trees absorb toxic chemicals through their stomata, or 'pores', effectively filtering chemicals from the air.
