Question

1. Plant productivity will increase linearly with diversity if each plant is specialized in capturing different aspects of the resources in the environment. Which pattern of evolution could cause such a pattern of complementarity to arise?

a. Niche partitioning

b. Priority effects

c. Negative frequency-dependent selection

d. Compensatory mortality

e. Neutral theory

2. Which of the following is NOT evidence for global warming?

a. Melting glaciers and ice caps

b. Global sea levels dropping

c. Shifts in range and phenology of various species

d. Direct measurement of temperature over time

e. All of these are evidence for global warming

3. True or False: All introduced species are a threat to biodiversity.

a. True

b. False

Answer 1

Ans-1)nitche partitioning

Explaination:

Niche partioning is a process in which two competitive species coexist through use of environment resources in different way which help in coexistence and increases the biodiversity.

Ans-2)b) global sea level dropping

Explaination: due to global warming global sea level rises.

Ans-3)true

Explaination: All introduced species in a new habitat flourished very fastly due to absence of natural predator and leads to decrease in native species by disturbing or changing food web of native species hence result in decreasing biodiversity .
