Answer:
Cheetahs are a very resilient population and unlikely to become extinct.
Explanation:
LH Gunderson (2000) Defined ecological resilience as "the amount of disturbance that an ecosystem could withstand without changing self-organized processes and structures."
When a population is resilient, it tends to bounce back after major perturbations.
For instance, the Cheetah population was at the brink of extinction around 10,000 years ago, and then also again around 100 years ago yet the population was able to recover at both periods and never went extinct.
This implies that Cheetahs are a very resilient population and unlikely to become extinct.
Answer:
The correct answer will be option-B.
Explanation:
Photosystem of a plant is complex pigment-protein molecules which absorbs the light energy required for the formation of a glucose molecule.
Two types of Photosystem are present in the plants which are: P₆₈₀ and P₇₀₀. The 680 and 700 denote the wavelength of the light energy absorbed by the pigment of the chloroplast. The electrons get excited only at their absorbing wavelength.
Thus, Option-B is the correct answer.
