EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A low-level species in a food web suddenly becomes extinct. Of its predators, which will most likely survive?
A
the predators that are genetically similar
B
the predators that feed on many different organisms
C
the predators that primarily feed on the now-extinct species
D
None of the above
Explanation: 

Detailed explanation-1: -Summary: New research that analyzed more than 270 million years of data on animals shows that mammals and birds–both warm-blooded animals–may have a better chance of evolving and adapting to the Earth’s rapidly changing climate than their cold-blooded peers, reptiles and amphibians.

Detailed explanation-2: -According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Detailed explanation-3: -Camouflage allows organisms to become almost invisible to predators. Some species have evolved morphological adaptations that allow them to blend in with their environments.

Detailed explanation-4: -Selection: Survival and Reproduction Because resources are limited, more organisms are born than can survive: some individuals will be more successful at finding food, mating or avoiding predators and will have a better chance to thrive, reproduce, and pass on, their DNA.
