Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement best describes why traits that allow organisms to adapt to changes in their environments are considered to be beneficial?
A
These traits make it more difficult for the organisms to find mates.
B
Organisms with these traits are more likely to survive and reproduce
C
These traits make it easier for predators to find and eat the organisms
D
Organisms with these traits have shorter lifespans so they do not compete with their offspring
Explanation: 

Detailed explanation-1: -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-2: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-3: -All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.

Detailed explanation-4: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-5: -The theory of evolution by natural selection means that the inherited traits of a population change over time. Inherited traits are features that are passed from one generation to the next. Natural selection explains how organisms in a population develop traits that allow them to survive and reproduce.
