NEET BIOLOGY

Detailed explanation-1: -According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.

Detailed explanation-2: -Animals have limited amounts of energy they can use for reproduction. Animals with high fecundity spend their energy in the production of many offspring that do not require much care. Alternatively, animals with low fecundity produce fewer offspring, and have more energy to care for those offspring.

Detailed explanation-3: -A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.

Detailed explanation-4: -Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.

Detailed explanation-5: -In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce.
