Question

natural selection: the process
complete this word - fill to summarize the process of natural selection
individuals in a population show
______ due to random
______ and meiosis (in
species that reproduce
______). there
is
______ between individuals for
access to resources, e.g. food and
______
the individuals that are best
______ to
their
______ are more likely to
survive and
______, passing on their
beneficial
______ to their offspring. those
that do not have beneficial traits are likely
to
______ before they can reproduce, so they
do not
______ on their traits.
this process is called natural
______, and is sometimes referred to
as survival of the
______. over time, the population evolves.

Explanation:

Individuals in a population show variation due to random mutations and meiosis (in species that reproduce sexually). There is competition between individuals for access to resources, e.g. food and mates. The individuals that are best adapted to their environment are more likely to survive and reproduce, passing on their beneficial traits to their offspring. Those that do not have beneficial traits are likely to die before they can reproduce, so they do not pass on their traits. This process is called natural selection, and is sometimes referred to as survival of the fittest.

6. adapted
7. environment
8. reproduce
