Which of the following is not a step in the process of natural selection
Paraphin [41]

Answer:

A step that is not part of natural selection is people select which individuals breed and which ones do not.

Explanation:

Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.

As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that <u>people cannot determine which individuals breed</u>.

Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.

<em>The other options do form part of natural selection, since they are based on the three premises of this process: </em>

  • <em>Inheritable characteristics. </em>
  • <em>Genetic variability. </em>
  • <em>The variability of characteristics influences reproduction and survival.</em>

Select all of the following statements that represent examples of predation. Check All That Apply Deer eat the leaves of a tree.
Fantom [35]

Answer:

A snail eats a clam.

Explanation:

Interactions always occur between organisms in an ecosystem. An interaction between two organisms is called SYMBIOSIS. Symbiosis consists other types which includes PREDATION. Predation is a kind of symbiotic relationship between two organisms in which one kills and feeds on the other in order to obtain energy. The organism that kills is called the PREDATOR while the organism that is killed is called PREY.

In this example, a snail feeding on a clam best represents the example because the snail (PREDATOR) is obtaining energy by killing the clam (PREY). In other options, no organism is killed.
