Answer:

The correct choice is A)

There will be fewer producers in the area.

Explanation:

Very easy to deduce. A producer in biology of ecosystems is an organism that produces its own food. Another word for a producer in biology is 'autotroph'.

They produce energy directly from the energy given off by the sun or chemicals or both.

Grass (or plants) are producers. They do this with the help of water, converting solar energy into sugar or food, which are usable forms of energy.

So the more grass is consumed, the fewer producers in the area.

Cheers!

Natural Selection: Mastery Test
Finger [1]

Answer:

Genetic diversity in a small population, with a high level of genetic drift and with very little migration will decrease because existing alleles will be lost and few new alleles will be introduced over time (option A).

Explanation:

Evolution - linked to the natural selection and perpetuation of a species - depends, in large part, on three fundamental factors to make it happen:

  • Mutations .
  • Genetic drifts.
  • Migrations.

In small and isolated populations, very little genetic variation, high levels of genetic drift and very few mutations can be observed, which could lead to some alleles being lost and the species may become extinct.

Genetic drift (GD) is an important factor in terms of natural selection, as it is the result of allelic variations that occur from one generation to another. In large populations, GD is low, given the cross between different individuals is greater. A characteristic of GD in small populations is that their levels are very high, and this leads to the eventual loss of alleles.

In this small population, without the possibility of migration -few new alelles will be introduced- genetic variation will decrease, due the genetic flow is low, reducing reproductive fitness and weakening the population's resistance to environmental changes, which could result in the long-term extinction of the species.
