Answer:

The correct answer is: A. Only the best-adapted animals in a population survive.

Explanation:

  • Natural Selection is the process by which the individuals of a species which has the potential to sustain and survive in adverse or changing environment gets a survival advantage over those individuals which are unable to adapt themselves to altered environmental conditions.
  • As the less potent individuals die in altered environmental conditions the  adaptable individuals escapes competition with them for natural resources.
  • Evolution causes species to alter their characteristics depending upon the demand of the conditions. These changes can vary, can be less or drastic.
  • Animals pass all the newly adapted traits to the successive generations either as genetic traits or as acquired traits, as this is necessary for the offspring to survive in the altered environment.
  • Natural selection is best defined as "the survival of the fittest".

Andrej [43]

Answer:

b. True

Explanation:

Behavioral ecology is a science that studies animal behavior, considering its evolutionary and ecological bases, in which through experiments it seeks ways to show the evolutionary / adaptive causes of behaviors. Ecoetology deals with functional questions about behavior, how a behavioral pattern contributes to the survival chances of an animal or group of animals and their reproductive success. In addition, behavioral ecology is a meeting point for the study of behavior, ecology and evolution, in which ecology is the stage on which the animal must perform its behavior, and evolution in which organisms will be selected for having higher behaviors. success.

For this reason, we can conclude that the study of behavioral evolution, emphasizing the role of ecological factors as agents of natural selection, is known as behavioral ecology.

timofeeve [1]

The correct answer is: B) As land plants became more complex, animal life did as well.

This is because land could not be colonized by other organisms such as animals until land plants became established-there was nothing for animals to feed on.

So, plants were one of the earliest organisms to leave the water and colonize land.

Lemur [1.5K]

The deer eats grass, the percentage of energy will the deer acquire from the grass will be dependent on the food chain then the accurate solution is 10 percent.

  1. In a food chain, the simplest 10 percent of the strength is transferred from one trophic stage to another.
  2. The grass is the manufacturer and the deer is the number one consumer, so, whilst the deer eats the grass, it acquires 10 percent of the entire strength of the grass. Rest strength is dissipated withinside the surroundings thru the metabolic tactics taking location withinside the grass.

<h3>What is the position of deer in the food chain?</h3>

The 2nd trophic stage includes organisms that consume the producers. These are known as number one purchasers or herbivores. Deer, turtles, and plenty of varieties of birds are herbivores. Secondary purchasers consume the herbivore.

Thus it is clear that 10 percent of energy will the deer acquire from the grass.
