I had to look for the options and here is my answer:
Based on the attached details about the cattle egrets, how an ecologist would explain this expansion is that, a habitat that has been not been occupied by the egrets and the native herons acquired the biotic and abiotic standards <span>of the cattle egret transplants and their descendants. (This is based on the actual option attached to this question.)</span>
Chemical energy: When animals eat plant, they get the chemical energy in the plants stored as sugar.Mechanical energy: Carbon dioxide rising through the air gains mechanical energy (as well as gravitational potential energy).Thermal energy: The heating of fossil fuels releases the energy stored inside.Electrical energy: Burning fossil fuels creates electrical energy for us to use.
OPTIONS:
a. The organisms vary in trait
b. The variation is inherited
c. More young are born than can survive
d. Some individuals are better adapted to the environment
Answer:
d. Some individuals are better adapted to the environment
Explanation:
Kettlewell’s biological experiment, which was conducted in England, was to study the evolutionary changes taking place in trees in relation to the appearance of dark-colored moth.
It was observed that white moths were more common before the industrial revolution. After the industrial revolution, which changed the background of the environment of the moths due to pollution, the moths became easily seen and obvious to predatory birds.
It was discovered that peppered moths were selectively preyed on by birds depending on their body color, which serves as the most important factor that determines if moths can survive predation by blending with the background of their environment. This led to the evolving of moths of their color to blend with the background of their environment, which makes them hide from the birds that prey on them.
Kettlewell was trying to verify the factor in evolution by natural selection, which says, “some individuals are better adapted to the environment”.
