Which of the following is a food chain in the food web shown in the figure below?

Answers

First we have to understand that a food chain is a series of steps in which organisms transfer energy by eating and being eaten. A food web is a feeding relationship among the various organisms in an ecosystem that forms a network of complex interactions. A food web links all the food chains in an ecosystem.

Darwin hypothesized that there are definite steps to natural selection. Consider the model here. Use the Roman numerals (I - III) to guide you through the steps. Which is an accurate description of Darwin's hypothesized theory of natural selection? A) Sexual reproduction of bacteria cause variation. Some bacteria survive and some do not. Over time all of the bacteria should become extinct. B) In any population, variation exists. Some bacteria are resistant to antibiotics. Most bacteria die, but the bacteria that are resistant survive and reproduce. C) In a population of bacteria that are exposed to antibiotics, some bacteria change their genetic make-up and survive. The new genetic make-up is passed on to offspring. D) There is a change in the environment: an antibiotic is added. Some of the bacteria are capable of changing to the new environment. They survive and reproduce, passing along their favorable traits.

Answers

Answer: Option D

Explanation: Natural selection come into action when some change takes place in the environment which affects the survival of the organism. Here the change is addition of antibiotics. So the bacterial cells which were able to adapt to the change, they survived and rest were killed. These resistant bacterial cells would pass on the genes to next generation and gradually population of resistant bacteria would increase.
