In which of the following pair radii of second species is smaller than...

First Species:

- Radius: 5 cm

Second Species:

- Radius: 4 cm

Explanation:

Firstly, let's understand the concept of the radius of the species. The radius of a species is a fundamental property that determines the size of the species. It is the distance from the center of the species to its outer edge.

Comparison of Radii:

In this case, the radius of the second species (4 cm) is smaller than that of the first species (5 cm). This means that the second species is physically smaller in size compared to the first species.

Reasoning:

The radius of a species is directly related to its size. A smaller radius indicates a smaller size, while a larger radius indicates a larger size. Therefore, in this pair, the second species has a smaller radius, making it physically smaller than the first species.
In conclusion, when comparing the radii of the two species, it is evident that the radius of the second species is smaller than that of the first species. This difference in size can have implications for various aspects of the species, such as its behavior, habitat, and interactions with other species.

Similar UPSC Doubts

A species that exertsan influence out of proportion to its abundance in an ecosystem is called a keystone species. The keystone species may influence both the species richness of communities and the flow of energy and materials through ecosystems. The sea star Pisaster the flow of energy and materials through ecosystems. The sea star Pisaster ochraceus, which lives in rocky intertidal ecosystems on the Pacific coast of North America, is also an example of a keystone species. Its preferred prey is the mussel Mytilus californianus . In the absence of sea- stars, these mussels crowd out other competitors in a broad belt of the intertidal zone. By consuming mussels, sea star creates bare spaces that are taken over by a variety of other species. A study at the University of washington demonstrated the influence of Pisaster on species richness by removing sea stars from selected parts of the intertidal zone repeatedly over a period of five years. Two major changes occured in the areas from which sea stars were removed. First, the lower edge of the 46. mussel bed extended farther down into the intertidal zone, showing that sea stars are able to eliminate mussels completely where they are covered with water most of the time. Second, and more dramatically, 28 species of animals and algae disappeared from the sea star removal zone. Eventually only Mytilus, the dominant competitor, occupied the entire substratum. Through its effect on competitive relationships, predation by Pisaster largely determines which species live in these rocky intertidal ecosystems.Q. With reference to the passage, consider the following statements : 1. Mussels-are generally the dominant species in intertidal ecosystems. 2. The survival of sea stars is generally determined by the abundance of mussels. Which of the statements given above is /are correct?

If the keystone species is completely removed from an ecosystem, it will lead to the collapse of the ecosystem.With reference to the passage, which of the above assumptions is/are valid?
