Dwarf planets have round shape and orbit the sun. They do not clear their orbits due to smaller gravitational pull and hence, cannot be classified as a planet. A dwarf planet may or may not have moons. Dwarf planets are smaller in size than planets.
Pluto was once classified as planet but was demoted to dwarf planet as many other similar sized objects were found in its neighborhood in Kuiper belt (Eris, Haumea, Makemake) . One dwarf planet is present in asteroid belt as well. It is the largest object in the asteroid belt.
Answer:
The correct answer is C. co-evolution
Explanation:
When two or more species evolution is influenced by each other and are interdependent than this type of evolution is known as co-evolution. There are several examples of co-evolution like predator-prey co-evolution, flowering plants and pollinators evolution, etc.
The predator-prey evolution is famous in which there is selective pressure on prey to evolve to avoid getting hunted and the same pressure is on predator to evolve with prey so that they can get their food and survive. Therefore the correct answer is co-evolution.
