A lot of change throughout the years
Answer:
Invertebrates have a very quick life cycle and die very easily, as a result, they evolve very quickly into many different types of animals. also, they are often very small and their ecosystems are subject to much quicker change than that of vertebrates, meaning that mutations in their genes become relevant more often. Many invertebrates span very large areas (sea animals span most of the oceans, insects span entire continents) and so they evolve to be different species in different places.
Or
They do not have bones, they live on water or land, they can have soft bodies or exoskeletons, and others are parasites.
Answer:
The correct answer is option D, that is, waves increase oxygen availability in the ocean increasing abundance.
Explanation:
The conduction of energy from the wind to the water environment takes place with the help of waves. It plays a prime function in the survival of life in the oceans. The prime function of waves is to clean the surface and assists in oxygenating the water present below the surface. The waves also facilitate in carrying nutrients along the shorelines for the marine species.
