Phytoplankton refers to the microscopic marine species that thrive at the bottom of the food chain. They obtain their energy from carbon dioxide via photosynthesis, like plants and thus are very essential in carbon cycling.
Phytoplankton forms the base of almost every ocean food web. Thus, it can be stated that they make the majority of other ocean life possible. They are the source of food for zooplankton and small fishes, as well as for larger animals like jellyfish and whales.
Thus, if the population of phytoplankton gets declined, it will indirectly affect other species in the aquatic ecosystem. It can also be said that with the decrease in the population of phytoplankton, the population of other major species in the ecosystem also gets a decline.
Answer:
e. spores
Explanation:
In the given question, the characteristics of a plant are mentioned which are the dominant sporophyte, cell wall and the Chl a or b.
It is mentioned that the plant has a dominant sporophyte therefore it produces the spores during its life cycle. The other features like the endosperm, seeds, flowers are the characteristics on the basis of which the plant can be characterised as they differ in the plants.
Since the production of spores is a characteristic feature of the sporophyte, therefore, it will be least considered by the botanist to discover a new species.
Thus, Option-E is the correct answer.
C.The body has higher requirements for water-soluble vitamins
well ofc air is just one of the products we get from photosynthesis
