Answer:
(A) greater than standing crop of fish
Explanation:
Biomass -
It is the mass of the living organisms in a particular area of the ecosystem at a particular time . It even includes the animals , plants and microorganisms .
It is the total mass of the community or the average mass per unit area .
The biomass of the phytoplankton are always more than the biomass of the fish .
Hence the correct statement would be (A) greater than standing crop of fish .
The statement is false.
Earth is not a ''spaceship'', and that term is used only metaphorically in some studies about the future of the human kind, in the sense of ''can the Earth be used as a spaceship to bring us to another place'', and theorize about that.

Answer:
Th similarities between the black hole and the neutron star is that they are formed from dead (dying) starts. But they come from different parent stars, if the parent star is 1.4 times the mass of the sun, a neutron star will be formed, but if the parent star is twice the mass of the sun a black hole is formed.
Explanation:
A black hole is defined as an area of space whereby the matter is so compacted that nothing can escape from it. This area is called <em>event horizon. </em>Black holes are formed when an enormous star dies in z supernova. They weigh at least twice the sun's mass, and their mass is directly proportional to their radii.
Neutron stars are created during supernova and maintained by a neutron called <em>degeneracy pressure.</em> Neutron star has a small radius, typically 30 km, with a very high density made up of compacted neutrons.
