In the food chain every time it attains the higher trophic level only ten per-cent of total energy is transferred. The higher trophic level populations in a food chain are larger because the biomass needs to be maintained as there are fewer organisms the biomass is distributed to maintain the equilibrium in the ecosystem.
Explanation:
The less energy passed on to the higher level would cause less population in the higher trophic level and biomass gets distributed so the organisms keep increasing in the size at the higher trophic level.
The answer is SPORES.
Some bacteria, take for example clostridium can be killed with heat but still leave their spores.
They are heat-resistant spores that may survive cooking and later grow and produce large numbers of cells if the storage temperature is appropriate for their growth.
Answer:
Ocean currents are the routed movements of oceanic water which are constantly flowing within the ocean or on the ocean surface. An ocean current is created by several forces and elements that act upon a unit mass of water in the ocean and such factors on an environmental scale include the gravitational pull of the Moon and the Sun, wind, salinity levels, and the rotation of the earth, temperature and tidal waves. However, the two forces that create the most conducive conditions for a current to form are the Sun and the rotation of the Earth.
