Answer:
Only 10% of the mass and energy is transferred
Explanation:
In a food chain, organism at a certain trophic level, obtain nutrition and energy from organism lying at its preceding trophic level.
As per the rule of energy pyramid, a higher organism feeding on any low level organism in a given food chain obtain only 10% of the total energy. The remaining 90% of the energy remains with the organism to carry out its metabolic processes including decomposition or self destruction.
Answer:Water masses give a very robust representation of the thermohaline state of the ocean and ocean circulation. ... This water body shows extremely stable vertical stratification, and its water density changes from ~1,011 kg/m3 at the ocean surface to ~1,016 kg/m3 at 100‐m depth.

Explanation:
Natural selection is process of differential survival and reproduction of the organisms which have better phenotypic traits over the other members of the same species. These traits help the organism to survive in unfavorable conditions and they are passed from the parents to the offsprings and through successive generations of the species.
For example, the development of long neck of the giraffe helped them to grab leaves from tree tops.
