Answer:
According to the law of conservation of matter, matter is never created or destroyed but it can change from one form to another. Most of the biomass in a food web gets converted at each trophic level and it no longer remains apart of the food web. Most of the biomass is released into the atmosphere in the form of heat and hence cannot be transferred to the other trophic level.

The 4 factors affect evolution, according to Darwin’s Origin
of Species are;
Variation
Heritability
Competition
Differential survival
Variation ensures that
there is variability of population traits
on which selection pressures will apply.
Heritability means that the traits must be able to be passed down to offsprings through gametes.
Competition occurs when the individuals in the population compete for limited resources
Differential survival
occurs due to competition for resources
and other selection pressures. This result
to the survival of the strongest and weeding
out of the weak from the population.
