<span>Energy transfer is the
transmission of food energy from organism to the next which is illustrated as
the food chain. Normally and typically, the autotrophs are the photosynthetic
organisms that primary makes food for itself and for other organisms.
</span><span>Hypothetically, we can assume that about 6000 kilocalories per square meter per
year these autotrophs can collect and store energy.</span><span> Primary consumers like
omnivores such as deer, cow, birds and etc. receive almost 10% as much from
these autotrophs. </span><span>Secondary consumers receive for as much as 1% of the total
energy that was from the autotrophs.
