what percentage of the energy flowing through primary producers is ultimately transferred to secondary consumers?

Answers

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. Hypothetically, we can assume that about 6000 kilocalories per square meter per year these autotrophs can collect and store energy. Primary consumers like omnivores such as deer, cow, birds and etc. receive almost 10% as much from these autotrophs. Secondary consumers receive for as much as 1% of the total energy that was from the autotrophs.

Sharks have highly developed _____.thermoreceptors
photoreceptors
olfactory receptors
mechanoreceptors

Answers

Among the options the best answer is "olfactory receptors" - as the sharks have a very good sense of smell. (they have the other receptors, but not as developed)
however, they are more famous for their electroreceptrors- they can sense the electric current around them!

Answer: olfactory receptors

Sharks have highly developed olfactory receptors. The olfactory receptors in animals allows them to sense the odor. Sharks have olfactory receptors more sensitive than humans. They have nostrils located on the underside of their snout, which they use for smelling not for breathing. The smell of the prey animal or the blood of any animal is detected by the shark with the help of these receptors.

Potatoes were the main crop in Ireland in the 1800s. Almost the entire population of Ireland was dependenton a single variety of potato, the “lumper.” These potatoes were reproduced by a method of asexualreproduction known as vegetative propagation. In the middle of the 1800s, a disease caused by a funguskilled almost the entire lumper crop within two years. As a result, millions of people in Ireland died of starvation.The most likely reason the potato disease was able to destroy the potato crop in such a short time is that the(1) potato population lacked variations(2) lumper variety had a long reproductive cycle(3) lumper had several variations caused by vegetative propagation(4) potato population in Ireland utilized all of the finite resources
