Large predators are found at higher trophic levels, what does this mean in terms of energy loss ?
VARVARA [1.3K]

Large predators are found at higher trophic levels because specialized bodies are needed to extract the small energy that gets to them.

The energy that gets to successive trophic levels decreases progressively because much of it is lost as heat. This means that a small percentage of the energy from the producers that form the bases of trophic levels to the predators that are somewhat at the top of trophic levels.

With big body size, the bodies of predators are organized into systems that work together to efficiently extract the small energy that gets to them from immediate lower trophic level.

More on the energy from trophic levels can be found here: brainly.com/question/13375401?

LIttle Jimmy Brown's blood typing results showed agglutination with both the plasma containing anti A and anti B antibodies. Wha
Marat540 [252]

Answer:

Jimmy's blood type: "O" Blood

Jimmy can receive blood from: O blood type only.

Explanation:

The anti-A antibodies are present in the plasma of "B" blood type. Similarly, the blood type "A" has anti-B antibodies in its plasma. Since Jimmy's blood is showing agglutination with both "A" and "B" blood type, he has "O" blood type.

The "O" blood type has both anti-A and anti-B antibodies in its plasma and exhibits agglutination with both A and B blood type. The "A" antigen of "A" blood type reacts with anti A antibodies of jimmy's blood while "B" antigen of "B" blood type would exhibit agglutination with "anti B antibodies" of Jimmy's blood. He can get blood from "O" blood type only as he has both anti-A and anti B antibodies in his blood plasma.
