The graph illustrates a predator prey relationship.
A predator can be described as an organism that eats other organisms while the prey is the animal that is killed and eaten by the predator. Both the predators and the preys usually co-exist in the same ecosystem. The relationship between the predator and the prey affect the population of the organisms in all ecosystem; it determines the mortality of preys and the birth of new predators.
Cardiac muscle cells get all the oxygen they need from the coronary arteries. They do not gather oxygen from the blood flowing inside them but from the blood as received from the coronary arteries. Hope this answers the question. Have a nice day.
Segmentation allows for a greater degree of variety among species
The concept of segmentation relies upon the ability for organisms to duplicate organs and structural elements, such as arms and legs
The ability to divide functions into different portions of the body allows an organism to perform increasingly complex activities and use different segments to perform varying functions
For example, humans consist of heteromeric segmentation, in which each segment differs from another and fulfills a specific role
Homomeric segmentation refers to segments that contain similar elements, such as with the segments in an Errantia, a type of worm
