Organisms in aquatic ecosystems can be categorized based on their method of mobility in the water. Which of the following would be categorized as benthos? O ultraplankton because they float and perform photosynthesis O jellyfish and krill because they float and feed on other organisms O turtles and fish because they swim and feed in the large open water O crabs and oysters because they move and live along the bottom surface

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
