Answer:
Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as by holding a heavy book or a dumbbell at the same position. The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.
Explanation:
Answer: 1. a biological community of interacting organisms and their physical environment.
2. Next come the omnivores that eat a mixture of plants and herbivores. That's where humans rank, with a trophic level of 2.2. Above us are carnivores, such as foxes, that eat just herbivores. At the top of the scale are meat-eaters that don't have any predators themselves, such as polar bears and orca whales.
