Step-by-step explanation:
Giraffes, lions, zebras, hyenas, and all the other living things of the Serengeti make up a community. This community includes all the different species living in a given area. The variety of these species is referred to as biodiversity, which is a crucial aspect of community structure. Community relationships encompass symbiosis, predation, and competition among species, and they describe how populations interact within their habitat. Moreover, the community is a part of a larger system known as an ecosystem, which also includes abiotic factors such as climate and soil composition.
