Final answer:
A community encompasses diverse populations adapted to their habitat, exhibiting various interactions that determine species richness and survival strategies. Biomes represent these communities with specific environmental conditions, and ecological studies focus on interactions like competition and biodiversity within these communities.
Step-by-step explanation:
Each community has unique characteristics and supports different populations of producer and consumer organisms that have adapted to life in each habitat. A biome is an ecological community of plants, animals, and other organisms that is adapted to a characteristic set of environmental conditions. Communities are not only about the variety of species, known as species richness or biodiversity, but also about the complex interactions among these species, such as predation, herbivory, symbiotic relationships, and competition for resources. Animal species differ widely in their food sources and have evolved mechanical defenses, warning coloration, and mimicry to survive in their ecological niches. Community dynamics are influenced by environmental variables like latitude, amount of rainfall, and geography, which in turn affect species richness. Ecology studies these interactions at the community level to better understand how species coexist and compete within a given habitat.
