How do plants, animals, and humans depend on one another?

Plants, animals, and humans are interconnected in various ways that contribute to the health of ecosystems and the survival of each species. The correct choice highlights this interdependence effectively.

Plants play a crucial role in the ecosystem by performing photosynthesis, which produces oxygen and forms the base of the food chain. They rely on animals and humans for seed dispersal, enabling them to reproduce and spread. This interaction not only helps plants propagate their species but also enables animal species to thrive.

Animals, in turn, rely heavily on plants for nutrients, as they provide food sources in the form of fruits, leaves, and seeds. This relationship underscores the nutritional dependency within the food web. Furthermore, all living organisms, including plants, animals, and humans, require essential resources like water, air, and sunlight to survive. This emphasizes a shared reliance on fundamental environmental elements that sustain life.

While the other options touch upon aspects of interdependence, they do not encompass the full scope of relationships as effectively as the chosen answer. For instance, while it is true that plants provide oxygen and nutrients, and animals consume plants and humans consume animals, these points don’t capture the complex interactions such as seed dispersal and the essential roles each group plays in maintaining the ecosystem’s
