How biogeochemical cycles affect our earth

Human activities have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered biogeochemical cycles combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.

Explanation:

Why is the biogeochemical cycles important to Earth?

These cycles are called biogeochemical cycles, because they include a variety of biological, geological, and chemical processes. Many elements cycle through ecosystems, organisms, air, water, and soil. ... The biogeochemical cycles transport and store these important elements so that they can be used by living organisms.

How are Earth's biogeochemical cycles connected?

The biogeochemical cycles on Earth connect the energy and molecules on the planet into continuous loops that support life. The basic building blocks of life like water, oxygen, carbon, sulfur, nitrogen and phosphorous are recycled and go back into their respective cycles repeatedly

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
