Question

What are the 4 types of processes that cycle matter through the biosphere give examples?

Answer 1

The four types of processes that cycle matter through the biosphere are called biogeochemical cycles. The nitrogen cycle is an example, involving processes like nitrogen fixation, decay, nitrification, and denitrification, with microorganisms playing key roles in making nutrients accessible in the ecosystem.

Step-by-step explanation:

The four types of processes that cycle matter through the biosphere are known as biogeochemical cycles. These cycles include the water cycle, carbon cycle, nitrogen cycle, and other essential element cycles. Here are four processes within the nitrogen cycle as an example:

1. Nitrogen fixation - Certain microorganisms convert atmospheric nitrogen (N2) into ammonia (NH3) which can be used by plants.
2. Decay - Decomposers like bacteria and fungi break down dead organisms, releasing nitrogen into the soil as ammonium (NH4+).
3. Nitrification - This process converts ammonium into nitrite (NO2-) and then into nitrate (NO3-), which can be absorbed by plants.
4. Denitrification - In anaerobic conditions, other bacteria convert nitrates back into atmospheric nitrogen.

Microorganisms play a fundamental role in these processes, making nutrients available to the rest of the ecosystem. Plants also contribute, for example, through transpiration, moving water from the soil to the atmosphere. These cycles are crucial for the sustainability of life on Earth as they ensure the constant recycling of vital elements.
