Nutrient Cycles, Ecological Succession, and Biomes

Answer

Nutrient cycles refer to the continuous movement and recycling of essential chemical elements between the biotic components and the abiotic components of the environment. They are also called biogeoch…

Answer

The three main pools are Reservoir Pool, Exchange Pool, and Biotic Pool. Reservoir Pool stores nutrients for long periods in an inactive form, Exchange Pool holds nutrients that are readily available,…

Answer

This is the Reservoir Pool. Rocks act as a long-term storage area for nutrients such as phosphorus.

Answer

They keep essential elements available for living organisms and help maintain ecosystem balance. Without recycling, nutrients would get locked away and life would not be sustained properly.

Answer

Producers absorb nutrients from the environment. Animals get those nutrients by eating plants or other animals. When organisms die, decomposers break down their bodies and release nutrients back into …

Answer

The carbon cycle controls the movement of carbon between the atmosphere, living organisms, soil, and oceans. Carbon is a basic building block of all organic molecules, so this cycle is essential for l…

Answer

The biological processes are photosynthesis, respiration, and decomposition. Plants and algae take in carbon dioxide during photosynthesis, organisms release carbon dioxide during respiration, and dec…

Answer

The geological processes are fossilisation and volcanic activity. Dead organisms can form fossil fuels over millions of years, and volcanic eruptions release carbon dioxide stored in the Earth's crust…
