APES Nutrient Cycles

Front

What is the only process that removes carbon from the atmosphere?

Back

Photosynthesis is the process by which plants convert carbon dioxide from the atmosphere into glucose and oxygen, effectively removing carbon from the atmosphere.

Front

In which biogeochemical cycles are humans most affecting the natural greenhouse effect?

Back

Humans are most affecting the Carbon, Nitrogen, and Water cycles, contributing to climate change and environmental degradation.

Front

What is the process of plants losing water through their leaves called?

Back

Transpiration is the process where plants release water vapor into the atmosphere through small openings in their leaves called stomata.

Front

What is a place where matter/nutrients are collected/stored?

Back

A reservoir is a natural or artificial place where nutrients and matter are stored, such as lakes, oceans, or underground aquifers.

Front

How do animals get the phosphorus they need?

Back

Animals obtain phosphorus by eating plants or other animals that have consumed plants, as phosphorus is an essential nutrient for biological processes.

Front

What is the role of nitrogen-fixing bacteria in the nitrogen cycle?

Back

Nitrogen-fixing bacteria convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants in a usable form.

Front

What is the significance of the water cycle in ecosystems?

Back

The water cycle is crucial for maintaining ecosystem health, supporting plant growth, regulating climate, and providing habitats for various organisms.

Front

Define the term 'biogeochemical cycle'.

Back

A biogeochemical cycle is the movement of elements and compounds through biological, geological, and chemical processes in the environment.

Front

What is the process of decomposition and its importance in nutrient cycling?

Back

Decomposition is the breakdown of organic matter by microorganisms, returning essential nutrients to the soil and making them available for plant uptake.

Front

Explain the concept of 'reservoir' in nutrient cycles.

Back

A reservoir in nutrient cycles refers to a storage location for nutrients, such as the atmosphere for carbon or oceans for water.
