Biogeochemical Cycles

Front

What is a producer in an ecosystem?

Back

A producer is an organism that makes its own food, typically through photosynthesis.

Front

Why are producers considered the foundation of a food chain?

Back

Producers are the first organisms in a food chain because they provide the energy necessary for other living organisms.

Front

What is the process of eutrophication?

Back

Eutrophication is the process where water bodies become overly enriched with nutrients, leading to excessive growth of algae.

Front

How do bacteria contribute to fish deaths during eutrophication?

Back

Bacteria use up oxygen in respiration, which can lead to hypoxic conditions and the death of fish.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers recycle dead materials back into the ecosystem, breaking down organic matter and returning nutrients to the soil.

Front

What is the chemical formula for glucose?

Back

The chemical formula for glucose is C6H12O6.

Front

What are the main components of the carbon cycle?

Back

The main components of the carbon cycle include photosynthesis, respiration, decomposition, and combustion.

Front

How does photosynthesis contribute to the carbon cycle?

Back

Photosynthesis allows producers to convert carbon dioxide from the atmosphere into organic compounds, releasing oxygen as a byproduct.

Front

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

Back

Nitrogen-fixing bacteria convert atmospheric nitrogen into ammonia, making it available for plants.

Front

What is the process of denitrification?

Back

Denitrification is the process by which bacteria convert nitrates back into nitrogen gas, returning it to the atmosphere.
