What is the nitrogen cycle?

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including atmospheric nitrogen, organic nitrogen in living organisms, and nitrogen in the soil.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria convert atmospheric nitrogen into forms that plants can use, such as ammonia, and also help in the decomposition of organic matter, returning nitrogen to the soil.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

How does energy transfer in an energy pyramid?

Back

Energy transfer in an energy pyramid occurs when energy from the sun is converted into chemical energy by producers (like plants), which is then passed on to consumers (like animals) at each trophic level, with energy loss at each step.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and the genetic diversity within those species.

Front

Why is biodiversity important for ecosystem sustainability?

Back

Biodiversity enhances ecosystem resilience, allowing ecosystems to adapt to changes and recover from disturbances, such as natural disasters.

Front

What is a habitat?

Back

A habitat is the natural environment in which an organism lives, providing the necessary resources for survival, such as food, water, and shelter.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a complex network of interconnected food chains in an ecosystem.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, are organisms that create their own food through photosynthesis and serve as the primary source of energy for consumers in an ecosystem.

Front

What is the significance of thermal energy loss in energy transfer?

Back

Thermal energy loss during energy transfer indicates that not all energy is passed on to the next trophic level, which limits the number of trophic levels in an ecosystem.
