Homeostasis Review

Front

What is the role of fungi in an ecosystem?

Back

Fungi are heterotrophic, eukaryotic organisms that decompose dead material, recycling nutrients back into the ecosystem.

Front

What is a stimulus in biological terms?

Back

A stimulus is a change in the environment that causes a response in an organism.

Front

What are lipids and their function in living organisms?

Back

Lipids are biomolecules found in fats, oils, and waxes, serving as a source of long-term energy.

Front

What is the difference between a stimulus and a response?

Back

A stimulus is the cause of a change, while a response is the effect or reaction to that stimulus.

Front

What is the primary difference between autotrophic and heterotrophic organisms?

Back

Autotrophic organisms can make their own food through processes like photosynthesis, while heterotrophic organisms cannot and must consume other organisms for energy.

Front

Define homeostasis in biological systems.

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers, like fungi, break down dead organic matter, returning essential nutrients to the soil and supporting plant growth.

Front

How do autotrophs contribute to the energy flow in an ecosystem?

Back

Autotrophs convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.

Front

What is the relationship between stimuli and responses in organisms?

Back

Organisms detect stimuli through sensory receptors and respond to them through various physiological or behavioral changes.

Front

What are the main types of biomolecules, and what roles do they play in living organisms?

Back

The main types of biomolecules are carbohydrates (energy source), lipids (long-term energy storage), proteins (structural and functional roles), and nucleic acids (genetic information).
