Biotic and Abiotic Factors Quiz

What is the difference between abiotic and biotic factors? Choose the correct examples of each.

• Abiotic factors include sunlight and temperature; biotic factors include plants and animals.

• Abiotic factors include plants and animals; biotic factors include sunlight and temperature.

• Abiotic factors include water and soil; biotic factors include rocks and minerals.

• Abiotic factors include bacteria and fungi; biotic factors include air and water.

Answer explanation

Abiotic factors are non-living elements like sunlight and water, while biotic factors are living organisms such as plants and animals. Examples: Abiotic - temperature, soil; Biotic - trees, insects.

Is a fallen leaf an example of an abiotic or a biotic factor? Why?

Answer explanation

A dead tree is an example of a biotic factor because it was once a living organism. Although it is no longer alive, it still originates from a biological source.

Classify these examples as either abiotic or biotic.

Answer explanation

Abiotic factors are non-living components like water and sunlight, while biotic factors are living organisms such as plants and animals. Classify examples accordingly based on their nature.

What two life processes make the energy cycle go round and round?

Answer explanation

The two life processes that drive the energy cycle are photosynthesis and cellular respiration. Photosynthesis converts solar energy into chemical energy, while cellular respiration releases that energy for use by living organisms.

What gas do animals release into the air? (What gas do YOU breathe out?)

(a)  

Answer explanation

Animals release carbon dioxide into the air when they breathe out. This gas is a byproduct of respiration, which is the process of converting food into energy.

What gas do plants release into the air that is used by animals?

(a)  

Answer explanation

Plants release oxygen during photosynthesis, which is essential for animals to breathe. This gas is crucial for their survival, making oxygen the correct answer.

What is the correct order of the levels of biological organization from smallest to largest?

Answer explanation

The correct order of biological organization from smallest to largest is: cell, tissue, organ, organ system, organism. This hierarchy illustrates how complex structures are built from simpler units.

How are energy and nutrients transferred through an ecosystem?

Answer explanation

Energy and nutrients are transferred through an ecosystem via food chains and food webs. Producers convert sunlight into energy, which is then passed to consumers and decomposers, maintaining the flow of energy and nutrients.

What captures energy from the sun and stores it in chemical bonds of glucose?

Answer explanation

Photosynthesis captures energy from the sun using chlorophyll in plants, converting it into chemical energy stored in glucose molecules.

Which level in a Pyramid of Energy has the most stored energy? Why?

Answer explanation

The top level of the Pyramid of Energy has the most stored energy because it consists of primary producers, like plants, which convert sunlight into energy through photosynthesis, storing the most energy compared to other levels.
