What is the composition of a virus?

Back

A virus consists of a nucleic acid (either DNA or RNA) surrounded by a protein capsid.

Front

What are primary consumers in an ecosystem?

Back

Primary consumers are organisms that eat producers (plants) for energy, such as rabbits, mice, and seed-eating birds.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process of converting atmospheric nitrogen into a usable form for plants, primarily carried out by bacteria.

Front

What type of organic molecule is a waxy coating on plants?

Back

The waxy coating on plants is a lipid, which helps reduce water loss.

Front

What is one function that roots do not perform?

Back

Roots do not take in carbon dioxide; they primarily absorb water and minerals from the soil.

Front

What is the role of bacteria in the nitrogen cycle?

Back

Bacteria play a crucial role in nitrogen fixation and decomposition, converting nitrogen into forms usable by plants.

Front

Define primary consumers with an example.

Back

Primary consumers are herbivores that eat plants; for example, rabbits and deer.

Front

What is the function of a protein capsid in viruses?

Back

The protein capsid protects the viral genetic material and helps the virus attach to host cells.

Front

What are lipids and their function in plants?

Back

Lipids are organic molecules that serve as energy storage and form protective barriers, such as waxy coatings on leaves.

Front

Explain the process of photosynthesis in simple terms.

Back

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.
