Final exam biology

Front

What is secondary succession?

Back

Secondary succession is the process of ecological recovery that occurs in an area where a disturbance has destroyed a community but left the soil intact.

Front

Why does secondary succession occur faster than primary succession?

Back

It occurs faster because the soil is already present, allowing plants to grow more quickly.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers; for example, a snake that eats mice.

Front

What is a virus?

Back

A virus is a microscopic infectious agent that requires a host cell to reproduce and cannot replicate on its own.

Front

What is the fossil record?

Back

The fossil record is the collection of fossils that provides evidence of the history of life on Earth and supports the theory of common ancestry.

Front

Where does carbon dioxide (CO2) enter the leaves of a plant?

Back

CO2 enters the leaves through small openings called stomata.

Front

What role do stomata play in plants?

Back

Stomata are responsible for gas exchange, allowing CO2 to enter and oxygen to exit the leaf.

Front

What is the difference between a predator and a parasite?

Back

A predator hunts and kills its prey for food, while a parasite lives on or in a host organism and derives nutrients at the host's expense.

Front

What is the significance of comparative anatomy in understanding evolution?

Back

Comparative anatomy studies the similarities and differences in the structures of different species, providing evidence for common ancestry.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
