Biology Final

A student is developing a model of the carbon cycle. She wants to include an example that shows the interaction between the atmosphere and the geosphere.

• Plants undergoing photosynthesis to convert carbon dioxide into biomass.

• Fossil Fuels being burned and releasing carbon dioxide into the air.

• Fish dying in the ocean and decomposing on the ocean floor.

Which process shows the uptake of carbon from the atmosphere to the biosphere?

• Cellular respiration

• Photosynthesis

• Decomposition

What role do decomposers have in the carbon cycle?

• Decomposers release carbon dioxide into the atmosphere.

• Decomposers do not have a role.

• Decomposition locks carbon into soil.

Which is a benefit of using a model?

• A model shows all of the events of a real phenomenon.

• A model predicts conditions of future events.

• A model explains concepts that are difficult to show.

Photosynthesis is the term used to describe the process by which light energy from the sun is converted into chemical energy.

• TRUE

• false

An organism that is classified as anaerobic can perform respiration

• without hydrogen

• with oxygen only

• without oxygen

Utah's Great Salt Lake has an extraordinary amount of salt. The water is basic, oxygen is present. Which extremophile can thrive in this environment?

• halophiles

• acidophiles

How would the absence of a standardized taxonomic system affect scientific communication?

• It would create confusion as scientists tried to accurately discuss and compare organisms.

• It would lead to clearer communication as scientists could use common names.

A student observes an organism through a microscope. She notices that it has a unicellular structure, a nucleus, and moves using cilia. Based on these characteristics, how should the organism be classified?

• As a Fungi because it moves using cillia.

• As a Protista because it is unicellular with a nucleus.

Consider the factors that affect the carrying capacity of a fish population in a small pond, and one in a large ocean bay. Which statement accurately reflects the significance of factors affecting the carrying capacity based on the scale of the ecosystem?

• Seasonal temperature changes have a larger impact on the carrying capacity of the ocean bay due to its size.

• Pollution affects the carrying capacity of the pond more than the ocean bay.

• Food availability has the smae impact on carrying capacity for both the pond and the ocean bay.
