Conceptual Biology Midterm Review

Front

Which level has the MOST energy in the energy pyramid?

Back

Producers have the most energy in the energy pyramid as they are the primary source of energy for all other levels.

Front

What is the function of an enzyme?

Back

Enzymes speed up chemical reactions in the body by lowering the activation energy required.

Front

What type of growth is shown in the graph?

Back

Exponential growth is characterized by a rapid increase in population size when resources are abundant.

Front

What is the average monthly precipitation in June?

Back

The average monthly precipitation in June is 65 mm.

Front

Which is NOT considered part of The Cell Theory?

Back

Cells do not divide is NOT part of The Cell Theory; the theory states that all living things are made of cells, cells are the basic unit of structure and function, and cells come from pre-existing cells.

Front

What are the three main components of the Cell Theory?

Back

1. All living things are made of cells. 2. Cells are the basic unit of structure and function. 3. All cells come from pre-existing cells.

Front

Define producers in an ecosystem.

Back

Producers are organisms that create their own food through photosynthesis or chemosynthesis, forming the base of the food chain.

Front

What is the role of primary consumers in an ecosystem?

Back

Primary consumers are herbivores that eat producers and convert the energy stored in plants into a form that can be used by higher trophic levels.

Front

Explain the difference between logistic and exponential growth.

Back

Logistic growth occurs when a population's growth slows as it reaches carrying capacity, while exponential growth occurs when resources are unlimited, leading to rapid population increase.

Front

What is the significance of enzymes in biological processes?

Back

Enzymes are crucial for facilitating biochemical reactions, allowing processes like digestion and metabolism to occur efficiently at body temperature.
