EOC Biology Review #5

Front

What molecule supplies energy for most chemical reactions in cells?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells.

Front

What element is released by the weathering of rocks?

Back

Phosphorus is released during the weathering of rocks.

Front

What would happen to populations if there is a reduction in grass?

Back

A reduction in grass would lead to a decrease in all other populations that depend on it for food.

Front

What explains the difference in available energy in trophic levels of an ecosystem?

Back

There is less available energy in higher trophic levels due to energy loss through metabolism in lower levels.

Front

Which suspect is linked to a crime scene by DNA analysis?

Back

Suspect C is linked to the crime scene based on DNA analysis.

Front

Define ATP.

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells.

Front

What is the role of producers in an ecosystem?

Back

Producers convert sunlight into energy through photosynthesis, forming the base of the energy pyramid.

Front

Explain the concept of an energy pyramid.

Back

An energy pyramid illustrates the flow of energy through different trophic levels in an ecosystem.

Front

What is the significance of phosphorus in ecosystems?

Back

Phosphorus is essential for DNA, RNA, and ATP, and is a key nutrient for plant growth.

Front

How does energy transfer between trophic levels?

Back

Energy transfer between trophic levels is inefficient, with only about 10% of energy passed to the next level.
